Biden tests positive for COVID for seventh day

• The 79-year-old president is fully vaccinated and received a second booster shot in March.

What they're saying: The president continues to feel "very well," Biden's doctor, Kevin O'Connor, wrote Friday.

• "His cough has almost completely resolved," O'Connor added.
• "His temperature, pulse, blood pressure, respiratory rate and oxygen saturation remain entirely normal. His lungs remain clear," O'Connor said.
• The doctor said Biden is continuing to follow "strict isolation measures," although he did speak at the Rose Garden on Friday.

For the record: The CDC says people can end their COVID isolation after five full days if they are fever-free for 24 hours without the use of fever-reducing medication and other symptoms have improved.

• Biden has continued to test positive on an antigen test.
• Antigen tests may remain positive for weeks to months after initial infection and may not always indicate contagiousness, according to the Centers for Disease Control and Prevention.

Be smart: "Rebound" cases of COVID-19 are possible for those who take Paxlovid, but it remains relatively rare, according to a Mayo Clinic study released in June.

• "Paxlovid continues to be recommended for early stage treatment of mild to moderate COVID-19 among persons at high risk for progression to severe disease," the CDC said in May.
