Are two face masks better than one for COVID-19 protection?

The need for double masking to stop the spread of COVID-19 infections in the community is a much talked about subject.

Recently, based on empirical studies conducted, the Centre for Disease Control (CDC) said it was not just a single mask, but wearing a tight-fitting mask or a double mask that could ward off the COVID-19 virus with a success rate of 95 per cent.

In a simulated breathing experiment, it was seen that while the surgical three-ply mask could block infection transmission by 42 per cent, wearing a cloth mask above that could provide an additional 44 per cent block to any virus.
