That's a fair comment. I used it as I wanted a noun short enough to fit in a list.

Maybe it's better to go even vaguer though: "food hygiene standards so low they keep causing pandemics".

Actually, wet markets in Asia have the same health standards like the ones in China: close to none ;).

Covid19 spread faster, unfortunately. There are quite a few viruses/infectious diseases spreading in Asia that didn't made it big-time like Covid19.
