Studies as of now suggest that the virus can last for 3 days on a surface. So if you ship fly them over here from China, say a half a day flight, you have a good 2.5 days to potentially accidentally infect people.

Are you going to "cmmon man" me now?

1. Mask / test kit made in China.

2. Presumably, it came in contact with the hands of the people making it, in China.

3. If any of those people making the masks and test kits were infected, then there's a chance that the virus itself will be actually sitting on the masks and test kits themselves.

So, we just ignore that?
