I've already been preparing as a hobby for the last 3 years, not specifically for coronavirus, but here's how I'm prepared for it:
- I work remotely, so I can hunker down at home and have my income totally unaffected.
- I've close to 6 months worth of food, and I've been buying more in the last month as the news continues. I can give some tips on what I think is good inexpensive food to get in case anyone is interested.
- I'm fasting regularly, which will realistically extend my food supply. Most people calculate their food supply by 3 meals a day plus snacks, but you can go days without eating. Right now I'm closing in on 72 hours without food. I'm perfectly fine. You get used to it. The key is getting your electrolytes and getting out of your sugar addiction.
- I have lots of water stored up, although that's not going to be much of a problem with COVID-19. Several filters meant to remove viruses, though I have a distiller so I would probably just use that if I was really that paranoid about my water, which I probably won't be.
- My medicine cabinet has everything you can think of and more. I have 2 first aid kits and a trauma kit. I have what it takes to turn the entrance to my home into a decon chamber, if need be. I have tons of bleach and disinfectants.
- I have full gas masks with filters, including adapters for 3M filters, which should be perfectly sufficient to remove droplets in the air. I also have full tyvek suits in case there's a worst case scenario but I have to leave my home. I have lots of N95 masks, but obviously you can't count on those for very much. I certainly don't have the belief that even the gas masks will prevent anything. It's just hedging my bets.

All that said, I am not paranoid. I don't even have anxiety over it. Those things I mentioned would only come into play if things went extremely bad. My life wouldn't be very different if I had to stay indoors for months on end, so long as utilities continue to operate. Even if the supply chain broke down, I would probably be better off staying indoors than trying to bug out to somewhere else.
One other thing I'm doing is trying to sell off a high value items I've been holding on to, but I'm selling them off now because the money could save me from strife if there's widespread infection and my job totally falls apart.
