Here's a piece of possibly optimistic news: of the 241 reported cases CDC is currently investigating, 121 are pending, 114 were NEGATIVE for 2019-nCoV, and only six were positive. They're in California, Arizona, Illinois, and Washington State. There's a reasonable chance that some of those cases are more run of the mill influenza. And while the 2-3% fatality rate they're seeing in China is troubling, it certainly isn't the 10%, 15%, and 20% rates that some of the worst epidemics have produced.
What can anyone say? Hand washing, hand washing, hand washing, use hand sanitizer by the bucket, and don't share utensils, cups, etc. And good luck.
