Wearing face masks made little or no difference in preventing spread of COVID-19: Study

New Delhi: It has been more than three years since the coronavirus and its disease COVID-19 spread, and the disease has claimed millions of lives worldwide, but so far there is not enough evidence that wearing a face mask can prevent the spread of the disease.

The Centers for Disease Control and Prevention (CDC) initially claimed that face masks were not necessary, but by April 2020, they started asking people to wear masks.

CDC Director Dr. Robert Redfield said in September that face masks are the most powerful health weapon available for people. Then soon wearing face masks was made mandatory worldwide.

Now, a review led by 12 researchers from leading universities around the world has said that the role of wearing masks in preventing the spread of Covid-19 may have been minor or not at all.
