COVID-19 Infection Gives Some Immunity For At Least Five Months, UK Study Finds

News 18  

People who have had COVID-19 are highly likely to have immunity to it for at least five months but there is evidence that those with antibodies may still be able to carry and spread the virus, a UK study of healthcare workers has found. Preliminary findings by scientists at Public Health England showed that reinfections in people who have COVID-19 antibodies from a past infection are rare with only 44 cases found among 6,614 previously infected people in the study. They also warned that people with so-called “natural immunity” acquired through having had the infection may still be able carry the SARS-CoV-2 coronavirus in their nose and throat, and could unwittingly pass it on. But they warned that early evidence from the next stage of the study already suggests some people with immunity can still carry high levels of virus and could transmit it to others.
