 Wuhan time: 20 days from the arrival of the expert group to the mystery of Fengcheng


On February 6, there were 1501 new cases of coronavirus pneumonia in Wuhan. According to experts, this is only a new case confirmed by nucleic acid test, which is not a complete increase in the number of cases if considering patients who have not yet had the opportunity to receive nucleic acid test.

Wuhan and even Hubei are the key battle of the national anti epidemic war. Wuhan announced closure on January 23, 16 days after February 7. The epidemic situation in Wuhan is still at a critical juncture.

On December 31, 2019, Wuhan government disclosed for the first time the outbreak of pneumonia of unknown cause. On January 20, 2020, Zhong Nanshan publicly announced that human to human transmission of new coronavirus pneumonia was the key 20 days for Wuhan. Looking back at the whole information chain, we cant help but ask: have we ever had a chance to retrieve all this at a critical point in determining the fate of Wuhan and the direction of the whole epidemic?

December 31 to January 10: is it SARS?

The original information was circulated in the medical system.

At 5:00 p.m. on December 30, Li Wenliang, an ophthalmologist of Wuhan Central Hospital, sent a message in the wechat group: 7 SARS cases were confirmed in the South China market! An hour later, he added, the latest news was that coronavirus infection has been confirmed and virus typing is in progress..

At 8:00 that night, Xie Linka, a oncologist at Wuhan Union Medical College Hospital, also gave a warning in the wechat group of her cancer center: the younger martial sisters of the infectious diseases hospital sent messages in the same group, and they should not go to the South China seafood market in the near future, where many people are suffering from unexplained pneumonia (similar to SARS). Today, our hospital has received many cases of pneumonia patients in the South China seafood market. Please wear masks and ventilate

The news was quickly screenshot and spread quickly through wechat, Douban and other social media.

At 2:00 p.m. on December 31, Wuhan Municipal Health and Health Commission publicly reported the epidemic situation of unexplained pneumonia: multiple cases of pneumonia received were related to South China Seafood City. After receiving the report, the municipal health and Health Commission investigated and found 27 cases of unexplained pneumonia and 7 cases of severe pneumonia, but 2 cases were expected to go out of the hospital in the near future, no human to human phenomenon was found, no infection of medical staff was found; detection of pathogens and An investigation into the cause of infection is underway. The disease is preventable and controllable. .

Wuhan municipal government executive meeting held on this day did not mention the epidemic. It can be confirmed that on December 30, Wuhan health and Health Commission issued an internal document requiring medical institutions within the jurisdiction to immediately check and count the patients with similar characteristics who had received treatment in the past week. According to CCTV, the working group and expert group of the National Health Commission have arrived in Wuhan.

According to a later report in Changjiang Daily, Zhang Jixian, director of respiratory and Critical Medicine Department of Hubei integrated hospital of traditional Chinese and Western medicine, was the first to report the outbreak. On December 29, after receiving a number of cases from the South China seafood market, the hospital reported them directly to the disease control office of the provincial and municipal health care Commission.

On January 1, 2020, Wuhan closed the South China seafood market after the public attention. The national health and Health Commission has set up a leading group for epidemic response and disposal headed by Ma Xiaowei, the director of the group, to discuss and analyze the development and changes of the epidemic, to study and deploy prevention and control strategies and measures, and to guide and support Hubei Province and Wuhan city to carry out case treatment, epidemic prevention and control and emergency disposal in a timely manner.

Everything is in order. However, the most interesting news of the day came from Wuhan police. Police micro blog account safe Wuhan announcement: eight people were summoned and dealt with for spreading rumors. It was later learned that some of them were medical workers.

At that time, I knew it was a real event, but I didnt know how much follow-up would be and what it would look like, sherinka told the economic observer on February 1. We dont have first-hand data, just early warning.

Another doctor with public identity is Li Wenliang, who was diagnosed with new pneumonia on February 1 and died in the early hours of February 7.

On January 3 and 5, Wuhan health and Health Commission continued to report the epidemic information, and the number of patients diagnosed with viral pneumonia of unknown cause increased to 59 on January 5, epidemiological investigation shows that some cases are business households of South China Seafood City in Wuhan. No obvious evidence of human to human transmission and no infection of medical staff was found, the report said. The report on December 5 also showed that the earliest onset time of the case was December 12, 2019, and the latest onset time was December 29.

