A person who has recovered from COVID-19 is likely to be safe from relapse for three months, according to updated guidelines from the Centers for Disease Control and Prevention (CDC).
The information marks the first recognition of a certain period of immunity for people who have been cured of a COVID-19 infection.
Previous research has shown that antibodies from recovered patients will fade over several months, but federal scientists had not previously said what it means for immunity.
The CDC previously recommended that someone recovering from a COVID-19 infection do not need to be tested again for three months as long as that person is asymptomatic, but made it clear that any correlation with immunity was still unknown.
The CDC did not make an official announcement of the findings; rather, the information was included as part of the broader quarantine guidelines that was last updated earlier this month.
According to the agency, people who have been in close contact with someone who has COVID-19 should quarantine for 14 days, except people who have had COVID-19 within the last 3 months.
“People who test positive for COVID-19 do not need to quarantine or get tested again for up to 3 months as long as they do not show symptoms again. People who develop symptoms again within 3 months of their first COVID period. “19 may need to be tested again if there is no other cause identified for their symptoms,” the CDC said.
A CDC spokesman explained that while it is unlikely that anyone will recover or infect others during the three-month period, “it is important that these individuals continue to socially distance themselves, wear masks and practice good hand hygiene while scientists to know more about long-term immunity against COVID. “
