I've been immersed in work and family for a few days, so not sure if this has been discussed.
Back in mid December, one of my close friends came back from a year touring China. I went to his house, he came up and visited me and my family. Anyway, January sucked for us. My five year old son was out of school for two weeks with bronchitis that had him requiring his asthma meds around the clock. My seven year old daughter spent seven days out of school with a fever that meds could barely break. I got my ass kicked, spent weeks suffering exhaustion, a cough, sniffles, and my wife got hit too.
It's possible we had bad flu, but we don't usually get sick, and definitely not to the degree we all got it in January. I'm just pondering the possibility that my good buddy brought something unintended back with him.
If Italy believes it was around in Nov/Dec, I see no reason it couldn't have been here nearly as long..
