I was looking up "coronavirus" on google trends. What I saw was a flat 0 except for a blip in late august, and a score of 100 on September 21, 2019 coming from Hubei Province specifically.

Those results remained the same for over a month until I posted the above in a hacker news comment. Then I was down voted heavily and the results suddenly changed. I do have a picture of it, because I wanted to share the results with my friend and they dont use social media, so I forwarded a picture.

while I agree with the hacker news downvoters (the downvote, hate, hate, unsubscribe, rage, rage, you must be stupid crowd) that this doesn't prove anything, it is certainly part of the evidence building up.
