Do you need a mask to go to CDC
you only need to bring your ID card
of course, they have to audit it
it's OK for ordinary people who have no disease.
The U.S. Centers for Disease Control and Prevention (CDC) calls for people to wear masks, but it is not to let Americans wear masks with breathing valves, because such masks can not prevent the spread of the virus
to put it bluntly, if this mask can't prevent the spread of the virus, then it's meaningless to wear it, on the contrary, it affects daily life however, some people think that the respirator with breathing valve seems to be more professional and more powerful, and it seems to have more protective effect than the ordinary respirator, so they take the respirator with breathing valve to the street. After the CDC found this phenomenon, it immediately banned it, saying that this kind of respirator can not prevent the spread of infectious diseases
At present, the global epidemic situation is on the rise, and various countries have launched various measures to control the epidemic situation. Not long ago, the United States Centers for Disease Control and Prevention published an article saying that people who have not been infected can not wear masks, which makes us a little confused after wearing masks for more than a month< why we know the seriousness of droplet transmission, but still do not recommend wearing masks? This is related to the inherent habits of Americans and the national mask reserves
therefore, at present, the reason why CDC in the United States makes people not wear masks is still related to the stock and proction of masks moreover, the price of masks has been rising in recent years. I think even if the American people are allowed to buy them, they may not be able to buy them at normal prices. On the contrary, they will protest against the government because of the sharp rise in prices, right? In this way, Lao Mei is also quite difficult
The purpose of opening the window is to let the air circulate, ventilate 2-3 times a day, half an hour each time, can dilute a large number of viruses in the environment, so that the virus can not play a pathogenic role in the human body
influenza virus can survive in the air for several hours in the form of droplets, and low temperature will increase its viability. However, influenza virus in the hands of survival time is very short, about five minutes the number of viruses on the hands will drop to a very low level
It is very important to keep good hand hygiene and disinfect the surface of commonly used articles regularly to slow down the spread of influenza virus when the epidemic situation of influenza virus is rampant, such as influenza season. Using certain concentration of bleach, vinegar, detergent or antibacterial rag to clean the surface of articles can effectively rece the activity of influenza virus
