Two. Prevention and control measures taken in Wuxi After the asymptomatic cases of new coronary pneumonia imported from abroad appeared in Wuxi Economic Development Zone, the emergency plan for prevention and control was quickly launched. Public security and other departments conducted an epidemiological investigation on Wang Jin. 65,438+0,367 people have been identified, including 63 close contacts, 65,438+065,438+07 close contacts and 65,438+065,438+087 others. Close contacts and close contacts have all concentrated and isolated medical observation. After collecting samples for testing, fortunately, all the results were negative. The prevention and control personnel also carried out a comprehensive disinfection of Wang's activity area, including the hotel elevator, living room, hotel corridor hall, hospital emergency room, CT room, noodle restaurant, underground garage of the community, etc., with a disinfection area of 4,530 square meters.
Third, why are there asymptomatic infections? Epidemic prevention personnel said that asymptomatic infection appeared too many times in China, which is not a unique phenomenon of imported cases abroad. The positive result appeared in the isolation period 14 days. On the one hand, the clinical manifestations of each person infected with COVID-19 are different, and there are individual differences, and some of them are even serious enough to have lesions in the whole lung, but they are not collected in swab collection. On the one hand, the original sampling may be incorrect and irregular.
Fourth, the current prevention and control tips: 1, friends returning from abroad should also pay attention to preventive measures. Because it is easier to mix in infected people among people entering the country. Always wear a mask, pay attention to the hygiene of exposed parts of the body, keep a certain social distance, and try not to talk to strangers.
Don't go out for the next two weeks. Do a good job of home isolation, self-health observation and regular nucleic acid detection according to relevant requirements. Report the abnormal situation to the local prevention and control department in time, and don't hide the truth.
3. Family members living with immigrants should also reduce going out, and when they have to go out, they should take preventive measures. Judging from the current situation in Wuxi, Wang's self-prevention measures in Wuxi are still good, and no one else is infected.
? Conclusion: The epidemic situation abroad continues to spread, and local confirmed cases or asymptomatic infected people appear in many places in China. The epidemic situation is still severe and complicated. We should reduce unnecessary gatherings and trips, and advise the elderly and people with basic diseases to avoid going out during holidays. During the trip, you should obey the relevant requirements of the prevention and control work in COVID-19, the destination of the trip, and prepare masks, hand-free disinfectant, disinfectant wipes and other items. Wear a mask when touching others, keep your distance and wash your hands frequently. Self-health monitoring should be carried out after returning from travel. These measures can not only reduce the risk of COVID-19 transmission, but also prevent influenza and other common respiratory infectious diseases in winter and spring.
