Beijing nucleic acid positive man refused to admit that he had eaten in a roast duck restaurant related to the epidemic. How many people have been infected by his transmission chain?

The pressure of prevention and control continues to increase, and epidemic prevention and control is in a critical period. It is necessary to adhere to precise prevention and control, dynamic clearing, compaction of the responsibilities of the four parties, early detection and early treatment, and effectively control the spread of the epidemic at the least cost. Omicron mutant is highly contagious and spreads quickly, which increases the risk of serious diseases due to advanced age, combined with basic diseases or not vaccinated. The epidemic in Beijing involved nine elderly people aged 60 and over and two children aged 12 12. Some elderly people take medicine by themselves after symptoms appear, and do not seek medical treatment in time, which not only harms the health of others, but also increases the risk of epidemic spread.

Schools, old-age care institutions and other crowd gathering places and units strictly implement prevention and control measures, strengthen closed-loop management of personnel, and do a good job in nucleic acid testing according to the epidemic situation, risk personnel and risk points. In particular, the elderly and children should have symptoms such as fever, dry cough, expectoration, sore throat, fatigue, diarrhea, abnormal taste and smell, and are not allowed to buy or take medicine by themselves, take public transport, use the internet car, and seek medical treatment in time according to regulations.

A person who tested positive for nucleic acid in Beijing once concealed that he had been to a roast duck restaurant related to the epidemic and was put on file for investigation. The person with positive nucleic acid test went to Yu Le Xuan Roast Duck Restaurant for dinner on March 10. After the epidemic occurred in Yulexuan Roast Duck Restaurant and informed the society of the activity track of the infected person, when accepting the community investigation, they refused to admit that they had been to Yulexuan Roast Duck Restaurant, which endangered their own health, interfered with the tracing of the source of infection and the determination of the scope of close contacts, and increased the risk of epidemic spread. Relevant departments found in the epidemic investigation of Le Xuan Roast Duck Restaurant that Liu Moumou, male, 66 years old, and other six people had dined in the restaurant and had close contact with the confirmed case Wang Moumou at the same time.

Liu is suspected of obstructing the prevention and treatment of infectious diseases. He has been investigated by the police and dealt with according to law after being cured. In the process of tracing the source of flow control, the disease control department found that Yu Le Xuan Roast Duck Restaurant failed to implement epidemic prevention measures such as scanning and registration of health code and temperature detection. Of the 830 people who came to the store, 477 did not scan the registration code, which seriously hindered the follow-up epidemic prevention measures such as people tracking, personnel management, isolation and transportation. Yulexuan roast duck restaurant has infected 1 1 person, which has seriously damaged the health and life safety of citizens.
