Wear masks of medical grade and above in public environment to deal with delta virus
Wearing an ordinary mask can not avoid virus infection in a closed environment for a long time. Wearing a medical protective mask can greatly improve the respiratory protection effect and reduce the infection rate.
In the view of experts, at present, the "delta" mutant is popular all over the world and has the characteristics of fast transmission and strong infectivity. Therefore, timely revision of the guidelines for wearing masks will form a more effective protection for the public.
For example, salespeople, ticket sellers, police, chefs, hotel and restaurant waiters, couriers, cargo distributors, doorkeepers, security guards, cleaners, etc. wear medical surgical masks or above throughout the work.
