Delta Variant, R.S.V. Infections Rising Amongst Kids

Delta Variant, R.S.V. Infections Rising Among Children

Health officials have raised concerns about a simultaneous rise in Delta infections and cases of Respiratory Syncytial Virus (RSV), a highly contagious, seasonal flu-like illness that is more likely to affect children and older adults.

Cases of RSV have risen gradually since early June, with an even bigger increase over the past month, according to data from the Centers for Disease Control and Prevention. RSV, which can cause symptoms such as a runny nose, cough, sneeze, and fever, usually begins to spread in the fall, which makes this summer unusual.

In a series of posts on Twitter, Dr. Heather Haq, a pediatrician at Texas Children’s Hospital in Houston, reported a surge in hospital admissions from coronavirus and RSV.

“After many months with no or few pediatric Covid cases, we are seeing infants, children and adolescents with Covid flow back to the hospital more and more every day,” she wrote, adding that the ages of the patients ranged from 2 weeks to 17 Years old, including some with Covid pneumonia.

“We are at the front end of a huge surge in Covid,” wrote Dr. Haq, who was unavailable for comment on Sunday. “We now have winter-level patient numbers of acutely ill infants / toddlers with RSV, and I fear we will run out of beds and staff to handle the surge.”

Coronavirus Pandemic and Life Expectancy in the United States

RSV cases in Texas began to increase in early June and appeared to peak in mid-July, according to the state Department of Health.

There has been a similar surge in RSV cases in Florida, where infections “were higher than in previous years at this point in time,” according to a surveillance report.

In Louisiana, where cases have risen 244 percent in the past two weeks, Our Lady of the Lake Children’s Hospital in Baton Rouge was nearing capacity on Friday, CNN reported.

“You start with the pandemic for the last 18 months and then with RSV for the last few months. It just seems like one thing at a time that keeps our teams very busy, ”said Dr. Trey Dunbar, president of the hospital, the network.

In Oklahoma, where RSV cases have also risen sharply, hospital beds are becoming scarce.

“We’re just asking everyone to do their best to help a tense hospital situation,” an Oklahoma children’s hospital said in a Facebook post last week.

Dr. Cameron Mantor, the chief medical officer of Oklahoma Children’s Hospital at OU Health, told The Oklahoman that RSV cases in the state have remained “exponentially off the charts” in the past two months.

“RSV is a real problem right now,” he told the newspaper. “What will happen when we have an increase in pediatric Covid cases?”

The surge in RSV cases is due to the fact that new coronavirus infections in the United States rose 148 percent in the past two weeks and hospital admissions rose 73 percent, according to the New York Times.

The rise in coronavirus infections has been largely attributed to the highly contagious Delta variant and, in some states, to low vaccination rates.

“I am concerned if the children go back to school with the circulating delta we will see huge school breakouts that we have not seen in previous waves and disproportionately affect the children,” wrote Dr. Haq. “I’ve looked after hospital patients with Covid throughout the pandemic, but this time we’ll see more pediatric Covid shots with unvaccinated, susceptible children plus Delta variant.”

Texas Governor Greg Abbott has banned local governments and state agencies from prescribing vaccines and preventing local officials from requesting face masks.

Florida could face similar virus challenges early in the school year. Governor Ron DeSantis has spoken out against new masking recommendations from the CDC, and his office said in a statement last week that “parents know what is best for their children”.

Excess RSV infections have also been reported from places like New Zealand, which is currently winter. Experts there say children may be more susceptible than usual to seasonal viruses and infections because they were exposed to germs during lockdown at the beginning of the pandemic.

C.D.C. Inner Report Calls Delta Variant as Contagious as Chickenpox

C.D.C. Internal Report Calls Delta Variant as Contagious as Chickenpox

The Delta variant is much more contagious, is more likely to breach vaccine protection, and can cause more serious illness than any other known version of the virus, according to an internal presentation spread within the Centers for Disease Control and Prevention.

Dr. Rochelle P. Walensky, the agency’s director, admitted on Tuesday that vaccinated people with so-called breakthrough infections of the Delta variant carry just as much virus in their nose and throat as unvaccinated people and can spread it just as easily, albeit less often.

But the internal document sets out a broader and even more somber view of the variant.

The delta variant is more transmissible as the viruses that cause MERS, SARS, Ebola, the common cold, seasonal flu, and smallpox, and according to the document copied by the New York Times, it is as contagious as chickenpox.

