The Chinese government has conducted serological tests on them in recent months, but a third of them have already died or refused to be tested, the WHO investigation team said. The serum test is a test to check the presence or absence of antibodies generated in the body when suffering from Corona 19.
Although all of the patients who responded to the test were negative, experts explained that it cannot be concluded that they have never had Corona 19. More than a year after they became ill, the antibodies may have decreased to undetectable levels.
The WHO investigative team called on the Chinese government to do more extensive serological testing of blood samples collected in Hubei Province in the fall of 2019, saying “more research is needed.” In response, the Chinese government replied that it had not obtained permission for serological testing of many samples stored in blood banks.
Professor Liang Wannian (梁萬年) Tsinghua University, who participated in the WHO investigation as a panel of Chinese experts, said that after examining medical records and blood samples obtained from 233 medical institutions in Hubei Province, there was no evidence that the virus had spread before December 2019. did.
