Rev. Jesse Jackson and his wife Jacqueline were hospitalized after testing positive for Covid-19, Mr Jackson’s Rainbow PUSH coalition said in a statement on Saturday.

Both were treated at Northwestern Memorial Hospital in Chicago, The Associated Press reported.

“Doctors are currently monitoring the condition of both,” the statement said. No details were given about their condition. Mr. Jackson is 79 and Jacqueline Jackson is 77.

Mr. Jackson was vaccinated in January. He has worked to convince more black Americans to get vaccinated.

“Vaccination is essential to save lives, especially for African Americans, who are disproportionately the greatest victims of the virus,” he said at the time.

He announced in 2017 that he was diagnosed with Parkinson’s.

A civil rights advocate for more than 50 years, Mr. Jackson competed for the Democratic presidential nominations in 1984 and 1988. He was a close associate of Rev. Dr. Martin Luther King Jr.
