Yes, that is exactly why everyone is in lockdown, because there is enough panic and nothing more can be done. So anything that seems politically acceptable is being done. It won't be effective and is at best false sense of security. It is about as effective as quarantining kids after mumps outbreaks, which is not much, and this thing spreads quicker. The question is not if, but when you will be infected, and if your immune system will be able to handle it. For most, it will be a cold, for the others where it won't, unless they have their own hardware, they're screwed. As seen in Italy. Chinese were able to spin up hospitals, most everyone else does not have enough hardware.

Hospitals get overloaded with about few hundred cases, give or take.

Coronavirus tests are not effective preventative measures. (Not yet anyway.)

Good pulse oximeter costs maybe $20, an O2 tank with hardware and mask $80-100. If you cannot afford that, you're literally screwed. I bet you would pay more off a copay for a bed in the US. If that's the case, good luck.

If you cannot afford food, you're also screwed, there's no charity that will help. As a reminder, many people died from Spanish Flu due to malnutrition. And old age. This combination is also problematic for COVID-19. Strict isolation measures do not work reliably against this kind of virus. They did not work for flu nor for cold, they won't for this one. They can at best slow it down a bit and delay, which is ok if you use this time to do something meaningful - China did, others cannot.

Government could try to help with this but US is allergic to handouts. There is enough food and production capability to distribute rations if need be. I hope they're being stockpiled. Probably are not.
