Here in Louisiana, We had to cancel Christmas parties because everyone was so sick with flu-like symptoms. Who knows?
That's why I wonder. The CDC makes it sounds like it was late in January 2020, but from many indications, it might have been in December. Our kid knew someone from work who was seriously ill (looking back, all of his symptoms were classic COVID-19, especially the difficulty breathing part). He had traveled from the western part of the US to Texas several days before Christmas. Based on the CDC's timeline, that would have been too early.
Move to a location west of the Pecos above 4000 ft. It might help. Nothing better than cool dry air without mosquitoes.