The immediate next step for the agency is to “realize that the war has changed,” the document reads. The content was first reported by the Washington Post on Thursday evening.

The tone of the document echoes CDC scientists’ concern about the spread of Delta across the country, said a federal official who saw the research described in the document. The agency plans to publish further data on the variant on Friday.

“The CDC is very concerned about the incoming data that Delta is a very serious threat that requires action now,” the official said.

Coronavirus Pandemic and Life Expectancy in the United States

In the US, there were an average of 71,000 new cases a day as of Thursday. The new data suggests that vaccinated people spread the virus and contribute to these numbers – albeit likely to a far lesser extent than those who were not vaccinated.

Dr. Walensky has called transmission by vaccinated people a rare occurrence, but other scientists have suggested it is more common than previously thought.

The agency’s new masking guidelines for vaccinated individuals, introduced on Tuesday, were based on information contained in the document. The CDC recommended that vaccinated people wear masks indoors in public settings in communities with high virus transmission levels.

July 31, 2021 at 11:50 p.m. ET

However, the internal document indicates that even this recommendation may not go far enough. “In view of the higher transferability and current vaccination protection, universal masking is essential,” the document says.

The agency’s data suggests that people with weak immune systems should wear masks even in places with low virus transmission. This should include vaccinated Americans who are in contact with young children, older adults, or other vulnerable people.

According to the July 24 CDC quoted in the internal presentation, there are about 35,000 symptomatic infections per week among 162 million Americans vaccinated. However, the agency does not track all mild or asymptomatic infections, so the actual incidence may be higher.

Understand the state of vaccine mandates in the United States

Infection with the delta variant produces amounts of virus in the airways that are ten times higher than in people infected with the also highly contagious alpha variant, the document says.

According to a recent study, the amount of virus in a person infected with Delta is a thousand times higher than in people infected with the original version of the virus.

The CDC document draws on data from several studies, including an analysis of a recent Provincetown, Massachusetts outbreak that began in the city after the July 4th celebrations. By Thursday, that cluster had grown to 882 cases. About 74 percent had been vaccinated, said the local health authorities.

A detailed analysis of the prevalence of the cases showed that people infected with Delta carry enormous amounts of virus in their nose and throat regardless of vaccination status, according to the CDC document.

“This is one of the most impressive examples of citizen science I’ve seen,” said Dr. Celine Gounder, an infectious disease specialist at Bellevue Hospital Center in New York. “The people involved in the Provincetown outbreak meticulously created lists of their contacts and exposures.”

Infection with the Delta variant can be more likely to lead to serious illness, the document says. Studies from Canada and Scotland found that people infected with the variant were more likely to be hospitalized, while research in Singapore suggested that they were more likely to need oxygen.

Still, the CDC’s numbers show the vaccines are highly effective at preventing serious illness, hospitalization and death in people who have been vaccinated, experts said.

“Overall, Delta is the disturbing variant that we already knew it was,” said John Moore, a virologist at Weill Cornell Medicine in New York. “But the sky is not falling and vaccinations are still very protective against the worst of the consequences.”

Delta variant ‘completely’ driving Covid breakthrough circumstances, says physician

Delta variant ‘absolutely’ driving Covid breakthrough cases, says doctor

Professional sports leagues are uniquely positioned to track breakthrough Covid cases because they test thousands of athletes consistently, according to Dr. Robby Sikka, a physician who has worked with numerous NBA and NFL teams.

Sikka told CNBC that the highly transmissible delta variant is “absolutely” driving most of the Covid breakthrough cases he’s studied.

“Delta is driving this,” said Sikka, the founder of Sports Medicine Analytics Research Team, an organization that assists numerous professional sports leagues with injury data.

“We know that the delta variant has a higher viral load, it’s more infectious, it’s more contagious, and it is driving cases in the community. There’s an extremely high viral burden in the community.”

As Covid cases surge nationwide, new research is showing that fully vaccinated people can transmit the virus as asymptomatic carriers. More than 5,900 fully vaccinated Americans have either died or been hospitalized with Covid breakthrough infections through July 19, according to the Centers for Disease Control and Prevention’s most recent data. The website also notes that 1,821 of those cases were either “asymptomatic or not related to Covid-19.”

