Rev. Jesse Jackson has been transferred to a rehab center in Chicago following his hospitalization for a breakthrough Covid-19 infection.
The civil rights leader will receive physical therapy following treatment for the coronavirus at Northwestern Memorial Hospital in Chicago.
His wife, Jacqueline, was moved to an intensive care unit (ICU) at Northwestern, after her condition worsened.
Last week the couple's son, Jonathan, said his mother was "resting comfortably and responding positively to treatment."
Jonathan Jackson said Mrs. Jackson was on supplemental oxygen and was breathing easier.
However, her condition deteriorated over the weekend and she was moved to the ICU, according to DailyMail.com.
Jonathan said his mother is not on a ventilator but she is receiving "increased oxygen" in the ICU.
"Both of our parents are continuing to receive excellent medical care," he said. "We urge that you continue to keep them in your prayers because we know this is a serious disease."
Jesse Jackson, 79, and Jacqueline Jackson, 77, fell ill on August 20 and were taken to Northwestern where they both tested positive for Covid-19.
Jesse Jackson is fully vaccinated, but Jacqueline declined to take the vaccines for personal reasons. They were both admitted to the hospital on August 21.
