Li Jiayuan: Isolare i contatti stretti è un’esperienza preziosa
NBD: Secondo te, cosa che va rafforzata per poter risalire al più presto alla fonte del contagio?
Li Jiayuan: Lo strumento più importante per risalire alla fonte dell’infezione è l’indagine epidemiologica, chiedere informazioni su possibili contatti con personale straniero e personale proveniente da aree epidemiche o contatto con materiali della catena del freddo all'interno 2 settimane prima dell'inizio del caso, e combinare le informazioni con i big data quando necessario L’analisi della traiettoria può trovare la fonte dell’infezione. Inoltre, hospitals at all levels and types of hospitals will definitely strengthen symptom monitoring and nucleic acid testing of medical personnel. The next 3 A 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.

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.
