External concerts, for example, often involve crowded people for several hours and are at high risk, Popescu said. “Fresh air is essential and the air is fresh, but it only helps when you are shoulder to shoulder with hundreds of people for hours, screaming and shouting,” he says.
But I’m Healthy and Dangerous
Apart from the advice above, there are two things to consider when choosing to wear a mask: to protect yourself and others. Unless you are away from everyone and have a bad Covid test in the morning, you have to assume that you always have a chance of getting the virus, which is why you can infect others.
If you are among people who are at high risk of contracting a serious illness or disease – such as people with immunodeficiency, vaccinated children, the elderly, or someone who is at high risk – it is best to wear a face mask to protect you. In places like shopping malls and shopping malls, where almost everyone has to go even if they are in a dangerous group, the best thing to do is always wear a mask, regardless of the amount of HIV infection, because you never know you will be around unsafe people.
In places like restaurants, bars, and house meetings where you don’t have to wear a mask, your choice depends on you the level of risk tolerance. How comfortable do you feel about not wearing a mask?
“There are ways to get rid of Covid, and then there are things that can make people worse,” he says Anthony Harris, a pathologist at the University of Maryland School of Medicine. “If you combine these two roles with the mindset of the most vulnerable, that’s how they should make decisions. There is no black or white.”
Apart from the prevalence of local diseases, there are a number of factors to consider:
- What are your chances of getting an infectious disease? If you are in their 70s or 70s or are not protected by the immune system, you can still get an infectious disease even if it does not kill you.
- Are there others who are vaccinated or who have not been vaccinated? (If you do not know, assume that some do not have the vaccine.)
- Do you love others?
- How long do you live or how long do you live near others?
- How big is the place?
- How fresh is the air?
Best Mask Stories
Also keep in mind that not all masks are made the same.
“I encourage people to use a high-quality mask, which is appropriate and filtered,” says Popscu. “Making sure the masks are the best is the most important thing in the house.”
Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, has recommended for months that Americans wear good security than cloth masks, whose form and function vary greatly. In the first half of 2020, health experts he thwarted the common people since wearing N95, KN95, and similar breathing masks so that health workers had enough. But now, Osterholm says, health workers and other services that require respiration have more to offer. There is no reason why ordinary people should not wear this often very useful masks too. If nothing else, get a mask and medical supplies.
Air, Air, Air
Of the above, the latter is one of the most important, he says Alex Huffman, an astronomer studying bioaerosols at the University of Denver. The reason “outdoors is much safer than indoors” is that the germs we emit and others do not have a chance to thrive. They just float and go. In the house is another matter.
The viral infections that a person with the virus emits are “mixed in a room and can be trapped in machines if there is enough air,” says Huffman. In a stable room with aerosols, it takes a small amount of oxygen to breathe through the virus. The problem with the rooms is also important, he says.
