'No evidence' that recovered Covid-19 patients cannot be reinfected: WHO

The World Health Organization (WHO) said on Saturday that there was currently “no evidence” that people who have recovered from COVID-19 and have antibodies are protected from a second coronavirus infection.

In a scientific brief, the UN agency warned governments against issuing “immunity passports” or “risk-free certificates” to people who have been infected as their accuracy could not be guaranteed.“Some governments have suggested that the detection of antibodies to the SARS-CoV-2, the virus that causes COVID-19, could serve as the basis for an ‘immunity passport’ or ‘risk-free certificate’ that would enable individuals to travel or to return to work assuming that they are protected against re-infection,” the WHO said.