Sikka told “The News with Shepard Smith” that vaccines do work to prevent severe illness when it comes to Covid and the delta variant, and that a key takeaway from sports is that vaccinated athletes come back sooner than those who are unvaccinated. 

“The athletes that have gotten Covid, despite being vaccinated, by and large, returned and have done well and been able to return and perform at a high level,” said Sikka.

The Delta Variant Is the Symptom of a Larger Menace: Vaccine Refusal

The Delta Variant Is the Symptom of a Bigger Threat: Vaccine Refusal

Of the 39 percent of unvaccinated adults, around half say they are not vaccinated at all. But even within this group, some say they would do it if asked to.

Understand the state of vaccine mandates in the United States

Some are hesitant and may come with the right conviction from people they trust, while still others plan to get vaccinated but say they just didn’t stand a chance.

Politics is only a driver for some of these people, noted Dr. Richard Besser, a former director of the Centers for Disease Control and Prevention. In New Jersey, where he lives, rates fluctuate dramatically due to socio-economic factors. In the predominantly white Princeton, 75 percent of adults are vaccinated, compared to 45 percent in Trenton, only 22 kilometers away, which is very black and Latin American.

“Both are strong democratic areas so it’s really important to break things down and address the issues that are hindering vaccination progress in every segment of the unvaccinated population,” said Dr. Better.

However, there is no doubt that the political divide is playing a role in the rising infection rates. From the start, vaccinations in counties that voted for Donald J. Trump have lagged behind those in counties that voted for Joseph R. Biden, and the gap has only widened – from two percentage points in April to now almost 12 points, according to a recent survey by the Kaiser Family Foundation.

According to another poll nationwide, 86 percent of Democrats got at least one shot, compared with 52 percent of Republicans. Even the national goal of getting 70 percent of adults vaccinated by July 4th somehow became “Biden’s goal,” said Dr. Nahid Bhadelia, director of the Center for Emerging Infectious Diseases Policy and Research at Boston University.

“Suddenly, even getting out of the pandemic became a left-versus-right problem.”

As of May, fewer than half of Republicans in the House of Representatives are vaccinated, compared with 100 percent of Democrats in Congress. For months, several Republican lawmakers, including Senators Ron Johnson from Wisconsin and Rand Paul from Kentucky, as well as conservative news commentators like Tucker Carlson, have voiced their skepticism about vaccines.

Covid circumstances are rising once more in all 50 states throughout U.S. as delta variant tightens its grip

Covid cases are rising again in all 50 states across U.S. as delta variant tightens its grip

Covid cases are on the rise in all 50 states and the District of Columbia as the Delta variant spreads rapidly in the US and the virus once again tightens its grip.

The U.S. reports an average of about 43,700 new cases per day over the past week – well below pandemic highs but up 65% in the past seven days and nearly three times what it was two weeks ago, data compiled by Johns Hopkins University were indicates. Cases hit a 15-month low in late June before starting to rise again as fewer people were vaccinated and the more contagious Delta variant caught on in the country.

Vaccination rates peaked in April, at more than 3 million vaccinations per day, but have declined significantly in recent months to around 530,000 per day, according to data from the Centers for Disease Control and Prevention.

Louisiana, Arkansas, Missouri, Florida and Nevada reported the highest daily average of new cases per capita for the past week, all of which are at least twice the US rate.

Each of these states also have vaccination rates below statewide levels, with the largest gap visible in Louisiana, where 47.7% of the eligible population ages 12 and older received vaccination or more, compared with 65.9% across the country.

According to the Centers for Disease Control and Prevention, hospital admissions for Covid patients have increased by 32% compared to a week ago. The number of daily Covid deaths, which typically lag a few weeks or more behind a surge in case numbers, has increased, but not at the same pace as cases or hospitalizations. Many Americans who are most susceptible to the virus now also have some level of protection, with 89% of seniors having at least one vaccination.

“The death toll has not increased because we have done an incredible job to fully vaccinate the populations most likely to die from Covid-19, especially those over 65 and nursing home residents,” said Dr. Peter Chin-Hong, an infectious disease specialist at the University of California at San Francisco, said in an interview. “The deaths are also lagging behind the infection rate in some cases, but I also assume that the death rate will not change.”

