First, plan ahead.
1, vaccination
Vaccine is a "protective shield" against COVID-19, so it is recommended to vaccinate as soon as possible, especially for high-risk groups.
Step 2 put on a mask
People in many places seldom pay attention to wearing masks, but do you know? The probability of wearing a mask with a positive infected person can be greatly reduced. According to @ Time Video;
(1) If you don't wear a mask, the risk of infection is 90%;
② If you wear a mask, the infection risk of a positive person without a mask is 30%;
③ If you don't wear a mask, the infection risk of positive people wearing a mask is10%;
④ All of them wore masks, and the infection risk was1.5%;
⑤ All of them wear masks, and the distance is more than 2m, so the risk of infection is 0%.
So wearing a mask can keep the virus out to a great extent.
But for the choice of masks, many people have made it difficult. I don't know if N95 should always wear anti-virus.
Zhang, secretary of the Party Committee of Guangzhou Center for Disease Control and Prevention, said that except in special circumstances, it is not necessary for citizens to wear N95 masks when they go out every day, but medical surgical masks can.
Therefore, for the choice of masks, everyone can scientifically reserve them as needed.
3, diligent disinfection
COVID-19 can survive on the surface of objects, so after touching public goods or going home, we should pay attention to disinfection, and it is best to choose 75% alcohol for disinfection.
