No doubt and I believe the virus was in other parts of the world long before February. I had an unexplained flu-like illness in January and was tested for Influenza A and B, both of which were negative. I have a fever, shortness of breath, aches, and generally felt like absolute crap. I got better, and 3-4 weeks later I came down with similar symptoms again and went to get tested. This time around I tested positive for Influenza A since my son and wife had had the week before (thanks daycare). It's unlikely that you'd get Influenza back to back like that, even between A and B (it's possible though and the flu test is only about 80% accurate). I'm not saying I have COVID-19, but I do go back and think about it anytime something comes out talking about the potential of COVID-19 being in the population earlier than expected.
Another thing that sort of makes me think too is that in January we had a huge convention in Salt Lake for one of those multilevel marketing pyramid schemes that seem to be popular in China. As a result, we had a sizeable group of Chinese convention-goers in town for about a week. Since the convention center is next to my office, the convention-goers used the restaurants, grocery store, and other commercial spaces (like the mall) around the area too. I visited those places pretty much every day that week too since I needed lunch or to run errands. When I went to urgent care when I felt sick the first time, the doctor I saw said they'd see an influx of people with the same symptoms around that time as well, but wrote it off as either "just some bug" or "the flu" without testing.
Like I said, I'm not saying this means I had COVID-19, but it really makes me think when I start putting pieces together.
I also wonder about EVALI (the disease associated with vaping). Many e-liquids are made in China or used ingredients from a chemical factory there. We started seeing this mysterious illness last year and I believe it's still not really explained all that well. While the connection is shakey, it does stand out in my mind.
