Scientists and clinicians from all over the world are doing research to see if someone who had Covid-19 can get reinfected, Maria Van Kerkhove, the World Health Organization’s technical lead for coronavirus response and head of the emerging diseases and zoonoses unit, said Friday.
“What we understand from people who are infected with the SARS-CoV-2 virus, the virus that causes Covid-19, is that they will develop an immune response. They will develop antibodies, neutralizing antibodies, and an immune response that will provide some protection against reinfection,” Van Kerkhove said during a media briefing.
“What we don’t know right is how strong that protection is and for how long that protection will last. And we need answers to those questions to be able to determine if someone can be reinfected after that immunity wears off. So this is an area of active, active research for the specific SARS-CoV-2,” she said.
