US President Joe Biden continues to “improve significantly” despite a lingering sore throat from his coronavirus infection, his doctor said in an update on Sunday, according to The Associated Press.

“The president is responding to therapy as expected,” wrote Dr. Kevin O’Connor in his latest note. Biden has been taking Paxlovid, an antiviral drug developed by Pfizer that helps reduce the chance of severe illness.

O’Connor wrote that Biden still has a sore throat, though other symptoms, including a cough, runny nose and body aches, “have diminished considerably.”

Biden tested positive for COVID-19 on Thursday morning. O’Connor said Saturday that the president likely became infected with a highly contagious variant, known as BA.5, that is spreading throughout the country.

The White House has not released any photos or video of Biden since Friday, when the media watched him participate in a virtual meeting with economic advisers.

Several top US officials have tested positive for the virus in recent months. In June, US Ambassador to the United Nations Linda Thomas-Greenfield tested positive for the virus.

Earlier that week, US National Security Adviser Jake Sullivan tested positive for COVID-19. A National Security Council spokesperson said Sullivan is asymptomatic and he has not been in close contact with the President.

The previous month, US Health Secretary Xavier Becerra tested positive for COVID-19, but he too was not considered a close contact of President Biden.

US Secretary of State Anthony Blinken tested positive for COVID-19 two weeks before that and was said to be experiencing only mild symptoms.

A week earlier, Vice President Kamala Harris tested positive for the virus. Several days later, White House communications director Kate Bedingfield also tested positive for the virus and said she was only experiencing mild symptoms.

In late September, State Department spokesperson Ned Price tested positive for COVID-19 after experiencing symptoms.
