So is there a risk from items shipped from China to the US?
Yes. However, it depends on how many days it takes between being off loaded in the US and it gets to your front porch.
However, not much is being shipped these days and if it is countries aren’t accepting the cargo or even allowing the ships to dock. Of course, the US is allowing cargo planes to fly back and forth stopping in Alaska to refuel.
Many factories in China were shut down until the government decided that wouldn’t be good for the market (always the market these days and not the people) so are opening back up. Basically, if you can walk you will return to work until you fall on the floor and they drag you away and replace you with the next walking dead.
