WHO: No evidence patients who recover from COVID-19 can’t get reinfected

Geneva: The UN World Health Organization (WHO) has warned that there is currently no evidence that people who have recovered from COVID-19 and have antibodies are protected from a second infection.
In a scientific brief issued on Friday, WHO said there was no proof that one-time infection could lead to immunity, and “laboratory tests that detect antibodies to SARS-CoV-2 [the virus that causes COVID-19] in people…need further validation to determine their accuracy and reliability.”
“At this point in the pandemic, there is not enough evidence about the effectiveness of antibody-mediated immunity to guarantee the accuracy of an ‘immunity passport’ or ‘risk-free certificate,’” the UN health agency warned.
“People who assume that they are immune to a second infection because they have received a positive test result may ignore public health advice. The use of such certificates may therefore increase the risks of continued transmission,” it added.
As part of its guidance on adjusting public health and social measures for the next phase of the COVID-19 response, WHO stressed that it continues to review the evidence on antibody responses to SARS-CoV-2 infection.
