How many days does immunity against Corona last after the first infection?

A recent study found that infection with the Corona virus "Covid-19" provides some immunity for a certain period of time, so how much is it?

And during which, will people continue to carry and transmit the virus?

The study was conducted by the Public Health Authority of England (PHE), and included 6,614 participants who had tested positive for corona antibodies (that is, they had been infected).

It is published on the GoV Dot UK website (GOV.UK).

The researchers found that infection with the Corona virus "Covid-19" provides some immunity for at least 5 months, or 150 days, but people may continue to carry the virus and transmit it.

Experts have warned that people with immunity may still be able to carry the virus in the nose and throat, so there is a risk of transmitting it to others.

The scientists concluded that the naturally acquired immunity as a result of a previous infection provides 83% protection against re-infection, compared to people who have not had the disease before.

This appears to last for at least 5 months from the onset of the disease.

Warning

Public Health England (PHE) also warned that although people with antibodies had some protection from contracting COVID-19, early evidence from the next phase of the study indicated that some of these individuals carry high levels of The virus and they may continue to transmit the virus to others.

That is why it is important for everyone to continue to follow the rules and stay at home, even if they have previously had COVID-19, the researchers said.

Professor Susan Hopkins, chief medical advisor at Public Health England, said, "This study gave us the clearest picture yet of the nature of antibody protection against Covid-19, but it is important that people do not misunderstand these early results."

"We now know that most of those who contracted the virus, and developed antibodies, are protected from reinfection, but this is not completely and we do not yet know the duration of protection. Crucially, we believe that people may still be able to transmit the virus," she added.

Save lives

Hopkins said, "This means that even if you think you already have the disease and are protected, you can rest assured that you are unlikely to get a severe infection but there is still a risk that you will become infected and pass on to others. Now more than ever, from It is essential that we all stay at home to protect our health services and save lives. "

The statement said that the study will continue to follow the participants for 12 months to explore how long immunity may last, the effectiveness of vaccines and the ability of people who have immunity to carry and transmit the virus.
