When he returned home at the beginning of the serious illness, the test of the virus nucleic acid was found again. The recovery of the Fuyang in various places, and the cunning new coronal virus brought new questions to the epidemic prevention and control.On February 27th, Zhong Nanshan, the leader of the National Health and Health Commission's high -level expert group and the academician of the Chinese Academy of Engineering, said at the Guangzhou outbreak conference that there were many reasons for the recovery patients in the hospital.Will it be transmitted to others?
Zhong Nanshan said that virus infection has its own laws. As long as there is sufficient antibodies for the new crown virus in the body, the patient will not be infected again, and the possibility of recurrence of patients is very low.But he also emphasized that while developing, he could not set an absolute conclusion.
At the Guangdong Provincial Epidemic Conference on February 25, Song Tie, deputy director of the Guangdong Provincial Center for Disease Control and Prevention, said that 14%of the discharged patients in the province had a phenomenon of Fuyang.Fuyang has no systemic conclusion. Experts have preliminarily judged that Fuyang is mainly because the patient's lung inflammation is still absorbed and has not yet reached clinical healing, so intermittent detoxification may be existed.
According to data from the Guangdong Provincial Health and Health Commission, as of 24:00 on February 26, the province had reported a total of 1,347 confirmed cases of new crown pneumonia, a total of 873 were discharged from hospital, and 7 cases were accumulated.
The latest new type of coronary virus pneumonia released by the National Health and Health Commission (the sixth edition of the trial) proposes that the suspected patients have two consecutive respiratory specimens of nucleic acid detection negative (at least 1 day interval), and the body temperature is returned to normal three days, respiratory symptoms of respiratory tract symptomsObvious improvement, lung imaging shows that acute exudation lesions are obviously absorbed, and they can be discharged and discharged.
There was no such virus before, and nucleic acid testing has only developed recently.Zhong Nanshan said that there are many reasons for the review of nucleic acid reviews. Detective reagents and detection methods may cause deviations, and the positive rate of specimens obtained from different sampling methods also varies.
An industry expert told Caixin reporter that the domestic throat swab was sampled from the respiratory tract sampling for disease detection.The United States is more sampled from the nasopharynx, which is more difficult, but the virus load may be higher, which can increase the detection sensitivity.
Earlier, the research team of the National Key Laboratory of Respiratory Diseases of Guangzhou Medical University was separated from the stool samples of new crown pneumonia patients, and the new crown virus was separated, suggesting that there may be new channels for epidemic dissemination, but the gastrointestinal infection pathway is clear.For the sake of insurance, some hospitals in Guangdong take the lead in sampling from the patient's feces to detect nucleic acid testing.
The 8th People's Hospital of Guangzhou (hereinafter referred to as the 8th Hospital of Guangzhou) is the main designated hospital for the treatment of patients in Guangdong Province.Li Yueping, director of the ICU of the hospital in the hospital, publicly disclosed on February 25 that the hospital found 13 patients with Fuyang during the discharge follow -up. These patients did not have the symptoms again.104 close contacts received nucleic acid detection, and the results were negative.
Cai Weiping, director of the infection department of the Eighth Hospital of Guangzhou, told Caixin reporter that the patients of Fuyang were mainly the anal -wiping nucleic acid detection to be positive.The test results are in gray areas with yin and yang, and are weakly positive.
Cai Weiping pointed out that it is not possible to determine whether the virus or virus fragments exist in the virgin virus.He believes that there are many substances in the stool sample, and there may be errors in the test.He suggested whether to have intensive research on whether Fuyang, discharged patients, to verify virus activity through epidemiological surveys and cell culture.
Zhong Nanshan also said that the residuals of the stool and intestinal tract may be observed in the discharged patients with patients discharged from the hospital.He suggested that the discharged patients are isolated at home. If the positive is reviewed, it can be checked again after 24 hours. If it is positive twice, he will go back to the hospital to observe.
On February 22, the Wuhan Xinguan Pneumonia Epidemic Prevention Headquarters issued a notice requesting the cure of new crown pneumonia to be hospitalized and unified to the designated place for 14 days of rehabilitation isolation and medical observation.
Sichuan and Hainan Province have also occurred in the case of individual discharged patients.The Hainan Health Commission suggested that all discharged patients were observed for 14 days, and throat and feces were performed during the expiration of the isolation period.When both tests are negative, the patient discharged patients can be discharged; when the discharge is full, the relevant personnel should also receive a review review again.
