Not surprised to read about your first exposure, I've personally always believed that I had contracted it sometime during the Christmas week in the winter before the official declaration occurred. Problem for me was that it could have been masked by the Cold induced Bronchitis that I had to deal with for most of the winter as well. All i know is that, with each declared "official" outbreak of yet another variant, I become more and more of an hermit. Fortunately my job/employers actually encourage me to stay away from people and I embrace that philosophy whole- heartedly.
