Experts from epidemic prevention and control 丨 Wearing a mask to be alert to the transmission of gas solitude

"The existing research has confirmed that in the relatively closed space, the new coronary virus, especially Omikon, can be transmitted through gas solution." Yang Hongcai, director of the Control Center, said.

The air -soluble is a uniform and stable dispersion system formed by solid or liquid particles in the gas medium. Its particle size is generally 0.001 microns -100 microns. Smoke and fog are common air -soluble gums. The air -soluble gels formed by the decentralized system in the decentralized system are usually called fog, and gas -soluble gums formed by solids are usually called smoke.

When people breathe, speak, and cough, they can release a large amount of air -solubled oscorion particles. The tiny air -soluble gel particles will be suspended in the air and survive for several hours because they are not gravity. When the sensible person is exposed to the enveloped area of ​​the air -soluble glue, there is a risk of inhaling infection.

The concentration of gas solution is the highest in the environment near the release. As the distance from the source of infection increases, it will gradually be diluted by air. It will also be affected by factors such as temperature, humidity, and ultraviolet radiation.

In a well -ventilated space, only air -soluble gum transmission occurs at close range; but in poor ventilation or crowded environment, whether it is close or long -distance susceptible, it is in the risk of infection.

"At present, there are three main ways to spread the new crown virus." Yang Hongcai said, one is to spread through the respiratory tract droplets and close contact; the other is to spread through gas solution in a relatively closed environment; the third is to contact the infection of items contaminated by the virus. In different spaces and scenarios, all transmission pathways can play its role, which can be independent, or may be a synergy.

Yang Hongcai suggested that out -of -person personnel regulate wearing masks, unnecessary do not go to the crowd -intensive places, talk to people to maintain a safe social distance of more than 1 meter, do a good job of hand hygiene, and develop good hygiene habits.

During the home, open windows to ensure indoor air circulation; You can use plastic bags to irrigate tightly, put it on the floor drain, and block the floor drain; cover the toilet cover before flushing the toilet to avoid air -soluble splashes outside the toilet; when you open the range hood to cook Flowing flow of air flow; develop good sanitation habits, do a good job of indoor hygiene and cleaning; try to keep the distance as much as possible and wear a mask.
