No Evidence Recovered Patients Are Protected from Coronavirus

TEHRAN (IQNA) – The World Health Organization (WHO) said 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, Reuters reported.

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 coronavirus has infected more than 2.8 million and killed nearly 198,000 people worldwide.
