Are you talking about the Covid-19? If so, hopefully this will calm you down. 80% are mild, tons are non-symptomatic, only 2% chance of death, and depending your parents ages' the likelihood is possibly reduced. You're in what, your 20's or 30's? the chance of you getting infected is so very low presuming you follow proper protocol, even negligible. Only people are at a much higher rate, but you specifically mentioned you infecting them because you work in healthcare, which presuming you're relatively young, will likely not be the case. After all of the statistic crunching, assuming 50% of americans are infected, that is only 1% of the entire US dead. A lot compared to cancer, but not apocalypse worthy by any means. nor anything to be paranoid about. Good luck.
