WHO officials say it's unclear whether recovered coronavirus patients are immune to second infection
According to the Johns Hopkins University COVID-19 dashboard , as of April 14, 2020, at 9:25, the number of infected people was 1,918,855 and the death toll was 119,588 worldwide.
According to the dashboard, there are 448,998 recovered people, but Dr. Mike Ryan, executive director of the emergency program at WHO, said, `` People who recovered from COVID-19 may be reinfected The answer to that question is 'unknown' for now, 'he said, saying that it's not safe to recover.
The other day, a team from Fudan University, China, announced that a third of those who recovered from COVID-19 had low antibody levels and some did not have a detectable antibody response. It was. Although the team prefaced it as 'not peer-reviewed,' WHO's Dr. Maria Funkirkhoffe said, 'It suggests that different patients have different levels of immunity.' Even if some people showed a strong antibody response, he said, 'It is another matter whether the antibody response actually means immunity.'

According to Dr. Ryan, many cases of COVID-19 are of a complex nature, which may lead to new infections or SARS-CoV-2 remaining in the body, depending on the patient's underlying illness and immune response. There is a possibility that he may get sick again because he is alive.
Secretary-General Tedros said that the cause of COVID-19, SARS-CoV-2, is 10 times more deadly than the 2009 pandemic pandemic influenza (H1N1) pandemic, and he was infected with the virus. While the number of employees has doubled every 3 to 4 days in some countries, the deceleration is at a very slow pace, and thus the lifting of restrictions such as suspension of business and refraining from going out is also slow. It should be a good thing, he said.
In addition, it does not mean that a vaccine cannot be made because immunity cannot be obtained, and virus experts have proposed the idea of making a live vaccine using a variant with low pathogenicity.
