Paxlovid

Paxlovid has been highly effective at reducing the risks of hospitalization and death, but some patients report a "Paxlovid rebound," in which the disease returns.

Paxlovid has been shown to curb the worst effects of COVID-19 but it has to be started within five days of symptoms. Previously, only doctors could prescribe it.

The White House announced more steps to make the treatment more accessible across the U.S. as it projects COVID-19 infections will continue to spread over the summer travel season.

In the past several months, new treatments have emerged, which are most effective within the first five days of symptoms but patients may have a hard time knowing whether they qualify.

Doctors have begun reporting cases of patients who see their symptoms return several days after treatment.
