Scientists reveal the best and worst face masks to use for COVID-19 protection
The coronavirus pandemic is far from over, as the number of reported infections tops 20 million globally. The coronavirus disease (COVID-19), which has emerged in December 2019 in China, has now spread across 188 countries and territories, taking more than 733,000 lives. Since the advent of the pandemic, health experts have recommended wearing face masks to reduce the risk of infection.
Caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), COVID-19 disease can spread through respiratory droplets when a person coughs, sneezes, or talks. However, using face masks can significantly reduce the risk of SARS-CoV-2 virus transmission. As the pandemic grew, the supply of surgical and medical masks was markedly depleted. Subsequently, health organizations recommended using handmade masks.
With that in mind, scientists at Duke University went about testing 14 different types of masks to determine which offers the best protection against SARS-CoV-2 infection. The team has found that bandannas, gaiters, and knitted masks are some of the least effective face coverings for preventing the spread of SARS-CoV-2.
