Researchers in Mexico have introduced a mask that only covers the nose and explained this? Masks are designed to reduce the risk of COVID-19 virus infection while eating.

Is this researcher's idea good? I hope the diet epidemic prevention is correct? But there is a nose mask hanging on both ears, which looks strange and feels a bit like the king in poker.

The key is to pity both ears, wear this nasal mask inside and a normal mask outside. This burden seems a bit heavy. By the way, if you wear another pair of glasses, should your ears cry? Is it too difficult to have a baby? .

Even if it looks beautiful, I won't buy it because I think it's useless.

I mean, are we wearing so much? Cover? What is this for, not just to avoid COVID-19 infection, then we should know what is the route of infection in COVID-19.

For example, COVID-19 can spread through respiratory droplets and close contact, but it can also be infected if it touches the surface of a contaminated object. I want to ask, can covering your nose really reduce the risk of infection?

Does the World Health Organization explicitly wear masks in its recommendations? To prevent COVID-19 infection, you need to cover your nose, mouth and chin at the same time? Covering your nose is definitely not reliable.

Imagine if a healthy person and an infected person were eating at the same table in COVID-19. Although both of them are wearing masks that only cover their noses, what happens if the infected person sneezes and the droplets fly into the eyes of healthy people?

Healthy people are likely to be infected with COVID-19, because the virus is likely to enter the body of healthy people through the cornea of healthy people, so I feel this so-called? Mask? It's useless.

Proper protection is the last word, and the rest is just the eye of bloggers.

Epidemic prevention has become a normal state, but we must not relax our vigilance. Wearing a mask correctly every day and doing personal and family disinfection every day are important means to protect yourself and your family.

Of course, the vaccine can be vaccinated for free. If you can, you can contact the relevant departments as soon as possible and queue up for vaccination, so that you and your family can work and live in peace of mind.

Although China's epidemic prevention and control is relatively stable, we should try to avoid going to crowded places. After all, there will be some special emergencies beyond our control.

Then have a good rest, improve immunity and make yourself healthier is the truth. As for those unrealistic designs and products, just look and listen.
