The transmission of asymptomatic infection is weak
With the further development of the disease, asymptomatic infections have appeared in many areas, which may be the most worrying place. At present, asymptomatic infections are more common among family members. They have no obvious clinical manifestations, so patients with the virus may cause transmission.
However, it is gratifying that Li Xingwang, an expert member of the national medical team, said that asymptomatic patients are relatively light, and the amount of virus is related to the severity of the disease, so their transmission ability will be weaker.
The fifth edition of diagnosis and treatment plan
In addition, the diagnostic standard of suspected cases in Hubei Province has removed the imaging characteristics of pneumonia. Interpretation by Li Xingwang: This is to increase the diagnosis ability of primary medical institutions, because primary medical institutions do not have CT equipment, so in many cases, as long as the patient has fever and respiratory symptoms, combined with the epidemiological history, it will be diagnosed as a suspected case, in order to better control the source of infection.
