China News Service, Shanghai, March 13 (Reporter Chen Jing) At the press conference on the prevention and control of the new crown pneumonia epidemic in Shanghai held on the 13th, Lu Taohong, deputy director of the Shanghai Municipal Health Commission, said that there were 6 new cases of new crown pneumonia in Shanghai on the 13th. Local confirmed cases of pneumonia (mild) and 55 local asymptomatic infections; two new medium-risk areas.

  It is reported that among the 6 confirmed cases, 2 were returned by asymptomatic patients who had been admitted to the Shanghai Public Health Clinical Center, and 4 were found in centralized isolation and control; among the 55 asymptomatic infections, 4 44 cases were found in centralized isolation and control, and the rest were found by screening of relevant risk groups. All of them have been sent to the Shanghai Public Health Clinical Center for isolation treatment or isolation medical observation. The current situation is stable.

  According to reports, asymptomatic infections mainly refer to those who are positive for the nucleic acid test of the new coronavirus, but have no symptoms and signs such as sore throat, fever, fatigue, dry cough, and hyposmia, and there is no pneumonia on CT imaging.

For asymptomatic infections, Shanghai will conduct 14-day isolation medical observation, regular clinical diagnosis, nucleic acid testing, etc.

At the same time, asymptomatic infections are equivalent to the implementation of corresponding control measures and requirements for confirmed cases.

  Lu Taohong explained that due to the characteristics of the disease, the length of the disease course, individual differences, vaccination and other conditions, a small number of asymptomatic infected people may have abnormal symptoms and signs in the follow-up, and CT imaging shows abnormal conditions.

According to the national diagnosis and treatment plan and diagnostic standards, after the relevant asymptomatic infection is converted into a confirmed case, measures such as isolation and treatment will be implemented.

Such situations are more common at home and abroad.

He said that these two confirmed cases have also been implemented in the early stage of corresponding control measures.
