Recently, there have been cases of new crown and rejuvenation in many parts of the country, which has aroused everyone's attention. According to the statistics of Health Times, since January this year, at least 7 cases of fuyang after curing have been reported in at least 7 places across the country, and the number of cases is close to 40
On January 25, more than 30 cases of COVID-19 "Fuyang" patients were found in Shanghai
At the 94th press conference on epidemic prevention and control in Shanghai held on the afternoon of January 25. Wu Jinglei, director of the Shanghai Municipal Health Commission, said that at present, More than 30 cases of "Fuyang" have been found in Shanghai during the isolation period of 14 days after the cure.
On January 24, a covid-19 "Fuyang" patient was found in Beijing
On the evening of January 24, the Xicheng District of Beijing reported the nucleic acid testing of the new crown virus in the whole region. In nucleic acid testing of 1130680 people. Except for one person collected on 22 January who initially tested positive, the rest of the personnel tested negative.
On January 24, a new crown "Fuyang" patient was found in Shanxi
On the evening of January 24, Shanxi Fushan also notified a "Fuyang" patient who returned to Zhengzhou from the Philippines on December 16, 2020. On December 17, the nucleic acid test result was positive, and he was diagnosed as an asymptomatic infected person by the First Affiliated Hospital of Zhengzhou University and was hospitalized for isolation treatment. After the end of treatment, the nucleic acid test results were negative several times, but when the nucleic acid test of key people in the county was carried out in Fushan, Shanxi province on January 23, Wei Mou's nucleic acid test results were positive.
On January 20, a new crown "Fuyang" patient was found in Hebei
On January 20, Qinhuangdao, Hebei Province, reported a case of new crown Fuyang patient, who was positive for nucleic acid twice after entering Shanghai on December 18, 2020, discharged from hospital on December 30, and returned to Qinhuangdao City to return to Qinhuangdao City during the isolation period.
On January 15, a new crown "Fuyang" patient was found in Hebei
On January 15, Henan Lingbao notified a case of new crown Fuyang patient, who was positive for nucleic acid when he entered Chengdu on September 5, 2020, and returned to Fuyang after being discharged from the hospital, and was an asymptomatic infected person who was diagnosed and cured in Fuyang for overseas imports.
On January 6, a patient with the new crown "Fuyang" was found in Guangzhou
On January 6, a confirmed case imported from abroad in Haizhu District, Guangzhou, tested positive after discharge, and the second review result was negative.
On January 6, a new coronavirus "Fuyang" patient was found in Zhejiang
On January 6, Hangzhou, Zhejiang Province, reported a case of new crown Fuyang patient, who had been diagnosed with asymptomatic COVID-19 infection in the United Kingdom in April 2020, entered from Guangzhou in December, and arrived in Hangzhou after Fuyang.
According to the Global Times, for the successive occurrence of the "Fuyang" phenomenon, Li Taisheng, director of the Infectious Diseases Branch of the Chinese Medical Association and director of the Department of Infectious Diseases of Peking Union Medical College Hospital, once said that according to the existing research on the "Fuyang" problem of patients cured of new crown pneumonia, many so-called "Fuyang" are not necessarily the "endless" existence of the new crown virus in the patient's body, and the reasons for the positive nucleic acid test of the new crown cured patients are more diverse and need to be analyzed on a case-by-case basis.

There are three possibilities in patients with fuyang
Wang Guiqiang, director of the Department of Infectious Diseases of the First Hospital of Peking University, member of the medical treatment expert group of the joint prevention and control mechanism of the State Council, and member of the expert group on scientific and technological research, once explained that there are three possibilities for the emergence of Patients in Fuyang:
1, the new crown virus has a characteristic, that is, its virus duration is relatively long. So sometimes it may be after the recovery period from the lungs, and then it is discharged through sputum and so on. That is to say, such a patient, in fact, his virus did not really disappear, but said that the upper respiratory tract throat swab nasopharyngeal swab can not be found, but the lower respiratory tract in the lungs still have the virus.
2, for fuyang, it may be that the sensitivity of the detection is not strong enough. In the case of low detection sensitivity, upper respiratory tract specimens may not be detected at low viral loads.
3. Individual patients have persistent positive or compound positive due to relatively low immune function. Persistently positive cases, although not very numerous, deserve high attention.
Can Fuyang patients be infected?
Earlier, Zhong Nanshan, an academician of the Chinese Academy of Engineering and an expert in respiratory diseases, explained the problem of "Fuyang" patients in an interview.
Zhong Nanshan said that the so-called "fuyang", most of which should be fragments of nucleic acid rather than the virus itself, need to pay attention to two situations:
1. Whether the patient himself is relapsing, if the patient produces strong antibodies, he will generally not be infected again. As for whether the patients with Fuyang will be infected to others, specific analysis is needed, and in general, nucleic acid fragments are not contagious. Some scholars have cultured throat swabs and secretions in "Fuyang" patients, and no virus has been cultured.
2, the patient originally has a lot of underlying diseases, but the symptoms have improved, and has not fully recovered, these patients can not rule out that there is contagiousness.
Zhang Wenhong, director of the Department of Infectious Diseases at Huashan Hospital affiliated to Fudan University, has also publicly stated that there is a complex scientific mechanism behind Fuyang, but Fuyang does not have significant clinical significance, and it will not cause a large-scale outbreak in the history of epidemiology, and there has not been a case of human-to-human transmission so far, because the virus is "dead".
