At the start of January I was super ill for about two days with what I thought was a bad bout of flu, and had a persistent cough for several weeks afterwards. I had just visited family for the holidays and it happened right after I had left. My dad was also similarly ill at the same time, and his wife had experienced a similarly rough time a couple weeks prior, so we've been operating under the possibility that we all had covid and was unaware it wasn't the flu.
