Almost the whole world is fighting against COVID-19, and every country is trying its best to find effective ways to fight the virus. Donating plasma with antibodies is also a feasible way. With antibodies, you can resist some virus attacks, relieve physical pain and recover faster. The infection rate in COVID-19 is very fast, and there is a certain mortality rate. Besides, there is an incubation period in COVID-19. If the number of confirmed cases in a place suddenly exceeds 100, it is very likely that the number of confirmed cases will increase sharply after one week, because COVID-19 spreads through respiratory tract and even contact, which greatly increases the probability of cross-infection. If one person in the supermarket is a potential infected person, everyone in the supermarket will be infected.
Potential infected people are the scariest. He doesn't know that he is infected, so he will unconsciously spread the virus to people around him. It's too late to find out, but we don't have to be afraid. We can detect whether we are asymptomatic infection through nucleic acid testing, and then isolate it in time to avoid spreading the virus to people around us.
Since the epidemic is not over yet, we should try to stay at home. If you want to go out, you must wear a mask and wash your hands with household disinfectant to ensure absolute safety.
