I was unlucky to change 5 countries since the start of the epidemic. And I wore masks and gloves on each flight. Individual masks I had from my life in China. And I’m glad that after 7 different airports, and close contact (positive cases from my flights) with the disease, I’m still healthy.
I’m not sure about the science behind masks, but I’m safe, and in isolation (for the 3rd time now.) Health officials need masks more than we do, that is a fact.
But you can make one yourself, or support online artists and tailors that are producing them now.
I wore PM2.5 cloth masks. PM2.5 are reusable (you can wash them), and hopefully they worked. But maybe I was just lucky. Who knows.
Anyway, stay safe everyone!
