I am confident in our medical system. Both our food supply and medical system are more hygienic than China, which is going to help a lot. If we can keep this to a small number of cases, I don't think we will see as many deaths as in China. We can give them excellent care. However, if we don't contain it, and overload our medical system, then the death rates will be about the same as China's.
I am not an extreme prepper, but I have been building up my pantry starting last fall, but more so in the last few weeks. I can ride out the virus at home, and can even work from home. People don't need to go full out zombie prepping. The electricity will stay on, we can cook in our kitchens, etc.
If anyone is stocking up preparing for this, don't forget to not only get food, but to get books or a project around the house you can do while this blows over. If we are trapped in our homes for a while, we might as well do something productive to pass the time.
Our hospitals are nearly overwhelmed at times now with the flu strains going around. Hopefully, the Trump Administration and the states will be successful enough with containment to hold the geographical progress of the virus back long enough for it to mutates towards weakness. Warmer, more humid weather ahead is very important.
Strangely, coronaviruses tend to die much quicker in more humid and warmer conditions (especially more humid). Think about surfaces. The eastern half of our country is far more densely populated and busy.
