First, clear three questions:
For local cases, three issues need to be clarified. ? Zhong Nanshan said that the first question is who is the source. It is necessary to find out the source and find out that the imported cases are locally produced; The second question is who has contacted it and needs to be tracked; The third question is how big the scope is, and extensive screening should be carried out in relevant areas. ? Only in this way can the disease be controlled in the shortest time. ? Zhong Nanshan analyzed that the epidemic was related to the market of fresh box horses. It is spread by people, and the spread of contaminated food is still unclear. ? Judging from the case of Beijing Xinfadi Farmers' Market, it may be closely related to contaminated food, and this problem needs vigilance. This question. ?
Two. Follow up the contact closely:
He said that Guangdong responded quickly to the epidemic and conducted relevant investigations. Five asymptomatic infected people who were in close contact with the confirmed patients were found. A large-scale investigation was carried out in the area involved, and the relevant locations were quickly killed. ? COVID-19's incubation period is generally 3? Seven days, with an average of more than four days. During this period, early detection and isolation are important and effective methods. ? Zhong Nanshan said that at present, more than 654.38+10,000 samples have been screened out in Guangdong Province, and no other positive samples have been found except five asymptomatic infected people, which provides a preliminary guarantee for epidemic control. Sometimes an inspection may not explain the problem, but it is also necessary to closely follow the contacts and clean up the relevant areas. ? I don't think the epidemic will spread on a large scale. ?
Three. Risk of food contact infection:
Novel coronavirus has been warned of the epidemic. He said that from March to August, the national epidemic situation was basically controlled. In the past five months, patients have been found in many parts of the country. The key to deal with the epidemic is the full cooperation of the local government and everyone. ? At present, everyone is basically immune, and they will be infected as soon as they are infected. What we need is strict prevention and control. This will be safer if it can be done well. ? For the general public, Zhong Nanshan suggested, first of all, to avoid areas with high epidemic incidence. Second, imported food should be washed and cooked before eating. ? This may be, but not the most important, the risk of food contact infection. Now the main thing is to eliminate panic. ?
Zhong Nanshan said that in response to the epidemic, the government and local medical and health institutions responded quickly, and the people were vigilant, cooperated with prevention and control, and especially actively participated in the investigation. ? On this basis, I don't think the epidemic will spread widely. ?
