Zhong Nanshan, Li Lanjuan and Zhang Wenhong participated in the video report of the experts in the prevention and control of the epidemic of the Ministry of Education and pointed out that the
school resumes school, and there is no need to panic if there are individual cases.
"I actively support the resumption of classes, but do enough measures to maintain a certain social distance." On the afternoon of April 20, at the video conference of the expert report on school epidemic prevention and control hosted by the Ministry of Education, academicians of the Chinese Academy of Engineering and the National Respiratory System Zhong Nanshan, director of the Clinical Medicine Research Center for Diseases, emphasized that the work of returning to school must be advanced. Even if there are cases of infection in individual schools, it is not surprising that if problems are dealt with in a timely manner, there will not be a large-scale outbreak in the school.
As of April 17, all provinces (autonomous regions and municipalities) in our country, including the Xinjiang Production and Construction Corps, have at least specified the start time of some semesters, and the number of returning students has reached more than 35 million.
How to prevent and control campus epidemic situation under normal epidemic prevention and control? The Ministry of Education opened a luxurious lineup of "comrades" in the national education system. Invited experts Zhong Nanshan, Academician of the Chinese Academy of Engineering Li Lanjuan and Director of the Infection Department of Huashan Hospital Affiliated to Fudan University Zhang Wenhong "pulse" for the school's resumption of work.
China still faces input risks for a long time
The spread of the new epidemic pneumonia in China has been basically blocked. However, China still faces a greater risk of overseas imports.
"At first glance, among a small number of people, only a few percent of them have antibodies to the new coronavirus. If there is a large number of imported infections, we are certainly not immune." Zhong Nanshan pointed out that China's anti-epidemic disease Life safety and physical health are put first, and the mechanism of joint prevention and joint control has achieved good results. However, the international epidemic situation is not optimistic. "Secondary external infections exist at any time."
Some countries are in the peak frequency of the epidemic; some countries have not yet reached the peak and the epidemic is still spreading; others, because the current detection capabilities can not keep up, the epidemic situation is unknown.
"The biggest risk facing schools is also the input risk." Zhang Wenhong said, "This risk will always exist in the coming months."
Imported cases may cause individual cases in the country. Once an individual case occurs, it may be associated with the school. In universities, local students have to go home at night; in primary and secondary schools, parents will contact the outside world. Another problem is the small number of asymptomatic infections.
However, the three experts clearly pointed out that no matter which city in China has a case, even if this case has a small spread, even a super spreader is normal.
It is not the school ’s responsibility if patient 1 appears in the school
"The key to prevention and control in schools is not to allow second-, third-, or even fourth-generation cases to form serial infections in your school." Zhang Wenhong bluntly said that if there is a case 1 in the school, the responsibility must not be in the school. It is the job of health and disease control systems to detect and diagnose cases of associated infection. However, if a large number of secondary and tertiary transmissions appear in schools, it is likely that the school's epidemic prevention work has not been done well.
Thousands of prevention and control, the distance from the first. Zhang Wenhong said that after school resumes, teachers and students must maintain a physical distance in the society and use alternative solutions to address the social needs of students.
How to keep the distance? From classrooms to restaurants to dormitories, different scenarios should have corresponding plans. In the management of dormitory, students can not come to the door; dining in the restaurant must be separated; in class in the classroom, you can consider splitting one class into two to give students more space ...
Zhang Wenhong also suggested that the school should establish contact with fever clinics of nearby hospitals. Once the students have a condition, they can be sent to the designated hospital for diagnosis to form a closed management loop.
"The school's prevention and control, one is to have a social distance, and the other is to have an effective emergency prevention and control process." Zhang Wenhong said that as long as the process is strictly followed, even if there are individual infection cases, it will not cause serious consequences. .
Li Lanjuan stated that she actively supports the resumption of school, but when the school resumes, it must be "clear chassis". Make sure there are no infected people in the school and there is no source of infection in the school. If you are worried about people who come back from key areas, you should conduct nucleic acid testing and even antibody testing. Li Lanjuan pointed out that schools in border provinces should be more vigilant.
"Keep your distance, wear a mask, wash your hands frequently, and measure your body temperature ... Once you find the source of infection, immediately isolate the person you are in contact with, without causing a large spread and without panic." Li Lanjuan emphasized.
