Don't freak out, Good Whiskey. I have nearly 50 trips around the sun and lived a pretty action packed life for most of them and I can tell you with iron clad certainty that there is no situation that panic helps you deal with. Just take a long, slow breath and then gather as many facts as you can. If you can't get hand sanitizer grab a few cases of bottled water, flats of canned food to keep you in grub for a couple weeks and then just chill out. Limit exposure to people, like vacations, wash your hands often and avoid touching your face.
Everyone is experiencing different levels of concern, but that's because almost none of us have ever seen anything quite like this in our lives and it's perfectly human to fear the unknown, but just remember; it's natural to experience fear, but one of the big reasons we stand at the top of the food chain as the dominant species and stewards of the planet is because of our ability to master our fear and to act constructively despite it.
Edit: almost forgot: Pornhub has a pretty decent plan to help curb un-necessary contact with other people. I hear.
