The cumulative number of confirmed cases in this round of the epidemic is still rising.
"Wedding banquet", "super communicator", "small clinic", "online ride-hailing driver", "small dining table"... Some keywords appearing in the itinerary of confirmed cases all hint at prevention and control loopholes and hidden risks.

Risk 1: Get together at banquets and wedding banquets
In the itinerary of confirmed cases announced in this round of the epidemic, words such as "wedding banquet" and "party" appear frequently.
At the end of the year, various banquets gathered together in various places, especially in rural areas, which also provided a breeding ground for the spread of the virus.
In Hebei, there has been a case of a wedding banquet with multiple confirmed cases; in Wangkui County, Heilongjiang, most of the confirmed cases and asymptomatic infections are villagers in Huiqi Village, Huiqi Town, and they all gather for dinner, which is highly related. And aggregation.
Recently, many places have made regulations on family gatherings and funeral events during the Spring Festival.
The National Health Commission has also issued a reminder: It is recommended to hold weddings and other activities in a civilized manner during the festival, and try to put as few seats as possible to avoid crowds.

Risk 2: Large-scale gathering activities
The "Notice on Doing a Good Job in the Prevention and Control of the New Coronary Pneumonia Epidemic During the New Year's Day and the Spring Festival in 2021" issued by the Comprehensive Group of the Joint Prevention and Control Mechanism of the State Council earlier stated that it is advisable to limit family private gatherings to less than 10 people; activities with more than 50 people should be formulated Prevention and control plan.
However, the recently announced trajectory of cases shows that after New Year's Day, large-scale gatherings are still being held in some places, and "super spreaders" have appeared.
On January 13, Jilin Province notified an asymptomatic infected person with new coronary pneumonia. He had conducted training and lectures in different locations, which in turn caused group infections.
As of 14:00 on January 17, this "super spreader" has caused 102 local infections.
According to official reports, from January 6 to 11, less than a week, the case carried out four marketing campaigns targeting middle-aged and elderly people in Gongzhuling City and Tonghua City.
Previously, there was a 33 "super spreader" in Dalian, Liaoning. This super spread originated from a family gathering: Case Jin infected all 11 people through a family gathering, and then spread to the corridor where they lived. Unit households and other social contacts.
In addition to the above cases, in Beijing, two consecutive children were diagnosed with the same "small dining table".
Observing the super-spreading chains that have emerged, it is not difficult to find that "super-spreaders" tend to have intensive social activities in a short period of time and reach a wide range of people.
Feng Zijian, deputy director of the Chinese Center for Disease Control and Prevention, has issued a reminder: Super transmission often occurs at parties, banquets, or other social occasions.
He emphasized that more measures must be taken, more suggestions to the public, fewer gatherings, and smaller gatherings.

Risk 3: paralysis in the primary clinic
In this round of the epidemic, the paralysis of some primary medical institutions has also caused the first "sentinel point" to not fully play its role.
For example, in the epidemic in Hebei, some confirmed cases had fever many days before the diagnosis, and they had seen many times at a local clinic in Xiaoguozhuang Village, but they did not undergo nucleic acid testing immediately.
In addition, a 66-year-old man who opened a clinic in Xiaoguozhuang Village was also diagnosed with the infection.
In Beijing, there has also been a problem of transfusion of confirmed cases to "black clinics".
The confirmed case in Shunyi District had symptoms of dry throat, sore throat, and headache since January 2, and he went to the "black clinic" for infusion treatment for three consecutive days.
The person who provided the infusion for this case turned out to be engaged in illegal diagnosis and treatment activities without obtaining the qualifications of a physician.
When receiving patients with cough, fever, etc., diagnose and prescribe drugs without authorization, and do not report the condition of patients with fever as required.
In response to loopholes in the prevention and control of primary medical institutions, many places have successively made deployments.
Hebei proposed to prohibit village clinics and individual clinics at the grassroots level from receiving patients with fever.
Heilongjiang requires primary medical institutions to implement the first-diagnostic responsibility system and report suspected cases such as fever and cough to the township hospital within 2 hours.

Risk 4: Internet ride-hailing drivers are frequently "recruited"
Among the confirmed cases discovered recently, a "sensitive" occupation has emerged-online car-hailing drivers.
Since the end of December 2020, there have been multiple confirmed cases of ride-hailing drivers in Beijing.
In Shijiazhuang, Hebei, there have also been cases where the confirmed person had driven a taxi for several days.
A wide range of activities and a large number of close contacts... Once an online ride-hailing driver is infected, it will become a major hidden risk.
For example, the number of close contacts of a ride-hailing driver diagnosed in Beijing on January 9th exceeded 350, among which hundreds of passengers were involved.
Recently, Beijing has inspected relevant online car-hailing platforms and investigated and dealt with multiple cases of illegal activities involving online car-hailing platforms. Some platforms have fined more than one million.
Several online ride-hailing platforms have also made it clear recently that they will take a number of measures to increase the prevention and control of the epidemic, including organizing their ride-hailing drivers to vaccinate the new crown.
Starting from January 13, drivers under some Beijing ride-hailing platforms have been vaccinated against the new crown pneumonia at vaccination points in Beijing.
The number of drivers booking vaccination exceeds 100,000.
On January 9, the passage from the Shijiazhuang Railway Station platform to the exit was closed.

Risk 5: The train carriage is also a "high-risk" environment
Studies have shown that the new coronavirus spreads as far as 4.5 meters in air-conditioned vehicles, and the virus can float in the air for at least 30 minutes and cause infection.
In the current round of the epidemic, multiple COVID-19 patients were found in the same compartment.
The 5 cases of asymptomatic infections recently notified by Jilin Province all took the K350 train from Jiamusi, Heilongjiang to Beijing on January 5, and the seats were all in car 11, car 11, No. 27, No. 28, No. 19, and No. 20 And number 13.
Zhang Yu, an associate researcher of the Chinese Center for Disease Control and Prevention, analyzed in an interview with the media a few days ago that the virulence and pathogenicity of the new coronavirus itself are certain, but in different environments, the transmission capacity is different. Under outdoor ventilation conditions , The infectivity may be reduced, but under confined conditions, such as in the car or in the cabin, the risk of infection will increase due to obstructed air circulation and high density of people.
According to media statistics, since January 2021, there have been at least 10 cases of infected persons who have travelled by train or high-speed rail.
The Spring Festival travel season is approaching, and in the face of the largest population movement in a year, how to minimize the risk of the spread of the epidemic will test everyone.
