Then, some folks began doing something most of us hadn’t seen before: wearing surgical masks. Be taught more about whether or not facemasks can really stop spread of the flu, and which masks are the most effective.
Studies Show Masks Do Help
For many years, scientists weren’t positive if wearing a mask was efficient at stopping the spread of viruses. Nevertheless, latest research counsel that they will help.
First, a 2008 study published in the International Journal of Infectious Diseases concluded that when used accurately, masks are highly efficient in preventing the spread of viral infections. Family members of children with flu-like diseases who used the masks properly were eighty p.c less likely to be recognized with the illness. Surprisingly, the distinction between types of masks used was insignificant.

The results showed that those that wore masks in residence halls and practiced good handwashing reduced their risk of flu-like sickness by an astonishing seventy five percent.
Facemasks

Facemasks additionally protect towards splashes and sprays from others, corresponding to these from sneezes and coughs. The downside is that these masks don’t forestall the inhalation of small, airborne contaminants.
Respirators
Respirators, also called N95 respirator masks, are designed to protect the wearer from small particles within the air which will comprise viruses. They are certified by the CDC and the National Institute for Occupational Safety and Health. The name comes from the truth that they’ll filter 95 percent of airborne particles, according to the CDCTrusted Source.
