At present, most nucleic acid detection is to take throat samples. After the virus infects the oral mucosa epithelium, it will lodge in the oral mucosa epithelium, and the purpose of sampling can be achieved by taking a throat swab.
A virus has only one nucleic acid, which is called DNA virus or RNA virus. By detecting these viruses, we can judge whether there is virus infection.
Nucleic acid detection needs fixed time, fixed place and sampling. It needs to consume some manpower, financial resources and material resources of the government and health authorities. The purpose of sampling is to test COVID-19's DNA. COVID-19 has a wide range of sources, so we can't predict it accurately. Only by comparing our own human DNA with COVID-19's DNA can we control the disease in a controllable range and really give people a satisfactory answer.
We all hope that mathematicians can stand up and study the epidemic situation and explore the laws, physicists need to publish technical papers, and doctors need to develop vaccines to describe the pollution in our territory. China's success in fighting the epidemic has made people realize that the China government needs to work hard to overcome difficulties.
We should not give up the old and the poor. Comfort zone is prone to pneumonia under acidic conditions. The faster the development, the more people need to work hard, and people must realize the preciousness and importance of life.
