Australian hospital workers on the coronavirus front line say they daily receive letters of thanks, some people even bring them pizzas, but what they really need is proper respiratory face masks to replace faulty and homemade face shields.

While doctors and nurses in some hospitals struggle to obtain respiratory N95 face masks, Australians walking the streets can be seen wearing them.

"Every day we get a lot of thank you letters, some people bring pizza for us etc," one senior emergency doctor told Reuters. "But I just want to go there and say 'Hey, we're not hungry. We need masks'".
