One can be infected with COVID-19 again after getting cured for the first time, warns World Health Organization on Saturday.

In a statement by WHO said there is currently no evidence that people who have recovered from COVID-19 and have anti-bodies are protected from a second infection.

The WHO guidance came after some governments suggested that people who have anti-bodies to the coronavirus could be issued an ‘immunity passport’ or ‘risk-free certificate’ that would allow them to travel or return to work, based on the assumption that they were safe from re-infection, according to the statement.

People issued such a certificate could ignore public-health guidance, increasing the risk of the disease spreading further, according to reports.

While many countries are currently testing for anti-bodies, these studies aren’t designed to determine whether people recovered from the disease acquire immunity, the WHO stated.
