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

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.

Infectious illness knowledgeable says Covid vaccine misinformation is ‘killing individuals’

Dr. Nahid Bhadelia, founding director of the Center for Emerging Infectious Diseases at Boston University, expressed concern about the spread of misinformation about Covid vaccines on social media.

“I think social media plays a huge role in amplifying misinformation that is leading people not to take the vaccine, which is killing them,” Bhadelia told CNBC on Friday. “It’s the honest truth. Covid is a vaccine-preventable disease at the moment.”

President Joe Biden said Friday that platforms like Facebook are killing people by allowing misinformation about Covid-19 vaccines through their services. He went back those comments on Monday, mainly accusing the platform’s users of sharing misinformation.

Bhadelia cited results from the Kaiser Family Fund poll, which found that 54% of Americans either believe or cannot tell whether a common Covid vaccine myth is fact or fiction.

The US is struggling with a drop in vaccination rates and an increase in infections. All 50 states have reported an increase in Covid cases over the past week, according to Johns Hopkins University. The US has an average of more than 26,000 new cases a day, and that’s the highest number in two months, according to Johns Hopkins.

Bhadelia told CNBC The News with Shepard Smith that she believes social media companies can do a lot more to stop the spread of disinformation.

“You have to invest a lot more resources and improve your balance to clear that information faster, invest more resources in changing your matrix, because right now what is on top of your page is not right, but what it is is popular, “said Bhadelia, a medical worker for NBC News.

She also suggested that social media companies should partner with public health officials more to get the right information out to the people.

Facebook spoke out against the White House claims.

“We will not be distracted by allegations that are not supported by the facts,” said a spokesman. “The fact is, more than 2 billion people have viewed authoritative information about COVID-19 and vaccines on Facebook, more than any other place on the internet. More than 3.3 million Americans have also used our vaccine finder tool to find out where and how to get a vaccine. The facts show that Facebook helps save lives. Point.”

The second dose of Covid vaccine is required for full immunity, infectious illness specialist says

According to Dr. Paul Offit, director of the Vaccine Education Center at Philadelphia Children’s Hospital, the second dose of the Covid-19 vaccine is critical to creating longer and complete immunity as well as preventing variants of the virus.

“We need to know that this is a two-dose vaccine,” Offit told CNBC’s The News with Shepard Smith. “The second dose of the Pfizer or Modern vaccine increases it dramatically, inducing the type of cells that suggest you have longer long-term memory, which means the vaccine would last a few years. I think when we have humans Getting only one dose of the vaccine that gives you shorter and less complete immunity will only lead to variants. “

His comments came after a recent study suggested that the second shot of the Pfizer vaccine could be delayed as the first offered high protection, according to a letter published in the New England Journal of Medicine.

To date, more than 15 million people in the US have received both shots of a two-dose Covid vaccine, according to the Centers for Disease Control and Prevention. Almost 25 million additional people in the country have received their first vaccination shot.

Moderna said last month that it plans to test a booster shot of its Covid vaccine a year after the first two-dose immunization.

“If you get a booster shot of this virus, which is the most common virus in circulation and produces more cross-reactive antibodies … you don’t necessarily have to load up with another vaccine when a variant reaches the point of being completely resistant to immunity, then we have to develop the second generation vaccine, “said Offit. “Right now it could mean a booster shot of the vaccines we’ve already made.”

Maryland confirms case of South African Covid variant that is extra infectious

Maryland has reported a case of the new, highly transmittable variant of Covid-19, which was first found in South Africa. This is the third case discovered in the United States, Governor Larry Hogan announced on Saturday.

The case involves an adult resident who lives in the Baltimore area and has not taken any international travel in the past. Maryland health officials and the United States Centers for Disease Control and Prevention have confirmed this.

“We strongly encourage Marylanders to exercise particular caution to limit the additional risk of transmission associated with this variant,” said Hogan. “Please continue to practice normal health and safety precautions, including wearing masks, regular hand washing, and physical distancing.”

The first two U.S. cases of the South African variant, known as B.1.351, were identified in South Carolina on January 28. Other variants found in the US come from the UK and Brazil.

The variants do not appear to cause more serious illness or an increased risk of death, but are considered highly contagious. Health officials are particularly concerned about variant B.1.351 as preliminary research suggests that vaccines may be less effective at controlling it.

President Joe Biden signed a travel ban last week on most non-US citizens who recently entered South Africa and re-introduced travel restrictions on non-US citizens from the UK and Brazil.

According to data from Johns Hopkins University, the virus has infected more than 25.9 million people and killed at least 436,000 people in the United States since the pandemic began.
