When people from high-risk countries that have been
hit by more than
one wave of Covid-19 are so paranoid or petrified that they would wear more than
one face mask each time—for instance, two masks for a second wave, and three for a third wave.

19 second wave hits Singapore, third wave sweeps Delhi, and fourth wave grips Hong Kong, first-
world countries are worried that their local supply of masks might be hijacked by a
mask wave, as some extreme citizens take extra-precautionary measures to avoid getting infected.
