There are several influencing factors to cause disease, including the number of viruses, their virulence, and the biological environment in which they are located." Professor Wu Hongyi further explained that when a virus successfully enters the human body, the environmental conditions that affect its survival are our own immunity. If the patient's immunity is low when the virus invades, the number of viruses is large, or the infected virus strain is a more virulent one, it may cause relatively serious symptoms. Scientists and Viruses Marathon: Testing and Drug Development When an unknown epidemic breaks out, how do we know what kind of opponent we are facing? Let's use the hot Wuhan pneumonia as an example. At the end of 2019, there was an outbreak of "pneumonia of unknown cause" in Wuhan. At that time, some people wondered whether SARS Photo Manipulation Service had re-emerged, but there were different theories about the cause. And if you were a scientist, what would you do? If you want to find the murderer in a murder case, you will try to collect fingerprints, collect traces of microscopic objects, and compare various characteristics; and scientists actually do the same: after collecting viruses from patients, they try to cultivate them ; they can see its appearance through an electron microscope. Found to have the appearance characteristics of the coronavirus ; by analyzing the gene sequence in the virus , try to explain its origin and who the relatives may be. Once we know enough about our opponents, we can devise tests to find the virus lurking in patients. Professor Wu Hongyi explained that as far as virus testing is concerned, the most sensitive method is to detect nucleic acids, but the shortcoming of the experiment is that it takes about 6 hours. Another feasible method is to detect viral proteins (ie antigens) or antibodies produced by infected persons, such as enzyme immunoassay (ELISA). In addition to detecting patients through testing, another important goal is the development of therapeutic drugs.
