(Fighting against new crown pneumonia) Zhong Nanshan: Guangdong Lufeng epidemic will not spread widely
China News Service, Guangzhou, August 16 (Cai Minjie) Zhong Nanshan, an academician of the Chinese Academy of Engineering, said in an interview with the media on the 16th that Guangdong has responded quickly to the new crown pneumonia epidemic and has currently carried out large-scale screening in areas related to the epidemic. Zhong Nanshan judged that, in general, the Lufeng epidemic will not spread on a large scale, and there is no need to panic.
Zhong Nanshan analyzed that the epidemic is related to the Hema fresh market, but whether it was spread from person to person or from contact with contaminated food, it is still unclear. "From the case of Beijing Xinfadi Farmer’s Market, it seems that it may be Contaminated food is closely related, and this issue requires vigilance."
"For local cases, there are three issues to be clarified." Zhong Nanshan said, the first question is where did the source come from, and whether it was an imported case or a local one; the second question is who has been in contact with it, right This needs to be tracked; the third question is how large is the scope and extensive screening should be carried out in relevant areas. "Only by accomplishing these rules, will it be possible to control the condition in the shortest time."
Zhong Nanshan said that the response to the epidemic in Guangdong was relatively fast, and related screening was carried out soon. Five asymptomatic infections who were in close contact with the confirmed patient were found, and large-scale screening and rapid elimination were carried out in the involved areas and related places. .
"The incubation period of new coronary pneumonia is generally 3 to 7 days. Early detection and early isolation during this period are the most important and effective methods." Zhong Nanshan said that Guangdong currently screens hundreds of thousands of samples, except Apart from the five asymptomatic infections found, no other positive samples have been found, which provides a preliminary guarantee for epidemic control. But sometimes an inspection may not explain the problem, so it is necessary to closely trace contacts and clean up the involved areas.
"This epidemic also shows that the epidemic has basically never stopped." Zhong Nanshan said that after the national epidemic was basically controlled in March, it has now reached August. In the past 5 months, patients have been found in many places across the country. The key to dealing with the epidemic is the joint efforts of the local government and everyone.
"At present, everyone has basically no immunity and needs to be strictly prevented and controlled. If this can be done well, it is relatively safe, and there is no need to panic." For ordinary people, Zhong Nanshan suggested that first of all, go to areas with higher risks of epidemics. Secondly, for imported food, wash it before eating and cook it well. “This possibility may be transmitted to people due to contact with food, but it is not the most important.”
Zhong Nanshan said that due to the epidemic, the government and local medical and health institutions responded quickly, and the people were also very vigilant, especially actively participating in the screening. "On this basis, I don't believe the epidemic will spread widely." (Finish)
