Signature of COVID-19

Without COVID -19 pandemic, one will never see people hanging out surgical masks or N95 face mask in the balcony to be re-cycled.

The pandemic has depleted the supply of face masks for public consumption worldwide. With situation being under control in China, the supply of face masks has improved over the the weeks.

Of course it is generally not advisable to re-cycle face masks. But when the supply is low, one has to improvise to the best of our ability.
