(Fighting New Coronary Pneumonia) 155 asymptomatic infections have been converted to confirmed cases in this outbreak in Urumqi
China News Service, Urumqi, August 13 (Reporter Sun Tingwen and Zhao Yamin) Rui Baoling, director of the Urumqi Center for Disease Control and Prevention, said on the 13th that the proportion of asymptomatic infections in Urumqi was relatively high in the early stage. This is in line with the rapid, powerful and large-scale local control measures. The nucleic acid detection and investigation are related. Through large-scale nucleic acid screening, some patients with positive nucleic acid but not yet sick can be found earlier. The asymptomatic infections found early are not all true asymptomatic infections, and some of them are patients in the incubation period. As of August 12, 155 asymptomatic infections have been converted to confirmed cases.
On the same day, Xinjiang held a 27th press conference and answered questions from reporters on the current situation of the new crown pneumonia epidemic in Urumqi and its prevention and control work. At the press conference, Rui Baoling said that for asymptomatic infections detected in Urumqi, Urumqi strictly implements the "Regulations for the management of asymptomatic infections of the new crown pneumonia virus", reporting of asymptomatic infections, epidemiological investigations, and management of close contacts. The requirements and confirmed cases are basically the same. At present, once asymptomatic infections are found at all levels and types of medical and health institutions, they are required to complete direct online reporting within two hours and complete epidemiological investigations within 24 hours. For those with asymptomatic infections found, intensive medical observation shall be taken. After 14 days of intensive medical observation and two consecutive samples with negative nucleic acid test (the sampling time is not less than 24 hours), the medical observation can be cancelled.
She said that asymptomatic infections have no obvious clinical symptoms or mild symptoms during the incubation period, they often cannot seek medical treatment in time. Nucleic acid testing is the "gold standard" for diagnosing new coronary pneumonia, and it is also an important means to detect and identify asymptomatic infections.

"Because of the timely large-scale nucleic acid testing and investigation, some asymptomatic infections with positive nucleic acid but no disease were found early, and by insisting on early intervention and early treatment, rest and adequate nutrition, and Chinese medicine intervention were used to prevent them. Converted to a confirmed case. Once converted to a confirmed case, clinical symptoms appear and there are imaging changes on the chest radiograph, we will strictly follow the seventh edition of the diagnosis and treatment plan to actively treat, so that the treatment window will be extended. At present, early treatment is One of the keys to early recovery."
Rui Baoling also said that in response to the large number of asymptomatic infections, Urumqi has increased the screening of key populations and key areas, focusing on active screening of confirmed cases and close contacts of asymptomatic infections and the areas where they are located. At the same time, the monitoring role of the community and fever clinics will also be brought into play. According to the clues of the cases, the source of infection will be traced and managed. By increasing the sensitivity of monitoring, asymptomatic infections will be detected in time, and centralized isolation measures and epidemiological investigations will be taken in time.
Rui Baoling also added that carrying out multiple nucleic acid tests for key populations and key areas is conducive to the rapid identification and detection of asymptomatic infections, avoiding family transmission and the spread of the epidemic, and hopes that the general public will understand and actively cooperate.