The overwhelming majority of severe Covid cases – 97% of hospital admissions and 99.5% of Covid deaths – occur in those who are not vaccinated, U.S. surgeon general Vivek Murthy told reporters at a White House briefing Thursday .

President Joe Biden and CDC Director Dr. Rochelle Walensky have both described the current state of the outbreak as “a pandemic of the unvaccinated”.

US officials are urging Americans to get vaccinated against the Delta variant, which Walensky says is one of the most contagious respiratory diseases scientists have ever seen. With 68.6% of the adult population at least partially vaccinated, the US still hasn’t met Biden’s July fourth goal of 70% of Americans 18 years of age and older to receive one or more vaccinations.

The variant is highly contagious, mainly because people infected with the Delta strain can carry up to 1,000 times more virus in their nasal passages than those infected with the original strain, according to new data.

“The Delta variant is more aggressive and much more transmissible than previously circulating strains,” Walensky told reporters at a briefing Thursday. “It’s one of the most contagious respiratory viruses we know and that I’ve seen in my 20-year career.”

Local officials across the country are now asking Americans to return to wearing masks indoors. Several California and Nevada counties are now advising all residents to wear masks in public indoor spaces, regardless of whether they are vaccinated or not. Local leaders in at least three other states have reintroduced mask mandates, issued face-covering recommendations, or threatened the return of strict public health limits for all residents – despite CDC guidelines that vaccinated individuals do not use these protocols in most settings must follow.

“The easiest and best and most effective way to prevent a new variant from emerging and destroy the existing Delta variant is to get everyone vaccinated,” said Dr. White House Chief Medical Officer Anthony Fauci in an interview with CNBC on Wednesday.

How India is doing now after delta variant unfold

How India is doing now after delta variant spread

The Delta variant was first discovered in India last October and resulted in a massive second wave of Covid-19 cases in the country.

Since then, the highly contagious strain has spread around the world.

The variant has usurped the previously dominant alpha variant, which was first discovered in Great Britain last fall, and triggered further waves of infections in Europe and a threatening increase in cases in the USA

In fact, the delta variant now accounts for 83% of all sequenced cases in the US, the director of the US Centers for Disease Control and Prevention Rochelle Walensky said Tuesday, a dramatic 50% increase the week of July 3rd means.

The World Health Organization has already warned that due to the estimated transmission benefit of the Delta variant, “it is expected to quickly overtake other variants and become the dominant circulating line” in the coming months.

In its latest weekly report on Wednesday, the WHO found that the prevalence of Delta among the specimens sequenced in the past four weeks in many countries worldwide including Australia, Bangladesh, Botswana, China, Denmark, India, Indonesia, Israel, Portugal, Russia , Singapore, South Africa and the UK

But what about India, where the Delta variant first appeared in October?

The situation is still bad, data shows, but not as bad as it was when the second wave peaked in the country, when the daily new cases were above 400,000. On May 7, India reported a staggering 414,188 new infections and several thousand deaths.

Fortunately, cases have decreased significantly since then. On Thursday, India reported 41,383 new coronavirus infections and 507 new deaths, the Indian Ministry of Health tweeted the data.

The seven-day average of 38,548 new cases every day is a 3% decrease from the previous average, according to data from Johns Hopkins University and Our World in Data.

Meanwhile, the percentage change in the number of newly confirmed cases in the past seven days (compared to the number in the previous seven days) is sharp in parts of Europe and the United States.

In France, the percentage change in the number of new cases over the past seven days is 223% in France, 112% in Italy, while the percentage change in Germany is 50%. In the US, the percentage change over the past seven days is 58% higher than the previous seven-day period.

Nevertheless, according to data from Johns Hopkins University, India has the second highest number of registered Covid cases worldwide with over 31.2 million cases and almost 419,000 deaths, after the US.

During the first wave of the pandemic, India went into a nationwide lockdown in March 2020, which was only lifted in June last year with a series of easings over the following summer months.

However, when the second (and much tougher) wave hit in early 2021, Prime Minister Narendra Modi defied pressure to re-impose a national lockdown and left the responsibility to individual states as to whether they should reintroduce restrictions instead. A member of Modi’s economic advisory council defended the Modi government when it came under pressure in May, telling CNBC that state governments should have the final say on social restrictions.

Additionally, in order to tackle its Covid crisis, India has stopped exporting Covid vaccines (it makes a domestic version of AstraZeneca University Oxford called “Covishield”) and is not expected to resume exports until the end of the year the year.

