The United Nations agency warned against issuing “immunity passports” or “risk-free certificates” to people who have been infected, saying the practice may actually increase the risk of spread as they may ignore standard advice
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 statement, the United Nations agency warned against issuing "immunity passports" or "risk-free certificates" to people who have been infected, saying the practice may actually increase the risk of spread as they may ignore standard advice.
Chile said last week it would begin handing out "health passports" to people deemed to have recovered from the illness. Once screened to determine if they have developed antibodies to make them immune to the virus, they could immediately rejoin the workforce.
The death toll from coronavirus or Covid-19, that believed to be originated from China's Wuhan, reached 197,703 globally as of Saturday. Besides, 2,837,463 cases were reported from around the world.
