The "Patient Zero" of COVID-19 is very important. How much help will it bring to the epidemic?

As time goes by, the number of new coronavirus infections has gradually declined in our country. Through the concerted efforts of the people across the country to fight the epidemic, the number of new cases in several provinces in my country has been in single digits for several consecutive days. Therefore, in order to create a vaccine to treat the epidemic earlier, medical staff urgently need to find patient zero of the new coronavirus. The so-called patient zero does not refer to the carrier of the virus, but the first person to be infected. When a large-scale epidemic spreads, only by quickly finding patient zero can we know when the virus spread. , when the patient was infected and a vaccine to treat the virus could be discovered earlier. Therefore, finding this patient zero is the top priority for the further progress of the epidemic. The reason why Patient Zero is the top priority is because in Patient Zero, we can find the source of infection, symptoms of infection, etc., so that we are no longer confused in the fight against the epidemic and can prescribe the right medicine. At the same time, finding Patient Zero can also reveal some potential dangers, such as whether there will be new sources of infection for this type of virus. Once Patient Zero is identified, medical staff will be able to learn about his daily life from Patient Zero, which can play a vital role in subsequent investigation work and finding the source of the new coronavirus. ? Although our country has determined that the South China Seafood Market in Wuhan is an important outbreak area shortly after the outbreak of the new coronavirus, it cannot be determined that the South China Seafood Market was the first place where the epidemic broke out. According to expert analysis, the South China Seafood Market Therefore, it is an important outbreak area because the viscera and blood of wild animals sold in this market all year round can be seen everywhere. Such conditions have created extremely favorable living conditions for the new coronavirus infection, and whether the existence of Patient Zero is related to the Huanan Seafood in Wuhan The market is closely linked, and our country's medical staff are now investigating.