Public health experts told the FT in late May that regional lockdowns, decreased social interaction and increasing levels of antibodies to Covid in the general population are helping to lower the infection rate in India. Vaccinations have also helped continue the downward trend in cases.

Exposure to Covid during the second wave was illustrated in the latest data showing the prevalence of antibodies to Covid in the general population.

A national blood serum poll that performed antibody tests (known as the Sero Poll) was released Tuesday and showed that two-thirds of the Indian population have antibodies to Covid, Reuters reported, although about 400 million of India’s 1.36 billion People did not have antibodies, the survey found.

Monitoring one of the largest vaccination campaigns in the world (India needs to vaccinate around a billion adults) is no easy task and the overall vaccination rate remains sluggish compared to other countries around the world.

Our World in Data figures show that 87.5 million people (around 6.3% of the total population, including children) are fully vaccinated, while 330.2 million people have received at least one dose of people who are fully vaccinated.

Inside together

On Tuesday, Modi expressed concern about a “significant” number of health care workers and frontline workers who have still not been vaccinated despite the vaccination program launched more than six months ago.

In a press release released by the government in which senior officials briefed on the Covid situation in India, Modi also spoke of the need to “remain vigilant about the situation in different countries,” noting that “mutations make this disease very unpredictable. and so we must all stand together and fight this disease. “

Chandrakant Lahariya, a New Delhi-based doctor who is also an expert on vaccines, public order and health systems, told CNBC that India is not out of the woods yet.

“The results of the fourth national sero survey … confirm what many had suspected: 67.6% of the total population and 62% of those who have not been vaccinated have developed antibodies (against Covid). Almost all age groups over 6 years have antibodies. This shows the extent of the virus spread in the second wave, “he noted.

“We know that [the] The vaccination rate is lower than expected and the Covid-compatible behavior is not optimal. With 400 million of the population still vulnerable, it would be like inviting the next wave ahead of time to abandon our vigilance. India needs to be fully prepared for each subsequent wave. What is happening in Indonesia, Vietnam or Great Britain is an alarm bell that no country can lose its vigilance and [that they] have to do everything in their arsenal, “he added.

The emergence of several significant varieties of concerns around the world (such as alpha, beta and delta), which then become widespread, “reaffirms how connected we are in this pandemic,” Lahariya continued.

“This is a reminder that we must view the challenges of a pandemic as one global community. It reminds us that we need all interventions and vaccine availability as our shared responsibility safe ‘must be repeated until it is understood at all levels, “he said.

Lahariya believed that more variants would emerge as the pandemic progressed. “We should be prepared for further variants until the pandemic is declared over.” Nobody knows where these variants will appear next.

Delta variant is without doubt one of the most infectious respiratory illnesses identified, CDC director says

Tennessee move to halt vaccine outreach to teens 'incredibly disturbing'

Rochelle Walensky, director of the CDC

The Delta-Covid variant is one of the most contagious respiratory diseases scientists have ever seen, the director of the Centers for Disease Control and Prevention said Thursday.

The variant is highly contagious, mainly because people infected with the Delta strain can carry up to 1,000 times more virus in their nasal passages than those infected with the original strain, according to new data.

“The Delta variant is more aggressive and much more transmissible than previously circulating strains,” said CDC Director Dr. Rochelle Walensky reporters at a briefing Thursday. “It’s one of the most contagious respiratory viruses we know and that I’ve seen in my 20-year career.”

The Delta variant has spread rapidly in the US and currently accounts for more than 83% of the cases sequenced in the US, up from 50% in the week of July 3rd.

The seven-day average of new cases has increased by around 53% compared to the previous week and is currently 37,674 new cases per day. Hospital admissions are up 32% to about 3,500 per day from last week, and deaths are up 19% to about 240 per day over the same period.

“This virus has no incentive to wear off and it remains on the lookout for the next person at risk to infect,” Walensky said.

The virus penetrates US counties with low vaccination rates, while counties with high vaccination rates have lower rates of new infections.

Three states, Florida, Texas and Missouri, with low vaccination rates account for 40% of all new cases nationwide, White House Covid Tsar Jeff Zients said. Florida alone accounted for one in five of all new cases in the United States for the second straight week.

