re: If new technology in contact tracing showed exactly whom you caught the common cold from..

Pretty easily actually. We know that you bought some cold medicine on Amazon using Google pay on Tuesday, and exposure on Thursday, so you knew you were at ill.

We can also see your search history about cold symptoms. Your phone shows us an elevated baseline heart rate which is consistent with a fever.

Just like a drunk driver who got behind the wheel knowing that they were intoxicated.


All the metrics to determine if you're sick or not are already in place, We just need the contract tracing to prove who you gave it to.

Now technically they could have gotten sick from somebody else even though contract tracing shows you were next to them while you were sick, so we still need developments in virus mutation with genetic markers to prove that you got that person sick
