People infected with the coronavirus once are likely protected against reinfection for at least nine months, if not longer, according to a new study.
Research data published Thursday by Lancet Healthy Longevity showed that long-term care facility residents who tested positive for coronavirus antibodies were 85% less likely to get the virus again, and staffers had a 60% lower risk, CNN reported.
The study, conducted by a team at University College London and other UK-based institutions, monitored 682 residents and 1,429 staff members from long-term care facilities in England between October and February, CNN reported. Some residents and staff were thought to have had the virus in the past because of antibodies found in blood samples from between June and November.
Residents testing negative for antibodies, the study said, found 93 out of 456 — or 20% — later tested positive for COVID-19 infections. However, only 2% of residents who tested positive for antibodies later tested positive for the virus.
Additionally, 11% of staff members who tested negative for antibodies later got the coronavirus during the study, compared to only 2% of those who tested positive for antibodies.
