Hong Kong received its first COVID-19 reinfected case. Based on the results, researchers concluded that some of the recovered COVID-19 patients might have only short-lived immunity from the novel coronavirus, which caused the current global pandemic.
Previous studies about corona virus antibodies found that their levels reduce after a few months, suggesting that any potential virus immunity may not last long. Dr. Anthony Fauci, the head of the National Institute of Allergy and Infectious Diseases and the United States' top infectious disease expert, explained that immunity to other known corona viruses usually lasts only three to six months.
"It may be completely different with this coronavirus," he said.
"It may be that people induce a response that's quite durable. But if it acts like common corona viruses, it likely is not going to be a very long duration of immunity," he further explained.
