‘Double-masking’ encouraged

"If you have a physical covering with one layer (and) you put another layer on, it just makes common sense that it likely would be more effective." - Dr Anthony Fauci

PETALING JAYA: Some countries are revising their face mask guidelines by recommending “double-masking” or only allowing medical masks, especially as new variants of the coronavirus emerge.

The US Centers for Disease Control and Prevention (CDC) recently updated its face mask guidance, which now encourages the wearing of a medical face mask with a fabric face mask layered on top of it.
