The fourth wave of the new crown pneumonia epidemic is fierce, and local and unsourced cases continue to increase. The government has once again tightened epidemic prevention measures, including tightening the gathering order to two people, and the closure of game consoles and entertainment venues.
However, asymptomatic patients are by your side at any time, and everyone can only do their best to prevent the epidemic.
Anti-epidemic methods that claim to be able to withstand the new crown pneumonia are flying everywhere, such as spraying disinfectant alcohol at home from time to time, or diluting bleach with hot water will have a better disinfection effect. Which ones are correct and which are wrong?
Let's summarize the wrong methods of epidemic prevention together, so as not to be self-defeating and backfire!
The increase in the sourceless cases of new coronary pneumonia has raised concerns about the invisible transmission chain in the community.
Although many people have increased their awareness of epidemic prevention during the epidemic, in addition to wearing masks, the correct use of disinfectant alcohol and bleach is also important; otherwise, it will not only waste energy, but also let the virus take advantage of it in minutes!

1. Spray alcohol or chlorine all over the body for disinfection
The use of chlorine and alcohol can effectively disinfect the surface, but it cannot kill the viruses that have entered the body. It can also damage the mucous membranes of the mouth and eyes.
When spraying, open flames must be prohibited to prevent excessive concentration and increase the risk of burning.
If really necessary, it is best to spray in an open place or outdoors before entering the house.

2. The higher the concentration of disinfectant alcohol, the better
To kill 99.9% of bacteria, the alcohol content must reach 60% or more, but high-concentration alcohol (95% or more) will cause the protein on the surface of the bacteria to condense to form a dura mater, which instead protects the bacteria.
Studies have pointed out that 75% alcohol can have both protein coagulation and penetrating effects, and the most rapid and thorough sterilization effect can be achieved.

8. Open the toilet board to flush the toilet
Some patients with new coronary pneumonia will have diarrhea, and the virus has been confirmed to survive in the stool.
