Why don't CDC recommend people to wear masks to prevent COVID-19?

At present, the global epidemic situation is on the rise, and various countries have introduced various measures to control the epidemic situation. Not long ago, the CDC published an article saying that people who are not infected can wear masks, which makes us a little puzzled after wearing masks for more than a month. Since we know the seriousness of droplet transmission, why not wear a mask? This is related to the inherent habits of Americans and the national mask reserve.

In the eyes of many foreigners, only patients wear masks. At present, many overseas Chinese are deeply touched by this. In the inherent logic of foreigners, masks are used to prevent patients from spreading saliva. After wearing a mask, your mouth is sealed, not others', so wearing a mask actually protects others, not yourself. This is not wrong in logic, but it is not quite right in any way. In addition, the US government has been playing down people's fear of the epidemic. If everyone on the road wears masks abnormally, the official media will not be able to justify themselves and will easily cause panic.

In fact, in the final analysis, it is not that they are unwilling to wear masks, but that there are not so many masks in the United States. European and American countries do not have the habit of wearing masks themselves, which means that the stocks of masks in the countries themselves are not enough. Judging from the news in the past two days, the masks in the United States can't even be guaranteed by medical staff, and the gap is huge. In addition, there are not many manufacturers of civilian masks in the United States. If you need a lot of masks, you can only import them. This kind of import at this time undoubtedly exposes the terrible epidemic, which the official does not want to see. Moreover, if the whole people start wearing masks, the gap of masks for medical workers will be even greater, and citizens will be more anxious because they can't buy masks, and the consequences will be unimaginable.

Therefore, at present, it seems that the reason why people in the United States do not wear masks is related to the stock and output of masks. In addition, the price of masks has been rising in recent years. I think even if Americans buy at this time, they may not be able to buy the normal price. On the contrary, they will protest against the government because prices have risen sharply. In this way, it is still quite difficult to get old.
