I note here in Arizona really high numbers of flu cases for this early in the season. Don't know why. Most folks don't know about some of the influenza outbreaks of the early 1900s. The so-called Spanish Flu hit in 1911 and killed millions of people. San Francisco was especially hard hit. I've seen stacks of hastily built coffins that were piled high as no one had time to bury any of them because people were dying so fast. Flu is not as virulent now. And we have effective vaccines that weren't available back then. Official records say 556 people died in the US last year from the flu. I still get my flu shot.
