Yeah the health ramifications are massive. you may go under debt and probably accrue more of you default on a few payments but if you are sick and can’t get back up fast potentially your entirely family will suffer a lot
The bigger worry here is that the kids pass it to a parent since most cases in children are mild. A bad case of covid (not even talking about a fatal case) could have you out of commission unable to work for months. And then medical bills on top of that.
