American Center for Disease Control and Prevention (CDC) revised its guidelines for Americans to wear masks Friday, saying all Americans should wear masks when they go out in public to avoid spreading the new crown virus.However, medical masks, including surgical masks and N95 masks, should still be retained for medical staff. and the proposal to wear masks is not mandatory.
According to CDC new guidelines, ordinary citizens should wear cloth masks when they go out, whether or not they are ill. These masks can be cleaned and reused. Some infected people have no symptoms and will spread the virus to others without knowing it; homemade and other cloth masks can help prevent it. At the same time, people wearing cloth masks should take the same precautions as before, including keeping social distance, washing hands, etc.
Before the CDC said that ordinary citizens do not need to wear masks, unless sick or care for sick people, do not need to wear masks. The new CDC guidelines do not mean that people should rush to find N95 masks – which are in short supply and are needed by first-line health workers in the pandemic. Conversely, CDC think people should use other cloth masks or homemade masks. For homemade masks, some health centers recommend the use of four-layer cloth masks to better block particulate matter.
CDC also pointed out that even if people wear masks, they should keep at least six feet away from others, avoid group gatherings, go out only when they are outdoors and purchase necessities of life, and wash their hands when they go home.
