Original title: The epidemic in Wangkui County, Heilongjiang Province has spread to many places, and most of the infected people gather for dinner

Located in Wangkui County, Suihua City, in the middle of Heilongjiang Province, it has a total population of about 500,000. This previously unknown place has recently become the focus of national attention because of the epidemic.

Since the asymptomatic infection of new coronary pneumonia appeared in Wangkui County on January 9, there have been sporadic epidemics related to it in many places. There have been more than 200 confirmed cases and asymptomatic infections, showing concentrated transmission in one place and spread across regions The situation.

“Xinhua Viewpoint” reporters found that at present, most of the new asymptomatic infections in Heilongjiang Province are confirmed cases in Huiqi Village, Huiqi Town, Wangkui County, close contacts and close contacts of asymptomatic infections, showing a wide spread range. , Strong concealment, difficulty in prevention and control, etc.

Most of the infected people gather for dinner, and the epidemic has spread to many places

At the moment, the lowest temperature is more than -20 degrees Celsius, and the streets and alleys of Wangkui County are deserted and pedestrians are rare. Citizen Li Min said that the epidemic broke out suddenly. In the past few days, all communities and villages in Wangkui County have implemented very strict closed management.

On January 9, Wangkui County People’s Hospital found a positive case in the outpatient checkup. Wang Mouhe, female, 30 years old. In the nucleic acid test of the close contact, 1 positive case was found, Zhang Mouyu, 10 years old, and 2 persons above are mother-child relationship. After review by the Suihua City Center for Disease Control and demonstration by the city and county expert groups, these two people were asymptomatic patients with new coronary pneumonia.

In the past few days, the number of confirmed cases and asymptomatic infections in Suihua City has been increasing, showing a trend of concentrated transmission. According to Dong Wenqin, Executive Deputy Mayor of Suihua City, as of 17:00 on the 14th, a total of 92 confirmed cases of new coronary pneumonia in the city, including 89 in Wangkui County and 3 in Beilin District; a total of 110 cases of asymptomatic infection, of which Wangkui County 104 cases, 2 cases in Suileng County, 1 case each in Anda City, Hailun City, Qinggang County and Beilin District.

According to the survey, most of the confirmed cases and asymptomatic infections in Wangkui County are villagers in Huiqi Village, Huiqi Town. They all gather and gather for dinner, which is highly correlated and clustered. The cases in Suileng County and Beilin District are related to those in Wangkui County. At present, Wangkui County has been included in the risk area of ​​the epidemic, and Huiqi Town has been adjusted to a high risk area.

Li Jie, a farmer in Wangkui County, said that the countryside is now entering the winter leisure period. At the end of the year, there are more marriages and more gathering activities. Usually everyone has relaxed prevention and control. Some villagers have recently participated in three or four weddings.

Sporadic epidemics related to Wangkui County have appeared in many places, showing a trend of cross-regional spread. On the 12th, there were 3 new cases of asymptomatic infection in Angangxi District of Qiqihar City, 1 case of asymptomatic infection in Daqingshan County of Yichun City, and 1 confirmed case in Xiangfang District of Harbin City. On the 13th, there were 4 new cases of asymptomatic infection in Linkou County, Mudanjiang City. These cases are all returnees from Wangkui County.

On the evening of the 13th, at a press conference on epidemic prevention and control held in Heilongjiang Province, Fang Qingwei, deputy director of the Heilongjiang Provincial Health Commission, said that there were 7 confirmed cases in Xiangfang District of Harbin City and Beilin District of Suihua City, and Angangxi District and Longsha District of Qiqihar City. The 19 cases of asymptomatic infections reported in the district, Linkou County of Mudanjiang City, Beilin District of Suihua City, Suileng County, and Daqingshan County of Yichun City were all close contacts and close contacts pushed by the Suihua City Center for Disease Control and Prevention. The investigation found.

In addition, the Jilin Provincial Health Commission notified on the 14th that 2 new cases of asymptomatic infection in Jilin Province on the 13th, all of whom were close contacts of imported asymptomatic infections in Wangkui County, were found through active screening. On the 13th, according to the Shandong Provincial Health Commission, a case of asymptomatic infection was found in Weihai City, who was a visitor from Wangkui County.

Difficulty in preventing and controlling asymptomatic infection

The state has previously issued the “Regulations for the Management of Asymptomatic Infectors of New Coronavirus,” which further regulates and clarifies the discovery, reporting and management of asymptomatic infections. Experts said that the epidemic situation in Wangkui County shows that the prevention and control of asymptomatic infections is still difficult.

