Same! In mid-February I went to a party. A couple of my friends were getting over "a really weird cold" that "everyone in the office had". A few days later, I was sick with the same symptoms, mostly a dry cough. I thought nothing of it except that it was very unusual for the kinds of colds that I usually get (I am a sore throat and aches guy, so I was thrown off by not aching and having a cough). I had this for a couple weeks.
I wasn't working at the time, but it was minor enough that I would have gone to work. That is also very rare for me, usually I am out of commission for a week when I get a cold.
Was it Coronavirus? I have no way of knowing. But looking back, it seems very suspicious. An extra-infectious cold with the same symptoms of Coronavirus going around the New York office populated by people that travel internationally extensively? You have to wonder.
I kind of assume that Coronavirus cases are massively underreported. Given that 20% of cases are people without symptoms, what would prompt them to get tested? And all the advice I've read is along the lines of "if you think you have it, don't get tested, just stay home and get over it". With that advice, I have to assume that many cases are not accounted for in the official data. It does seem strange to me that if Coronavirus was circulating in New York in mid-February that it didn't show up at all until early March "officially", though. It's unlikely that not one person would have severe symptoms. For that reason, I assume I'm not immune and am self-isolating like everyone else... but if I can get an antibody test, I would love one. I am very curious as to what happened there.
