Peking University's team worked out the emission transmission mode in COVID-19. How to avoid it?

Recently, a professor from Peking University Institute of Environmental Science and Engineering invited Sheng Mao's team to cooperate with Beijing Chaoyang District Center for Disease Control and Prevention to carry out research, which confirmed for the first time that human respiration itself is a very important way of emission and transmission in COVID-19, and most of the particulate matter in exhaled breath is less than PM2.5, thus further revealing the fact that aerosols spread and spread in COVID-19, and providing an important scientific basis for better blocking air transmission in the future. ?

First, personal epidemic prevention

1. Maintain good hygiene habits, pay attention to hand hygiene and wash hands frequently. When coughing or sneezing, be sure to cover your nose and mouth with a tissue or elbow, and don't spit everywhere.

2. Participate in the cleaning of green spaces, courtyards, public corridors, carports and other places inside and outside the community, and keep them clean and hygienic.

3. Cooperate with sanitation, property management and other institutions to increase the intensity of environmental sanitation and cleaning in the community, do a good job in the daily management of garbage bins (rooms), and remove sanitary corners. There are no livestock to keep.

4 enterprises and institutions as a unit, to carry out environmental remediation and cleaning activities inside and outside the workplace (public places).

5 play a leading role in the construction of healthy cells, and create a clean, healthy and orderly environment with health towns and health units as units.

Third, community epidemic prevention.

1. Improve rodent control facilities and intensify disinfection.

2. Citizens * * * participate in household rodent control, remove indoor and outdoor garbage, remove breeding grounds of vectors, and make garbage daily and daily. Clean up black and odorous water bodies and accumulated water in ponds, and eliminate overwintering mosquitoes and flies.

3. Cooperate with communities and professional prevention and control institutions to carry out rodent control in winter and spring, mosquito control and cockroach control in summer and autumn. Based on the principle of safety and high efficiency, poison bait is used to kill rats with drugs.

4. Each market adopts physical methods such as placing mousetraps, mousetraps and sticky boards in the market, standardizing the layout of bait stations outside the market, putting rodenticides and other measures to kill rats.
