For those without symptoms, CDC guidance states they are considered contagious at least two days before their positive test.

The CDC states that anyone who may have been exposed to someone with COVID should test five days after their exposure, or as soon as symptoms occur.

"If symptoms occur, individuals should immediately quarantine until a negative test confirms symptoms are not attributable to COVID-19," the guidance states.

Ngozi Ezike said that incubation times could be changing, but those who test early should continue testing even if they get negative results.

But you know, if you want to test at two days, but that negative test...

According to earlier CDC guidance, COVID symptoms can appear anywhere from two to 14 days after someone is exposed to the virus.

Those who have been within six feet of someone with COVID for a cumulative total of at least 15 minutes over a 24-hour period should quarantine for five days if unvaccinated, or if they are more than six months out from their second vaccine dose, according to updated CDC guidance issued Monday.

Previously, the CDC said people who were not fully vaccinated and who came in close contact with an infected person should stay home for at least 10 days.

People who are positive for COVID should stay home for five days, the CDC said Monday, changing guidance from the previously recommended 10 days.

If you still have symptoms after isolating for five days, stay home until you feel better and then start your five days of wearing a mask at all times.

For those who test positive for COVID but have no symptoms, day 0 is the day of the positive test.

Treat a positive as a positive, stay home and isolate for five days."
