An epidemiologist I know recommended reading up on the 1918 epidemic. While it is a lesson in underreaction, it’s also a lesson in overreaction. Egypt is killing pigs to stop it. In discussing whether it’s better to overreact or underreact, or react just perfectly, please be informed. Wingnuts who say there’s no such thing as overreaction are overreacting.
Update: A friend of a friend is quarantined with this flu and is expected to make a full recovery soon. It seems a bullet was dodged as it was pure happenstance that my immediate friend hadn’t seen the former in a couple weeks.
