Jakarta, CNN Indonesia – World Health Organization (WHO) confirms people who have recovered from Covid-19 you don’t necessarily have immunity or immunity.
WHO chief epidemiologist Maria van Kerkhove said there was no evidence that someone who had been infected with the coronavirus could no longer be infected.
The statement was in response to the purchase of 3.5 million serological test kits by the British government to measure levels of antibodies to Covid-19 in blood plasma.
“Currently, we have no evidence that the use of serological tests can show that a person has immunity or is protected against reinfection,” said Kerkhove.
Many of the tests developed are blood tests that are similar to instant HIV tests and measure elevated levels of antibodies that the body uses to fight viruses.
“This antibody test will be able to measure the level of seroprevalence or the levels of antibodies against pathogens in the blood. However, that does not mean that someone with antibodies means they are immune,” said Kerkhove.

Reporting from Sky newsKerkhove said there were many countries that suggested using rapid diagnostic serology tests to help identify what they thought would be a measure of immunity.
Kerkhove said the number of tests being developed was really good, but said these tests needed to be validated to provide clarity on the indicators measured in the tests.
“What this test will do will measure the level of antibodies. This test measures the response the body has one or two weeks after being infected with this virus,” Kerkhove said. CNBC.
WHO Executive Director of Emergencies Mike Ryan explains that scientists are still determining how long the antibodies form in the human body after being infected with the Covid-19 virus.
“No one is sure if someone with antibodies is fully protected from the disease or if they have been exposed again. Also, some tests have sensitivity problems,” Ryan said.
WHO officials say that not everyone who recovers from Covid-19 has antibodies to fight a second infection. This raises concerns that patients will not develop immunity or antibodies after recovering from Covid-19.
“Regarding recovery and then reinfection, I think we don’t have an answer for that. That is unknown,” Ryan said Monday.
A preliminary study of patients in Shanghai found that some patients “did not have a detectable antibody response” while others had very high responses. (jnp / dea)
