Thursday, April 15, 2021 (HealthDay News)-A new study found that countries that required people to wear masks last year had a lower incidence of COVID-19 than countries without masks.

Researchers examined data from all 50 states and Washington, DC, to evaluate mask policies, people’s self-reported mask use in public, and COVID rates from May 2020 to October 2020.

They delayed one month between wearing a mask and the subsequent potential impact on the COVID infection rate.

The Boston University team recently wrote on the preprint server: “States with the lowest compliance with masks are most likely to have higher COVID-19 rates in the following months, regardless of mask policy or demographic factors. .” MedRxiv, Before peer review of their findings.

Charlie Fischer of the Boston University School of Public Health led the study.The results of the final review will be published in the April 14th journal One number pass.

The study listed the incidence of COVID as the highest 200 cases per 100,000 residents. Researchers report that 14 of the 15 states that do not require people to wear masks in public places are in this category.

They found that none of the eight states with a self-reported public mask usage rate of 75% or higher had a high COVID rate.

In the next month, the average infection rate in these eight states was 109.26 per 100,000 inhabitants, while the use of public masks in the states with less than 75% was 249.99 per 100,000 inhabitants.

“The protective effect of wearing a mask is obvious in the four months of the entire treatment process. Pandemic, Even after adjusting the masking policy, distance policy and the correlation of demographic factors,” Fischer and her colleagues said in a press release.

Countries have different policies on the use of masks, and the author said that understanding the link between mask use and COVID rates can help guide policies to reduce the pandemic-related health care system pressure, economic instability, and deaths.

They suggested that policies and public health efforts to reduce the spread of COVID should include increasing the use of masks nationwide.
