Under the new coronary virus epidemic, it has implemented different degrees of cities in many countries. How to gradually restart the economy under the epidemic has become a top priority.Multi -nations are studying through antibody detection to allow people with immune proof to resume work early.Ficki, director of the National Institute of Allergies and Infectious Diseases, also stated last Friday (10th) that Washington is studying multiple plans, including possible to promote extensive antibody testing and prepare for restarting economic activities.However, experts have pointed out that there are many unknown numbers at the current new crown virus, which has doubts the results of antibody detection.
Anthony FAUCI was interviewed by the United States CNN last Friday. When asked if Washington would issue an immune certificate to people with new crown virus antibodies, he said it was possible.He further stated that the implementation of antibody detection nationwide is one of the multiple programs that are currently discussed.He said that it is important to consider restarting economic activities to understand the degree of virus infiltration society.The Food and Drug Administration (FDA) for the first time earlier this month, a blood test for detecting the new coronary virus antibody was awarded emergency authorization. The National Institute of Health also announced on Friday that it would test for 10,000 healthy volunteers.The fastest expected weekly, there will be a large number of detection for public use, but emphasizing that experts will not ignore virus testing, and the two will be carried out simultaneously.
Test serum testing of beautiful 10,000 health
The principle of serotics testing is to find an antibody in the blood of the subject to find out whether he has been infected and has a certain level of immunity.This helps the government to arrange immunohisties to take the lead in re -work, or allow the hospital to be able to allocate people's hands more effectively according to the risk of infection.Germany has begun trial antibody testing. For example, the research team of the University of Bonn was tested for 1,000 people in the northwestern town with a serious epidemic.After eliminating the overlapping case, the team estimated that 15%of the residents in the town had infected the virus.The Wall Street Journal said that officials in the United Kingdom, Italy, and France also discussed the issuance of immune cards.
Virus strains or mutant old antibodies may not be effective
However, the effectiveness of antibody detection is questioned. For example, unknown whether its virus strains will continue to mutate like seasonal influenza, the existing antibody may not be effective for the new virus strains, and some types of antibodies will also weaken over time.In Wednesday, Wednesday was interviewed by the editor -in -chief of the American Medical Society Journal, HOWARD BAUCHNER, and believed that the new crown virus seemed to have not deteriorated so far. It is estimated that those who recovered after the infection in February to March may be from September to October.Still immune.However, a preliminary study of Shanghai Fudan University has not been reviewed by peers that the level of antibodies in some recovery people may not be enough to prevent second -degree infection.The research team analyzed the blood samples of 175 recovery people, and found that the antibody value in the body was abnormally low, and 10 people even could not be detected.
The accuracy of testing is also a major issue. The British government earlier ordered millions of household antibody testing from Southeast Asian suppliers. However, Oxford University found that the results of the test were not accurate enough, prompting the government to withdraw the plan earlier last week.
Era Bndavid, a infectious diseaseist at Stanford University, believes that the early detection of this type of serotism may help more effectively measure community communication, rather than determine whether the subject is completely immune.For many infected people, there are only mild or even asymptomatic, so they have not received virus testing. The detection of antibodies can help comprehensively understand the degree of communication and calculate more accurate mortality.
