Through meticulous research, the Centers for Disease Control and Prevention (CDC) has the most precise picture to date of what a person who has recovered from Covid-19 can expect.

Prior research has shown antibodies from recovered patients will fade over the course of a few months, but federal scientists had not previously said what that means for immunity.
The CDC previously recommended that someone recovered from a COVID-19 infection doesn’t need to be tested again for three months so long as that person is asymptomatic, but made clear that any correlation to immunity was still unknown.
The CDC did not make a formal announcement of the findings; rather, the information was included as part of broader guidance about quarantining that was last updated earlier this month.
According to the agency, people who have been in close contact with someone who has COVID-19 need to quarantine for 14 days, except people who have had COVID-19 within the past 3 months.