This is the earliest case occurrence time traced back in Wuhan notification. The report said that prevention and control work is proceeding in an orderly manner, including treatment of patients, isolation of treatment cases, case search and retrospective investigation, close contact tracking, off-season disposal and hygiene investigation of South China seafood market, epidemiological investigation and etiology tracing, etc.

Pathogen identification and etiology tracing are also in progress, and respiratory pathogens such as influenza, avian influenza, adenovirus, SARS and mers are excluded successively.

According to the official disclosure afterwards, on January 3, China informed the United States and the World Health Organization (who) of the epidemic information for the first time.

On January 5, the clinical center of public health affiliated to Fudan University detected the whole genome of Wuhan unidentified pneumonia, and found that the homology between Wuhan unidentified pneumonia and SARS coronavirus was as high as 89.11%. It was speculated that it should be transmitted through respiratory tract, and suggested to the national health and Health Commission: take corresponding prevention and control measures in public places.

On January 6, the CDC launched a secondary response to public health emergencies within the epidemic situation in Wuhan - the CDC can judge and recommend several levels of response to the epidemic situation. According to the national emergency plan for public health emergencies, in case of major public health events, the provincial peoples Government shall decide to start the secondary response.

On this day, Wuhan entered the two sessions time.

According to caixin.com on February 1, on January 6, a respiratory physician in Hubei integrated hospital of traditional Chinese and Western Medicine (Xinhua Hospital) had a lung abnormality. The lung CT showed a small shadow, showing ground glass shape, but he had not been to the South China seafood market. The hospital held an internal meeting, stressing that the situation should not be leaked, especially not tell the media. The hospital was then infected by a number of medical staff. Liang Wudong, head of the otolaryngology department of the hospital, who died on January 25, was also the first medical staff to die of the new coronavirus pneumonia in Wuhan.

On January 7, according to the test conducted by the laboratory of China Center for Disease Control and prevention, the expert group preliminarily determined that the pathogen of this case of viral pneumonia of unknown cause in Wuhan was a new type of coronavirus - the seventh coronavirus known to human beings. Two days later, Xinhua announced that China had tested the genome of Wuhans unexplained pneumonia as a new type of coronavirus.

On January 10, the Chinese Center for Disease Control and prevention announced the viral gene sequence and diagnostic reagents for pneumonia of unknown causes in Wuhan. The next day, the National Health Commission announced that China would share the gene sequence information of the new coronavirus with the World Health Organization.

On January 10, the two sessions of Wuhan ended. Wang Guangfa, a member of the expert group of the National Health Commission and director of the respiratory and Critical Medicine Department of the first Peking University Hospital, said in an exclusive interview with Xinhua that the epidemic situation is under control. Chinese Spring Festival begins - everything seems calm.

One exception is that the Hong Kong SAR of China has been on the alert.

On the night of Wuhans report of the epidemic on December 31, 2019, the Hong Kong food and Health Bureau held an expert meeting to evaluate the prevention and control measures; on January 3, the chief executive visited the West Kowloon high speed railway station to inspect the prevention and control measures at the entry and exit ports; on January 4, the Hong Kong side reported 7 suspected cases, announced the contingency plan and initiated the serious contingency level; on January 8, the SAR government included the Wuhan unexplained pneumonia into the statutory Supervision of infectious diseases . Is Hong Kong making a fuss? This is the question of many people.

11-18: Zero new and no notification

On January 11, Wuhan Municipal Health Committee announced that according to the newly revised pathogenic nucleic acid detection method, 41 cases of pneumonia with new coronavirus infection were preliminarily diagnosed in Wuhan.

There were 59 cases of viral pneumonia with unknown cause reported in Wuhan on the 5th, 6 days after the last report. After the pathogen of unexplained viral pneumonia was initially determined as a new type of coronavirus, the national, provincial and municipal expert groups revised the diagnosis, treatment, monitoring and other programs of unexplained viral pneumonia, the report said.

According to Yu Changping, a critical disease expert and deputy chief physician in respiratory department of peoples Hospital of Wuhan University, the Economic Observer reported that the diagnosis of early new crown pneumonia is very difficult - it needs the signature of experts and leaders to check the coronavirus.