In hospitals across the country, 97% of people admitted with Covid symptoms are unvaccinated, and 99.5% of all Covid deaths are also unvaccinated.

For the past week, the five states with the highest case numbers had higher rates of people getting re-vaccinated compared to the national average.

“We are at another pivotal moment in this pandemic as cases are picking up again and some hospitals are reaching capacity in some areas. We need to come together as a nation,” Walensky said.

Native officers throughout U.S. are beginning to reimpose masks guidelines as delta variant takes maintain

Local officials across U.S. are starting to reimpose mask rules as delta variant takes hold

From Los Angeles to Massachusetts, local officials across the country are urging Americans to wear masks again as the Delta variant rips across the US

Several California and Nevada counties are now advising all residents to wear masks in public indoor spaces, regardless of whether they are vaccinated or not. Local leaders in at least three other states have reintroduced mask mandates, issued face-covering recommendations, or threatened the return of strict public health limits for all residents – despite federal health guidelines that in most cases, vaccinated individuals do not use these protocols must follow the settings.

“A surge in the number of cases was not unexpected as the community began to reopen fully,” Jennifer Sizemore, spokeswoman for the southern Nevada health district, told CNBC in an email. Clark County, home of Las Vegas, tightened its mask recommendation last week after Covid-19 cases and deaths rose 50% in the previous week. A total of 4,599 new infections and 33 coronavirus-related deaths were reported last week, according to data from the Centers for Disease Control and Prevention.

Covid infections are rising again in the US after months of falling cases, new cases have risen 55% since last week to an average of 37,000 new cases per day in the past seven days, according to a CNBC analysis of data compiled by Johns Hopkins University .

The CDC relaxed its Covid guidelines on masks for fully vaccinated individuals on May 13, stating that they do not need to use them or practice social distancing in most environments. CDC director Dr. Rochelle Walensky told lawmakers at a Senate hearing Tuesday that the agency was actively reviewing its mask and other public health guidelines as the virus and pandemic evolve, especially as scientists learn more about the Delta variant and how it is doing Keep vaccines against it.

“A lot has changed since May 13,” said Walensky. “We now have a variant in circulation in this country that was 3% (of new cases) at the time and is now 83% and much more transferable.”

The Delta variant is spreading across the country, especially in areas with low vaccination rates, she said. Nearly two-thirds of counties in the US have vaccinated less than 40% of their residents, “which is what enables the emergence and rapid spread of the highly transmissible Delta variant,” leading to an increase in hospital admissions and deaths, she said.

This is gradually becoming apparent in Nevada, which, according to CDC data, has only fully vaccinated 43.5% of its population. Clark County recorded 641 new Covid hospital admissions last week, 23% more admissions than the previous seven days. Despite the resurgent outbreak in the Las Vegas area, Sizemore said the county’s vaccination rate has remained at just under 42% for the past two weeks.

“However, the community’s vaccination rate has slowed and unvaccinated people are not taking recommended precautions, including wearing masks and continuing to practice social distancing,” Sizemore said.

Nevada isn’t the only state that is stepping up its mask guidelines. On Friday, seven counties in California’s Bay Area recommended the use of masks indoors for a full mandate. The California city of Berkeley also called for the continued use of masks.

Further south, Los Angeles County restored its indoor public mask mandate on Saturday. The county initially lifted the mandate on Thursday when the state formally withdrew a number of executive measures to contain the spread of Covid.

White House senior medical advisor Dr. Anthony Fauci said Los Angeles County’s new mask mandate could serve as a prototype for other regions with high rates of infection. He said he expected schools and businesses to continue enforcing their own mask policies to protect against the Delta variant.

“If you want to be even more secure despite being vaccinated, you should wear a mask indoors, especially in crowded places,” Fauci said in an interview with CNBC’s Closing Bell. On Wednesday.

In Massachusetts, Provincetown officials advised everyone on Monday to resume wearing masks indoors after the July 4 celebrations resulted in an outbreak of new cases.

In Orleans Parish, Louisiana – where the CDC reported 560 new coronavirus cases last week – New Orleans Mayor LaToya Cantrell authorized a consultation on indoor masks on Wednesday to help curb the spread of the Delta variant. And New Jersey Governor Phil Murphy told CNBC’s Squawk Box on Tuesday that he wanted to avoid reinstating a mask mandate and instead press for residents to get vaccinated.

