Daily Economic News Release: How to fight the epidemic prevention and control initiative?West China Expert: The next 3~5 days is the key
À 9 o’clock in the evening on December 8, the Chengdu Municipal Government held a press conference on epidemic prevention and control work to inform the prevention and control of the new crown pneumonia epidemic in Chengdu. Selon les rapports, le 8, Chengdu added 4 new confirmed cases of new coronary pneumonia and 1 asymptomatic infection.
After Wuhan, sporadic epidemics continued to occur in many places. How to take the initiative to prevent and control the epidemic in winter? How do individuals protect themselves? In this regard, a reporter from “Daily Business News” (hereinafter referred to as NBD) interviewed Li Jiayuan, a professor and doctoral tutor in the Department of Epidemiology and Health Statistics, West China School of Public Health, Sichuan University, and Jin Dongyan, a professor and virology expert at the University of Hong Kong.
Li Jiayuan: Isolating close contacts is valuable experience
NBD: In your opinion, what needs to be strengthened in order to trace the source of infection as soon as possible?
Li Jiayuan: The most important means of tracing the source of infection is epidemiological investigation, asking about possible contact with foreign personnel and personnel from epidemic areas or contact with cold chain materials within 2 weeks before the onset of the case, and combining information with big data when necessary Trajectory analysis may find the source of infection. En outre, hospitals at all levels and types of hospitals will definitely strengthen symptom monitoring and nucleic acid testing of medical personnel. The next 3 pour 5 days are critical, so please actively cooperate with residents and friends who are designated as the screening area and go to the designated place to participate in the nucleic acid screening as soon as possible to fight the virus.
NBD: What conditions do you think are close contact with new coronary pneumonia?
Li Jiayuan: The seventh edition of the National Prevention and Control Plan defines the definition of close contacts. Simply put, it is a person who is in the same room with the infected person from 2 days before the onset of symptoms and is in the same room with the infected person, who is in a scene with daily contact, droplet transmission risk, or aerosol transmission risk, and is not effectively protected. The 14-day medical quarantine of these people is a valuable experience for the success of the first stage of my country’s epidemic prevention and control.
NBD: In the context of the discovery of local cases of new coronary pneumonia in Chengdu, what do you think is the most important thing for citizens to take good personal protection?
Li Jiayuan: The emergence of local cases in Chengdu indicates that there may have been undetected infections (source of infection) in the early stage. The extent of transmission needs to be determined through 3 pour 5 days of observation.
Jin Dongyan: The most important thing is to prevent super spread
Regarding the epidemic prevention and control strategies in the autumn and winter season, Jin Dongyan said in an interview with reporters that personal hygiene, wearing masks, reducing gatherings and maintaining social distance should be paid attention to. The most important thing is to prevent super spread.
“Super transmission is a small probability event, but it often happens inadvertently.” Jin Dongyan emphasized that what we can do is to avoid this situation as much as possible, detect super transmission as soon as possible, and minimize its scale.