At present, Wangkui County People’s Hospital and Suihua First Hospital have become designated hospitals. Li Xiaobo, deputy director of Suihua First Hospital, said that the minimum temperature in Heilongjiang in winter can reach minus 20-30 degrees Celsius, which is more suitable for the spread of the new crown virus. Asymptomatic infections have the characteristics of long-term latency, difficult detection, and secret transmission, making the epidemic difficult to detect, leading to a wider range of transmission, and increasing the difficulty of the current epidemic prevention and control.

Li Xiaobo said that judging from the situation of cases admitted to Suihua City, some asymptomatic infections only need to be isolated without drug treatment; some asymptomatic infections develop symptoms and become confirmed patients. Asymptomatic infections must be isolated for the first time for medical observation.

Relevant experts said that because asymptomatic infected people have no clinical symptoms, they are almost never discovered by active medical treatment. At present, they are mainly found through close contact screening, cluster epidemic investigation, and infection source tracking investigation. This has also become an epidemic. Difficulties of learning investigation. Judging from the recent clustered epidemics in Shijiazhuang and Suihua, they all initially occurred at the grassroots level, with relatively poor medical and health conditions and weak prevention awareness. Therefore, it is difficult to detect asymptomatic infections earlier.

The traceability of the epidemic situation in Wangkui County is still in progress. Dong Wenqin said that after the National Center for Disease Control and Prevention’s sequencing of the virus’s genes, the epidemic virus in Wangkui County is 100% homologous to the Dalian epidemic virus strain; whether it is transmitted from person to person or from material, further research and judgment through epidemiological investigation is needed.

Continued upgrade of control measures and increased nucleic acid testing

On the morning of the 11th, Li Zexin, a resident of Shuanglong Community in Wangkui County, began to line up for nucleic acid testing, and medical staff were sampling throat swabs for citizens. Qian Xiuli, deputy secretary of the Party branch of Shuanglong Community, said that all the staff arrived at 8 am, organized residents to wear masks, and arranged for residents who had finished nucleic acid to leave in time.

In order to do a good job in the testing of all employees, Suihua selected 860 people from the city to form ten sampling and testing teams to quickly carry out nucleic acid sampling and testing. The reporter learned from the Suihua City Headquarters for the Prevention and Control of the New Coronary Pneumonia Epidemic that after 2 days of non-stop work, the first round of sampling in Wangkui County has been completed, and 247,904 samples have been collected. The second round of nucleic acid testing is currently being conducted on personnel from Huiqi Town and Dalian to Suihua. Sampling and testing in other related counties (cities) and districts are also in progress.

At present, Suihua City implements strict control. From 15:00 on the 12th, all entrances and exits in the main urban area of ​​Suihua City will be closed, and only one emergency road will be reserved for the passage of motor vehicles in each township and village; the waiting hall and entry passages of the railway station are closed, and passengers are prohibited from entering the station. Exit personnel carry the nucleic acid test report within three days, and are allowed to pass after wearing a mask, scanning the code, and measuring the temperature. Suihua City’s buses, long-distance buses, and Tongxiang-tongcun passenger vehicles are all suspended. Taxis are limited to urban areas, and the people in the vehicles are physically separated.

After receiving the report of the epidemic in Wangkui County, Heilongjiang carried out investigations of risk personnel across the province. Focusing on key epidemic areas in the country and the province, we have carried out comprehensive investigation and control of risk personnel through multiple channels. The outflow personnel in Wangkui County in the past 14 days have been sent to local epidemic prevention and control headquarters for one-by-one verification.

Fang Qingwei said that in the next step, Heilongjiang Province will effectively play the role of primary medical and health institutions as sentinels, focusing on the prevention and control of epidemics in rural areas. In response to the recent frequent outbreaks of rural epidemics and weak prevention and control capabilities, a three-level command system at county and village levels and a subcontracting mechanism have been established to strengthen the inspection and control of migrants in rural areas, and conduct targeted nucleic acid testing on returnees. Strictly control various gatherings of people such as weddings and funerals, banquets, chess and entertainment, and minimize the flow and gathering of people.

Sun Dianjun, director of the Key Laboratory of Etiology and Epidemiology of the National Health Commission, said that in this Wangkui County epidemic, the asymptomatic infection was initially found in Wangkui County People’s Hospital who found positive nucleic acid during the outpatient checkup. This is the embodiment of the sentinel role played by medical institutions. At present, it is necessary to strictly implement due diligence in key areas such as medical institutions, airports, and rural areas, and in particular, further strengthen the reporting system of epidemic detection in township health centers, village clinics and individual clinics. This helps to quickly discover hidden asymptomatic transmission chains and rob time for epidemic prevention and control.
