World Health Organization (WHO) officials said that not all people who retrieve from the COVID-19 have the antibodies to fight a second infection from coronavirus. This raised concern that patients may not maintain immunity after extant coronavirus.
Dr. Mike Ryan, executive director of the World Health Organization WHO’s emergency program, said at a press conference on Monday at the WHO’s Geneva headquarters that regards to recovery & then reinfection to COVID-19, I believe we do not have the answers to that. That is still unknown.
Dr. Maria Van Kerkhove, WHO’s lead scientist said that an exploratory study of patients in Shanghai found that many patients had “no measurable immune system response” while others had a very high response on COVID-19.
World Health Organization (WHO) officials said that more than 300,000 of the 1.87 million COVID-19 cases all over the world have recovered. Van Kerkhove said added that they need more data from recovered patients to know their antibody response, whether that gives them immunity & for how long.
WHO officials Ryan told during the press conference on Monday at the WHO’s Geneva headquarters that there are questions about whether the coronavirus can reactivate after a patient recovers & tests negative for COVID-19 outbreak.
The United States Centers for Disease Control & Prevention has already declared that they are going to develop a test kit to expose the presence of COVID19 antibodies to determine if a person could be immune to the disease. While such a test can know who has been exposed to the COVID-19, it’s not clear if it can analyze those immune to reinfection.
World Health Organization officials also warned during the press conference on Monday that lifting social distancing restrictions & reopening businesses could lead to severe bad impacts. Earlier US President Donald Trump & New York Gov. Andrew Cuomo, have said they hope to reopen businesses as soon as it is safe to do so.
