Welp, I just rapid-tested positive for COVID-19. I had an exposure notification from the #UbuntuSummit in Prague, but masked for the entire flights and as often as was practical at the summit between eating and drinking. It turns out, there was a lot of eating and drinking.
I'm vaccinated and so far the only symptom has been a drippy nose and maybe some fatigue I chalked up to jetlag, but I'm grumpy. And now I've exposed my family.
Maybe attending an in-person summit was a dumb idea after all.
