Coronavirus: No evidence survivors have immunity against virus — WHO

Epidemiologists at WHO said there is no evidence someone who has been infected cannot be infected again.

A senior epidemiologist at WHO, Maria van Kerkhove, at a virtual news briefing on COVID-19 said antibodies’ test will help measure the level of antibodies in the blood, but “that does not mean that somebody with antibodies means that they are immune,” she said.

She also said many tests for the ailment being developed are pinprick blood tests similar to instant HIV tests.

“There are a lot of countries that are suggesting using rapid diagnostic serological tests to be able to capture what they think will be a measure of immunity.

“Right now, we have no evidence that the use of a serological test can show that an individual has immunity or is protected from reinfection,” she said.
