The main routes of transmission in COVID-19 are droplet transmission and contact transmission. It is meaningless to use drones for air disinfection in outdoor spaces such as residential areas, streets and squares.
ground
Viruses can survive for a long time by entering human cells to absorb nutrients. Public ground and green plants need not be disinfected if they are not polluted by vomit, secretion and excrement.
wheel
There is almost no virus on the outer surface of the car, including the body and wheels. In some places, it is over-disinfection to spray disinfectant on wheels when vehicles enter communities or units.
sole (of the foot)
After the water drops are deposited, even if the shoes may be infected with the virus, the amount is very small. There is no need to disinfect the soles in daily life, just keep them clean. It is recommended to change shoes at the door after returning home.
surgical mask
Spraying masks with medical alcohol and disinfectant will reduce the protection efficiency. Heating the mask with microwave oven, electric oven or steamer will destroy the internal structure of the mask, and it is not recommended to use it again.
Community "disinfection shed"
In some residential areas, a "disinfection shed" is built at the door, and it is potentially harmful to people's health to spray disinfectant directly on them.
Air purifier
Air purifiers are mainly used to remove one or more pollutants in the air, and there is no requirement for the killing rate of viruses or other pathogenic microorganisms, so they may not be able to filter viruses.
stay at home
If there are no patients at home, family members seldom go out to eat and there are no outsiders. There is no need for excessive disinfection, and it is mainly clean and hygienic.
What about disinfectant poisoning?
Respiratory inhalation contact, immediately out of the toxic environment, into the fresh air.
If it comes into contact with skin and mucous membrane, rinse it repeatedly with plenty of running water immediately 10 minutes or more.
Oral contact, oral milk, rice porridge, etc. Can protect gastrointestinal mucosa.
If the exposure dose is large, or the symptoms continue to improve, you should seek medical attention immediately.
