Okay, so it's not really plague, which is caused by a bacterium called Yersinia Pestis and spread by fleas on rats. Instead this is a Coronavirus that produces a disease called COVID-19, and is spread primarily by close contact with an infected person. It's reportedly spreading faster than the flu viruses, and appears to have x10 the fatality rate of flu.
I've been busy with other activities and haven't been getting to my ballet classes with any regularity recently. The ballet schools had been attempting to maintain their schedules, but with the federal and state health departments raising alarms, one by one they've all decided to close for several weeks. This makes sense to me -- I'm pretty sure the last time I got sick it was something I was exposed to at the ballet school.
Thus far I'm healthy and hope to stay that way. We'll see how this plays out; there's not much more I can do.
