(Fighting New Coronary Pneumonia) Strict Prevention, Control and Management of Asymptomatic Infections in China
China News Agency, Beijing, April 1st. On April 1st, China notified the asymptomatic infection of new coronary pneumonia for the first time, and asymptomatic infections were strictly controlled in various places.
The Fujian Provincial Health and Health Committee stated that from 00:00 to 24:00 on March 31, one new case of asymptomatic infection was imported from Fujian province, which was imported by the Philippines and reported by Quanzhou City; as of 21:00 on March 31, Fujian Province It is reported that there are 16 cases of asymptomatic infections imported from outside the province and abroad who are still receiving centralized medical observation, including 2 cases from outside the province and 14 cases from outside the country.
The Guangdong Provincial Health and Health Committee notified on April 1 that as of 24:00 on March 31, 50 cases of asymptomatic infection were still under medical observation, of which 38 cases were imported overseas. On the 31st, one new case of asymptomatic infection was reported, which was imported from Hubei, Shenzhen.
Hainan Provincial New Crown Pneumonia Epidemic Prevention and Control Work Headquarters held a briefing on the 1st. As of 10:00 on April 1, Hainan Province reported 4 cases of asymptomatic infection of New Coronary Pneumonia under medical observation, all of which were imported from overseas.
Zheng Jin, a spokesman for the Shanghai Municipal Health Committee, disclosed on the 1st that there is no asymptomatic infection of new crown pneumonia in Shanghai under medical observation.
Asymptomatic infection of neocoronavirus refers to those who have no relevant clinical symptoms, such as fever, cough, and sore throat, which are self-perceivable or clinically identifiable symptoms and signs, but positive for the pathogenic detection of neocoronavirus in respiratory specimens. At the present stage of research, it is believed that asymptomatic infection is contagious, but the length of infectious period, the degree of infectivity, and the mode of transmission need to be further studied.
Zhang Zhoubin, deputy director of the Guangzhou Centers for Disease Control and Prevention, introduced that for asymptomatic infections, the National Health Committee of China in the third edition of the "Pneumonia Prevention and Control Program for New Crown Virus Infection" released on January 28 explicitly Included in prevention and control management. There are requirements for reporting deadlines, case epidemiological investigations, and identification and management of close contacts.
For the prevention and control of asymptomatic infections, Fujian officials propose to further expand the detection scope to new patients with new coronary pneumonia and close contacts of those who have found asymptomatic infections, key areas and populations with special requirements, etc. For those who test positive, conduct an epidemiological investigation in accordance with the requirements within 2 hours, complete the investigation within 24 hours, and follow up the first time to conduct centralized medical observation of close contacts in accordance with laws and regulations.
Zheng Jin pointed out that Shanghai will strengthen screening and follow up with close contacts of asymptomatic infected persons; strengthen 100% nucleic acid testing of all immigrants coming to Shanghai and sampling screening of high-risk persons; strengthen key populations and places Monitoring.
Liao Zhiwu, director of the Hainan Provincial Center for Disease Control and Prevention, said that asymptomatic patients should, in principle, strictly follow the management and control requirements of confirmed cases, and firstly concentrate in a designated hospital for 14 days and negative for two consecutive nucleic acid tests (sampling time at least 24 hours), or if Positive tests at the expiry date must continue to be quarantined at the designated hospital until two consecutive negative tests (sampling time interval of at least 24 hours), and then transferred to the centralized isolation hotel to continue observation for 14 days. At the end of the period, a nucleic acid test can be performed. If negative, the quarantine can be lifted. If clinical manifestations occur during isolation medical observation, they should be promptly referred to confirmed cases for standardized treatment. (Finish)
