Back in January my friends kid got really sick one night. I happened to be over visiting at the time and got sick later that night, it hit hard and fast but disappeared completely only to reappear a day later. I had a fever, chills, reduced sense of smell and taste, sore throat, raspy breathing and then it morphed into a cough that lasted over a month. My friends son was fine and running around the next day. Pretty sure it was Covid. All I know is it wasn't vaccine worthy and no worse than the regular flu.
