Mask-wearing cuts new COVID-19 cases by 53%, global studies suggest
published Thursday in the "British Medical Journal," focused on studies related to pandemic precautions, such as handwashing, mask-wearing and physical distancing. Such public health measures are known to be beneficial in fighting respiratory infections — including influenza. But a lack of good research in this space "is a pandemic tragedy," researchers argued in a linked editorial. The team noted that just 4% of global research funding for COVID-19 has been put toward public health measures.Nearly all the studies analyzed by the team were observational and carried out in Asia, the U.S., Europe, the Middle East, Africa, South America and Australia.
