The World Health Organization (WHO) expressed concern that not all people who recovered from coronavirus may obtain immunity to Covid-19. Their organisms may not have antibodies for the fight against the second infection with this virus, as CNBC reported citing Dr. Mike Ryan, the executive director of WHO’s emergency program.

“With regards to recovery and then reinfection, I believe we do not have the answers to that. That is unknown. There are many reasons why we might see the reactivation of infection either with the same infection or another infectious agent. There are many situations in viral infection where someone doesn’t clear the virus entirely from their system,” Ryan stated.

According to him, some patients can clear the main infection but they can have a secondary bacterial infection.

The preliminary research in Shanghai showed that some patients do not have antibodies, while others had a high immunity response.

“Whether the patients who had a strong antibody response were immune to a second infection is a separate question,” WHO’s scientist on Covid-19, Dr. Maria Van Kerkhove said.

The WHO officials noted that over 300,000 out of 1.87 million infected people recovered but they need more data about recovered patients to understand the response of their antibodies, whether they obtain immunity and for how long.

U.S. Centers for Disease Control and Prevention develop a test for detection of the presence of the antibodies to coronavirus to establish whether a person might be protected from the disease. According to the WHO, such a test may define who was affected by a virus but it is unclear whether it will identify people who are reinfected.

Meanwhile, in Ukraine, the number of coronavirus cases has increased by 270: the total number of infected persons is 3,372.
