Mask wearing Cuts Covid-19 risk in half

An analysis of studies across the world revealed that wearing a Mask, hand-washing and social distancing are some of the most effective ways to prevent catching COVID-19 and spreading the disease. Global health care published a massive review Thursday that analyzed 72 studies worldwide to evaluate how non-pharmaceutical health measures reduced cases of COVID-19.

Researchers found measures like hand-washing, wearing Mask and physical distancing significantly reduced incidences of COVID-19.  Researchers supported vaccines and agreed they have proven to be safe and effective and can save lives. However, most vaccines do not give people 100% protection, and it’s not known how vaccines will prevent the future spread of COVID-19, given the growing trend of variants like a delta.

Researchers found that wearing a Mask could reduce COVID-19 incidence by 53%.

One experiment across 200 countries showed 45.7 percent fewer COVID-19 related deaths in countries where Mask-wearing was mandatory, according to the study. In the U.S., one study reported a 29 percent reduction in COVID-19 transmission in states where Mask-wearing was required.  Social distancing has also proven effective, with researchers finding that an analysis of five different studies indicated a 25 percent reduction in the incidence of COVID-19.