“Right now, I hope we don’t have to,” Murphy said. “If we have to, we will.”

CDC Says Delta Variant Makes Up an Estimated 83 % of US Circumstances

CDC Says Delta Variant Makes Up an Estimated 83 Percent of US Cases

The highly infectious Delta variant now accounts for an estimated 83 percent of new coronavirus cases in the United States — a “dramatic increase” from early July, when it crossed the 50 percent threshold to become the dominant variant in this country, the director of the Centers for Disease Control and Prevention said Tuesday.

In some regions, the percentage is even higher — particularly where vaccination rates are low, Dr. Rochelle Walensky, the C.D.C. director, said during a Senate health committee hearing. Two-dose vaccines have been shown to be effective against the Delta variant but questions have been raised about Johnson & Johnson’s single-dose regimen against Delta. While almost 60 percent of U.S. adults are fully vaccinated, less than half of the total U.S. population is.

She said the C.D.C. would update its website later Tuesday to reflect the new estimate of Delta cases, which the agency derives from gene sequencing of new coronavirus cases.

The new figure comes as new cases have been rising across the United States, though cases, hospitalizations and deaths remain a fraction of their peaks. Still, public health experts are watching the increases with deep concern and Dr. Walensky warned last week that “this is becoming a pandemic of the unvaccinated.” The seven-day average now shows nearly 38,000 new daily cases, up from about 11,000 a day not long ago, according to a New York Times database.

Tuesday’s hearing was contentious at times. Senator Mitt Romney, Republican of Utah, pressed Dr. Janet Woodcock, the acting commissioner of the Food and Drug Administration, on when the F.D.A. would authorize booster shots — and was not happy when she could not provide a specific answer. Federal health officials have said booster shots are not necessary now and have pressed Pfizer for more evidence.

Other Republicans clashed with witnesses over matters including mask mandates, booster shots for Covid-19 vaccines and “gain of function” research designed to identify genetic mutations that could make a virus more powerful.

Senator Rand Paul, Republican of Kentucky, escalated his long-running attacks on Dr. Anthony S. Fauci, President Biden’s top medical adviser for the coronavirus pandemic, and accused Dr. Fauci of committing a crime by lying to Congress in May when he told senators that the National Institutes of Health did not fund “gain of function” research at a laboratory in Wuhan, China, the epicenter of the pandemic’s early days.

Dr. Fauci, in turn, accused the senator of falsely implying that the N.I.H. is somehow responsible for hundreds of thousands of deaths from the pandemic — an extraordinary exchange for the Senate, where witnesses almost always defer to lawmakers.

“I have never lied before Congress and I do not retract that statement,” Dr. Fauci declared, adding, “Senator Paul, you do not know what you are talking about, quite frankly, and I want to say that officially.”

Is ‘Loki’ a True Marvel Variant? Or Only a Enjoyable Experiment?

Is ‘Loki’ a True Marvel Variant? Or Just a Fun Experiment?

One thing Marvel knows how to do is expand a story. Think back to the nascent days of the Marvel Cinematic Universe in the early ’00s. The so-called Phase 1 was about building out the superhero roster with individual film narratives that would dovetail into a big crossover movie: “The Avengers.” A decade and a half later, the crossovers are old hat, the Easter eggs are expected, and a spate of new movies and TV shows continue to provide an influx of stories and characters that branch off into their own universes.

You could even say the M.C.U. resembles a branching timeline — that’s what a member of the Time Variant Authority, or T.V.A., the bureaucracy at the center of the Disney+ series “Loki,” would say. Because for all the interdimensional fun the series has, “Loki,” which wrapped up last week, is a philosophical dialogue that also functions as a metacommentary on Marvel’s storytelling. The show’s central theme about the value of order versus chaos reflects how the M.C.U., as it expands across Disney+ and beyond, alternatively presents and breaks from contained, linear narratives and rote character types.

Although Loki (Tom Hiddleston), the sometime nemesis and sometime ally of the Avengers, was killed by Thanos in “Avengers: Infinity War,” the Asgardian now appears — resurrected! — in his own series. But it’s only a resurrection in a branding sense: The series centers on an earlier version of Loki, one who escapes the Battle of New York, from the first “Avengers” film, with the all-powerful glow-box (known as the Tesseract). His escape with the Tesseract causes a branch in the timeline, an offense that gets him first arrested by the T.V.A. and then recruited by one of the group’s agents, Mobius (Owen Wilson), to help catch a female “variant” Loki (Sophia Di Martino) who has been disregarding the rules of other timelines. In an inspired, if awkward, Freudian twist, the two Lokis fall for each other and team up to dismantle the T.V.A. before eventually finding themselves at odds.

