One thing that has come out of the news about the Corona Virus is that the bulk of the pharmaceuticals used in the US are manufactured in China, or use Chinese components. This leaves the US population vulnerable to long term damage to their health. This may have already happened, as I understand that over 70% of the US population is unsuitable for military service due to health problems. This seems to be tolerated, and even encouraged. On the other hand the possible use of 5G equipment manufactured in China has created massive disruption to trade. This is despite the fact that Chinese microprocessors are being used in advanced military equipment such as fighter jets.
I haven't heard that there are any official incidents in the US.
The virus is not spread but he microprocessors or the medicines that come from China. The virus is spread when people are getting in touch so I don't think that your concern is valid.
