The new coronavirus pneumonia is supposed to have been first initiated from Wuhan, and now its spread is still relatively wide because it has spread to almost all parts of the country, including at home and abroad, so the exact source is not clear. Its associated hazards should be mainly peripheral infections. The number of cases in Wuhan accounts for about 80% of the cases, so the virus should be transmitted from Wuhan, but the specific related infections are still in the process of further observation and research to collect cases, so there will be a definitive conclusion in the future. There is no need to overly panic at the moment, instead we should pay attention to whether there are related infected patients or patients with related symptoms around, timely prevention is still very meaningful.
