Biden’s positive case caused the White House to cancel — so far — planned trips to Pennsylvania and Florida, two key battlegrounds. Biden has sought to get out on the road more since the beginning of the year, but his plans for domestic travel have also been limited by foreign trips and his focus on the Russian war in Ukraine.

It’s unclear precisely how long Biden, who is experiencing mild symptoms, will stay isolated.

The White House said that Biden will remain in isolation for at least five days and stay away from people until receiving a negative coronavirus test. That means he could resume in-person activities as early as Wednesday.

Centers for Disease Control and Prevention (CDC) guidelines call for a 10-day quarantine, but they say that individuals can shorten that quarantine to as few as five days if the patient is asymptomatic. Those who come out of isolation early are told to wear face masks.