But caixin.coms interview with Peng Zhiyong, director of the Department of critical medicine of Central South Hospital of Wuhan University, confirmed that before, the expert group of the National Health Committee had made a set of diagnostic criteria after investigating in Wuhan Jinyintan hospital: to have a history of contact with the seafood market in South China, to have fever symptoms, to have a positive virus test, and to be able to be diagnosed only when all three criteria have been met. But the first-line doctors said that the diagnostic standard was too harsh - according to this standard, it is difficult for anyone to be diagnosed, especially the third point, which is very harsh. In fact, very few people can do virus testing; it is easy to miss the real patients. This is an infectious disease. The standard of diagnosis is too tight. It is harmful to society to let go of the sick people. .

Until the second expert group appointed by the national health care came to Wuhan on January 18, the number of confirmed patients increased dramatically.

The January 11 circular also mentioned that one case of death occurred in the confirmed patient on January 9. This is the first time that there has been a death in the official report. No clear evidence of human to human transmission has been found; up to now, no relevant cases have been found in all close contacts, including medical staff - since January 3, 2020, clinical and epidemiological investigations show that no new infections have been found in patients..

A study published January 26 in the New England Journal of Medicine showed seven cases of infection among medical staff between January 1 and 12 - a retrospective study, the authors said, but did not show when they learned the facts.

On January 11, the two sessions of Hubei Province opened. From the 12th to the 16th, Wuhan Municipal Health and Health Commission began to report the situation of the previous day on the next day. The number of new cases in these five days is zero.

In the empty window period of the epidemic, all kinds of information are still flowing.

On January 12, Thailand announced the first confirmed case outside China, and began to measure the temperature of tourists at the airport; on January 13-14, Wuhan received a field visit from a Hong Kong, Macao and Taiwan expert group who paid close attention to the epidemic, and carried out a patriotic health campaign in winter and spring in the whole city - cleaning up garbage and health dead spots, carrying out health education, banning live poultry market, killing rats and cockroaches, etc.

Chinas CDC launched a first-class response to public health emergencies Wednesday. This is the highest level of public health response, meaning things are particularly important..

As for whether or not human to human transmission is possible, the Wuhan Circular on January 16 was renamed not excluding limited human to human transmission, and the risk of continuous human to human transmission is low.

In an interview with science on January 16, Xu Jianguo, the group leader of the first group of experts from the national health and Health Commission and academician from China CDC, also said: This is a limited infection, and 763 close contacts have no disease.

On January 17, the Wuhan health and Health Commission did not report.

According to the report of Caijing on January 27, it was on that day that Yuan Guoyong, director of clinical microbiology and infection control department of Shenzhen Hospital of Hong Kong University, reported to Gao Fu, director of China CDC and Guangdong CDC in the form of written report the news that the new pneumonia was found in clinical cases. In addition, as a member of the high-level expert group of the new crown pneumonia national health and Health Commission, he also disclosed this information to other members of the expert group.

On that day, the two sessions of Hubei Province closed.

From 18th, Wuhan health and Health Commission adopted the method of notification every other two days: on 18th, it reported that on 16th, 4 new cases of pneumonia infected with coronavirus were detected and identified by using the diagnostic kit just issued by the state. 17 new cases were reported on the 19th. Two days of data were released on the 20th - 59 new cases on the 18th and 77 new cases on the 19th. On the 21st, 60 new cases were reported on the 20th and returned to the next day. At this time, 258 cases and 6 deaths were reported in Wuhan.

This is also the last time that Wuhan Municipal Health and Health Commission reported the epidemic information.

Wuhan officials later said that before January 16, there was no test kit in Hubei Province, and the process of case confirmation was: after clinical examination and consultation to confirm suspected cases, samples were transferred from districts, cities and provinces to the national designated testing agency in Beijing for virus separation and nucleic acid detection, and it took about 3-5 days to return the results. After that, the case samples were sent to the CDC of Hubei Province for testing. The testing time was shortened to about 2 days, and more than 200 samples could be tested every day, which seriously restricted the number and process of diagnosis in the future outbreak.

Is this an indirect response of Wuhan to the outside worlds doubts?
