Science magazine published an interview with the head of the Chinese Center for Disease Control and Prevention, George Gao. GAO oversees 2,000 staff at the Chinese Centers for Disease Control and is still engaged in scientific work. In January, he was part of a team that performed the first isolation and ascertainment of Acute Respiratory Syndrome 2 (SARS-CoV-2), a virus that causes COVID-19. One of the questions he answered is what other countries can learn from the way China has fought coronavirus. “Physical distance is a basic strategy for controlling any infectious disease, especially if it is a respiratory infection.
First, we used non-pharmaceutical strategies because you do not have any specific inhibitors or medications and do not have vaccines. Second, you need to be sure to isolate each case. close contacts should be quarantined: we spend a lot of time trying to find all those close contacts and make sure they are quarantined and isolated. Fourth, suspend public gatherings.
Fifth, restrict movement, ”advised Gao. He said what, in his view, is wrong with other countries. “In my opinion, the big mistake of the US and Europe is that people don’t wear masks. This virus is transmitted by droplets and close contact. Drops play a very important role – you have to wear a mask because when you talk, the drops always come out of your mouth. Many people have asymptomatic or pre-symptomatic infections.
If they wear face masks, it can prevent the virus-carrying droplets from escaping and infecting others, “he said. He added that thermometers are everywhere in China and that people should try to measure the temperature as much as possible so that those with a high temperature are not out. “The infected should be isolated. This has to be done everywhere. You can only control COVID-19 if you can remove the source of the infection. That’s why we built modular hospitals and turned the stadiums into hospitals, ”Gao explained.
He said they have not yet been able to find out what caused the infection in China and that they are still working on it. He said there were two possibilities – that the virus originated from the market in Wuhan, or that it was a country from which it had spread enormously. China says it still lacks collective immunity, but that the virus is no longer transmitted locally. He also added that Chinese scientists are trying to discover the vaccine and medicines for COVID-19.
