The research study, part of a major staff screening program, covered a 30-week duration between April and November 2020. Its outcomes have not peer-reviewed by other researchers however were published before evaluation on the MedRxiv site.
Separated cases of re-infection with COVID-19, the illness brought on by the SARS-CoV-2 infection, had raised issues that immunity may be short-lived which recuperated patients might swiftly fall ill once again.
LONDON, Nov 20 (Reuters) – People whove had COVID-19 are highly unlikely to contract it again for a minimum of 6 months after their first infection, according to a British research study of health care workers on the frontline of fight versus the coronavirus pandemic.
” Being infected with COVID-19 does use defense agains tre-infection for many people for at least 6 months,” Eyre said. “We discovered no brand-new symptomatic infections in any of the participants who had actually evaluated positive for antibodies.”
Staff with antibodies were likewise less likely to evaluate positive for COVID-19 without signs, the scientists said, with 76without antibodies testing favorable, compared to just three with antibodies. Those 3 were all well and did not developCOVID-19 symptoms, they added.
During the research study, 89 of 11,052 personnel without antibodies established a new infection with symptoms, while none of the 1,246 personnel with antibodies established a symptomatic infection.
The findings need to provide some reassurance for the more than 51 million people worldwide who have been infected with the pandemic disease, researchers at the University of Oxford stated.
” This is actually excellent news, because we can be positive that, at least in the brief term, a lot of individuals who get COVID-19 wont get it once again,” said David Eyre, a professor at Oxfords Nuffield Department of Population Health, who co-led the study.
However the results of this research study, performed in a friend of UK healthcare employees – who are among those at highest risk of contracting COVID-19 – recommend cases of reinfection are most likely to stay exceptionally unusual.
” We will continue to follow this cohort of personnel thoroughly to see how long protection lasts and whether previous infection affects the seriousness of infection if individuals do get infected once again,” Eyre said.