From the beginning, “Loki” was an odd addition to the M.C.U. because it, like the recent “Black Widow” film, tried retroactively to give a back story and growth to a character who was already dead in the central M.C.U. timeline. More intriguing, it repositioned a character who had been an antagonist and a foil to Avengers like his adopted brother, the Norse golden boy Thor, as the hero of his own story, one that undermined what we had already seen happen in the franchise.

By making another version of Loki a hero, the series itself is acting as a variant. In general, Marvel has been using its latest Disney+ shows to deviate from the often wearying, even oppressive, timeline that the films have established. These side stories open up the world to more subtle, interesting narratives: “WandaVision” and “The Falcon and the Winter Soldier” allowed their heroes to develop in terms of both superhero abilities and emotional depth.

But whatever their divergences, these stories always end up leashed to the main M.C.U. narrative — Marvel’s own inviolable timeline, which often yields an awkward result. “WandaVision” used its classic TV parodies to cleverly explore the contours of grief and emotional escapism until its “Avengers” adjacency apparently demanded a requisite explosive ending. Sam Wilson (Falcon) and Bucky Barnes (the Winter Soldier) wrestled with trauma and its consequences, but the specter of Captain America, and the question of whether Sam would ultimately take up the shield, took over the story in the end.

In “Loki,” the Asgardian discovers that everything is predestined, even his identity. Loki is supposed to be a villain, and he is supposed to lose. There are no other options. What the series asks is, how does a character whose purpose is simply to accentuate, by way of contrast, the strengths and flaws of others, lead his own story?

The series certainly struggles to answer that question at first; Loki seems out of place in his own show. When the show allows him to be less of a reactionary character — he gets his own foils in the form of his many variants — he finally feels like the focus of the narrative. He evolves, proving that Loki can win and be honest and loving and compassionate. And just as “Loki” challenges how its title character is defined, so does the series break him out of the sole function he has served in the M.C.U. thus far.

As a loyal T.V.A. agent, Mobius, as he tells Loki, believes that his job is to maintain an ultimate sense of order — even if that order appears to rob the universe of free will. What happens when the timeline is all sorted out, without branches? “Just order, and we meet in peace at the end of time,” Mobius says.

“Only order? No chaos?” Loki responds. “That sounds boring.”

Marvel risks undercutting itself with “Loki” and with each bit of narrative chaos introduced by its latest shows. How can anything have emotional stakes when there is always a loophole or deus ex machina around the corner? (Indeed, “Loki” takes place in a closed loop, which by the series’s end has reset.) And at what point does narrative consistency fall apart and give us an indecipherable jumble of contradicting events?

The franchise wants to subscribe to both a traditional mode of storytelling and a bit of narrative chaos in the form of time travel, multiple universes and nonlinear shifts in time and space — all of which allow for deviations from the main story line. But the more variant stories we get, the more unstable and convoluted the whole structure becomes.

“Loki” is a fun touch of chaos for Loki fans, myself included, but it makes me wonder how much longer the relative order of the M.C.U. franchise’s central chronology can sustain the backpedaling and jumps and reversals, even within their own pockets of time. The vast megaverse that is Marvel already hosts countless characters and stories, and yet having one in which Loki is still alive is infinitely more fun.

But as delightful as “Loki” is conceptually, to me it felt like simply a fun, diverting experiment. What Marvel will do with the results of this experiment is another story. This season’s cliffhanger ending means that the full measure of the series’s success and impact is still to come, whether in the second season promised in the finale or in the broader M.C.U.

Is “Loki” truly a variant within the M.C.U.? Will it introduce reverberations throughout the films and TV shows going forward, or will it be essentially isolated in its own playful thought bubble? If the former, I suspect the Marvel won’t be able to sustain the full heft of the master narrative, with all of those branches, forever — that is, unless Marvel fully embraces chaos and lets the M.C.U. fracture into separate multiverses without such a restrictive overarching timeline. After all, if the god of mischief has taught us anything, it’s that a little bit of chaos can go a long way.
