Covid-19..I’m confused

Maybe I am totally missing something or just flat out stupid. This is a big deal 100%. I am taking it seriously and staying home. I am pregnant and worried. There is so much panic and uncertainty. It’s a scary time right now..

Maybe someone can better explain this (hopefully without being rude) since I’m truly not understanding, why is everyone acting like it’s literally the absolute end of the world and that there is no coming back from this? Why does everyone think this is going to go on for so long and then the worlds going to end? I must be missing something.
