Not gathering! No more! Recently, the proportion of clustering epidemics is rising, and the epidemic situation is still grim. Governments everywhere are also asking the public to reduce their aggregation.

In February 4th, a press conference was held in Harbin. As at 24 hours in February 3rd, 63 cases of pneumonia confirmed by new coronavirus were reported in Harbin. Among the 63 confirmed cases, there were 10 clustered epidemics involving family gatherings, meals and close personnel contacts. The total number of cases was 37, accounting for 58.7% of the total number of cases.

In February 3rd, a press conference was held in Beijing to introduce the current epidemic situation of new pneumonia. Up to 24 in February 2nd, 212 confirmed cases of new pneumonia in Beijing were found, and 41 cases were clustered, involving 124 people.

With the transition from inward to diffuse, many epidemic cases were revealed in government press conferences and epidemic bulletin, especially in family gatherings. In twenty-first Century, the economic report combing reporters found that there were family clusters in many provinces and cities including Anhui, Hainan, Guangdong, Qingdao, Beijing and Harbin.

He Xiong, deputy director of Beijing City Center for Disease Control and prevention, pointed out that aggregation activities are the main factors leading to the cluster epidemic. The prevention and control of cluster epidemic is the key and difficult point of Beijing epidemic prevention and control. "Clustered epidemic" refers to the discovery of 2 or more confirmed cases in a relatively small area, such as a family, class, and construction site within a latent period, and the possibility of interpersonal communication caused by close contacts or the possibility of infection due to joint exposure. Once the outbreak occurs, people around will be threatened, and community prevention and control is facing new challenges. "

Frequent occurrence of familial epidemics

As of 24 February 2nd, a total of 41 cases of clustering were reported in Beijing, involving 124 cases, accounting for more than 50% of the confirmed cases. As of noon on February 2nd, there were 60 epidemic cases in Shandong province. As at 24 o'clock in February 3rd, Harbin reported 63 cases of pneumonia diagnosed by new coronavirus, with 10 cases of clustering, with a total incidence of 37, accounting for 58.7% of the total number of cases.

In addition, according to the twenty-first Century economic report, a number of clustered epidemics have also occurred in many provinces and cities such as Anhui, Hainan and Tianjin.

Among them, the prevalence of family aggregation is especially prevalent.

As of February 3rd, 12 congregated outbreaks occurred in Hainan Province, mainly in family members, especially among older people. At the same time, the incidence of low age group in Hainan was the lowest. The minimum age was 3 months. In Shandong, 60 cases of cluster epidemic had been found, 49 of which accounted for more than 8.

In February 4th, according to the bulletin of the Ganzhou municipal health and Health Committee, there were 5 family cluster epidemics in Ganzhou, involving 29 cases, and family infection in Zhanggong District, Ganxian District, Huichang county and Quan Nan county. Of the 11 newly added cases in the last 3 days, 4 were imported cases and 7 were family clustered cases.

Kou Zengqiang, director of the Shandong Provincial Center for Disease Control and prevention of viral diseases, said the cluster epidemic had a great impact on the overall epidemic situation in Shandong. Shandong CDC conducted laboratory sampling tests on some close contacts, and reported 14 cases of asymptomatic infections. This aspect shows that the new coronavirus has strong transmission ability, and on the other hand, it also indicates the difficulty of late prevention and control.

Kou Zengqiang introduced a cluster epidemic. K1068 times is a green train from Hubei Wuhan Hankou to Shandong Weihai, because the green car carriage is not well ventilated and has a long driving time, exposing the risk very high. Epidemiological survey showed that in Weihai, 24 cases were confirmed, 2 cases were crew members and 8 were passengers, 6 of the family members were 16, and only 66.67% of the cases were diagnosed.

No accumulation, no accumulation

Up to now, 31 provinces and municipalities have launched a major public health emergency response, epidemic prevention and control is being comprehensively promoted, and prevention and control efforts continue to increase.

But with the end of the Spring Festival holiday, people from all over the countryside returned home. Even if the passenger flow keeps low, it is still more than 10 million passengers per day. The new coronavirus infection epidemic prevention and control work is ushering in a new challenge.

In February 3rd, Bao Changjun, a member of the Jiangsu provincial health and Health Committee, a member of the expert group on pneumonia prevention and treatment of new coronavirus, and director of the provincial emergency center of the Jiangsu Provincial Center for Disease Control and prevention, said that at present, the incidence of clustering epidemic is increasing in the stage of the generation of cases and the secondary cases in the cross incidence stage, and the epidemic situation is still grim.

Bao Changjun pointed out that from the current reported cases in Jiangsu, the number of reported cases of cluster epidemic is also increasing, suggesting that the risk of community communication is increasing.

"Now we also find asymptomatic and mild cases. These people may be contagious, but he has no clinical symptoms or mild clinical symptoms, so it is difficult to detect them in time and effectively isolate them, so they are also called "mobile sources of infection". There are still some cases that are contagious before the obvious symptoms, that is, the so-called "latent infection". Their transmission is of a certain degree of concealment and complexity. All these conditions increase the difficulty of our current epidemic prevention and control, and also remind us not to relax your vigilance. Bao Changjun said.

Hsiung hung also pointed out that aggregation activities are the main factors leading to the cluster epidemic. The prevention and control of cluster epidemic is the key and difficult point of epidemic prevention and control in Beijing.

Bao Changjun suggested that for individuals, we should try our best to go out as little as possible and take part in some clustered activities. For example, we also have this kind of clustering epidemic, which is caused by playing mahjong in the community activity center for the elderly. For our communities and units, if it is not necessary, try not to host some large-scale activities, such as gatherings, meetings, etc.

For the return peak, Feng Zijian, deputy director of the China Center for Disease Control and prevention, suggested that self health status be detected for 14 consecutive days from the time of leaving the epidemic area, and 2 times a day. In addition, community health workers will contact the return workers to see if there is any change in their health. When conditions permit, try to live alone, or live in a well ventilated room, minimize close contact with family members, reduce outings, and avoid crowded activities in public places. If there are suspicious symptoms such as fever and cough, timely treatment should be made according to the condition.

In fact, various governments have taken various measures to prevent the further occurrence of the epidemic. If the afternoon of January 29th, the Beijing municipal housing and Urban Rural Construction Committee responsible person said that the construction site will be strictly controlled to resume working hours, requiring the city's housing construction and municipal infrastructure projects not earlier than 24 February 9th to resume work.

At noon in February 3rd, the Shandong provincial market supervision and Administration Bureau also issued an urgent circular on the prevention and control of pneumonia caused by new coronavirus infection by the catering service providers, requiring all catering units to stop receiving large scale meals, encouraging "contactless" distribution, resuming the unit to take preventive measures such as box lunch, room service, etc. the total temperature of cooked food center must reach 70 degrees Celsius and so on, and there are altogether 12 measures.

In February 4th, the Hefei City CDC reminded people that a new coronavirus is mainly through respiratory droplets and close contact to achieve "human to human" transmission. An important measure to prevent and control the new coronavirus infection is pneumonia.
