While some states hold issuanceMask mandates-And hardly affected cities take things between their own hands withFacial mask laws From their own doctors and scientists agree that face coatings are one of the most valuable tools to prevent the spread of coronavirus. In reality,Masks could be more effective that we realized, which is essential information in the middle ofCOVID SPIKES Across the country. But all masks are not created equal and, while something is usually better than nothing, new research reveals thatUsing scarves or cotton shirts as a facial coating is only slightly more effective than not to wear any mask at all.

A recent study by the University of Arizona, published in theJournal of Hospital Infection, evaluated theAbility of different mask materials to protect their bearers from the infection in a virus environment. They discovered that scarves, as well as cotton t-shirts, a reduction in the risk of infection of only 44% after 30 seconds and 24% after 20 minutes. Therefore, they concluded that these types of face cover are just "slightly better than not to wear any mask at all".

"We knew that the masks work", principal authorAmanda Wilson, a doctoral candidate in environmental health sciences in the Community, Environment and Policy Department, said in a statement. "But we wanted to know how well and compare different material effects on health outcomes."

While scarves and shirts have had weak brands, the researchers discovered that N99 masks were unsurprisingly the best option to prevent infection, N95 masks and surgical masks close behind. However, these masks are difficult to find, and because they are necessary for personal protective equipment (EPP) for medical workers, there is a debate on whether average citizens should have access to their access .

If you are looking for another strong option, your next best bet is something you've probably at home - a vacuum filter, which can be adapted to thepocket of a fabric mask. Wilson and his team discovered that vacuum filters reduce the risk of infection of 83% after 30 seconds of exposure and 58% after 20 minutes.

"We focus on masks protecting the wearer, but they are more important to protect others around you if you are infected," Wilson noted. "If you put fewer viruses in the air, you create a less contaminated environment around you. As our model shows, the amount of infectious virus you are exposed to a significant impact on your risk of infection and the potential of Other "masks to protect them too." And for more information on face coatings, you should wear,This is why facial masks are actually worse than the shields of the face, the doctor says.
