(Health Times reporter Zhang Meng) In recent days, local epidemics have occurred in Shenyang, Liaoning and Beijing. Shenyang announced on the 23rd that it has entered a wartime state. Both places are positive cases after incoming personnel are released from centralized isolation. Many people have discussed whether it is necessary to extend the centralized quarantine period. For example, some netizens proposed to extend the centralized quarantine by 14+7? In this regard, experts said that as long as the existing policies are strictly implemented in accordance with regulations, there is actually no need to extend the centralized quarantine period.
Both Beijing and Shenyang, Liaoning have positive cases after being released from quarantine
On December 23, the Shenyang Municipal Health Commission announced that a case of a Korean returnee who returned to Shenyang tested positive for nucleic acid after being released from quarantine.
notice shows that the patient entered the country from Shenyang from South Korea. During the 14-day centralized medical observation, the nucleic acid and serum antibodies were both negative. Quarantine will be lifted on December 13. At 20:00 on December 22, the patient went to the fever clinic of the First Affiliated Hospital of China Medical University for treatment. At 2:40 on December 23, the hospital diagnosed him as a suspected case. The Shenyang Municipal Center for Disease Control and Prevention collected his biological specimens for nucleic acid testing, and the result was positive.
Since the epidemic has become normalized, cases of confirmed cases of new coronary pneumonia after being released from quarantine have occurred frequently.
On November 28, a 27-year-old man from Jilin arrived at Beijing Capital Airport on HX336 flight from Hong Kong. After health screening and a pharyngeal swab was collected for nucleic acid test, the result was negative, and the nucleic acid test results were all negative during centralized isolation. After the centralized quarantine ended on December 12, in order to conduct 7 days of self-health observation, he stayed at the Chaoyang District Hanting Hotel (Dashanzi Branch). He developed symptoms of fever and diarrhea on December 13. On December 14, he went to the fever clinic for treatment. The nucleic acid test result of the new coronavirus was positive.

. Does the centralized quarantine time need to be extended?
Health Times . A reporter found that the current epidemic situation in various places is mainly related to imported cases from abroad, and incoming personnel are required to be centralized quarantine for 14 days. However, all the above cases are the end of the quarantine period, that is, the diagnosis is confirmed after 14 days. Does this mean that the period of centralized quarantine needs to be extended?
"Based on the existing evidence, the incubation period of most patients is 2-14 days, which is also the reason for setting up quarantine for 2 weeks. However, there are indeed a very small number of cases where nucleic acid positive and symptoms appear later than 2 weeks, and similar situations have occurred at the past at home and abroad." Zhang Yu, an associate researcher at the Chinese Center for Disease Control and Prevention, told the Health Times reporter, but this does not mean that the current 14-day quarantine cycle is inappropriate, because most patients are still in this cycle, and the length of the quarantine time still needs to be considered.
In fact, the confirmed case returns to positive after the quarantine, or the confirmed case of new coronary pneumonia after a few days of nucleic acid negative isolation is not unique to imported cases from abroad. Wu Zunyou, chief epidemiologist of the Chinese Center for Disease Control and Prevention, explained at a press conference of the State Council’s Joint Prevention and Control Mechanism on December 21 that since the outbreak of the epidemic, some special cases have been reported in various places. There are two reasons for these phenomena. On the one hand, it may be natural phenomena after the infection of the new coronavirus. That is to say, the clinical manifestations of each person after the infection of the new coronavirus are different. Some are mild and some are severe, and some are even so serious that the entire lung is lesions, that is, there are many viruses in the lungs, but they cannot be collected when taking pharyngeal swabs or nasopharyngeal swabs, which sometimes yin and sometimes yang phenomena occur. On the other hand, it also depends on the quality of the sampling. If the sampling site is correct and the sampling operation is standardized, the possibility of a positive specimen will be high.
Zhang Yu also emphasized to the Health Times reporter that considering the above situations may occur, and in order to reduce the occurrence of such situations, many cities in China, such as Beijing, strictly adopt the 14+7 method, that is, after 14 days of centralized isolation, they need to conduct another 7 days of self-health monitoring at home quarantine. The 7-day home self-health monitoring after the 14-day centralized isolation is also adopted closed-loop management. Therefore, as long as the regulations are strictly implemented, there is actually no need to extend the centralized isolation period.
Wu Zunyou suggested that incoming personnel should take protection and take personal protective measures during the entire journey, including after entering the closed-loop management process. Because there is a high possibility of infected people among the incoming population, you must insist on wearing masks, pay attention to hand hygiene, and maintain a certain social distance throughout the process, and do not communicate and talk with strangers. Doing these will help reduce the risk of infection during the journey. After being released from isolation, you should also pay attention to your physical condition. If you are unwell, you must seek medical treatment in time. /////
