But here's a flip side to this. What is the antiviral medication works better the sooner you start it

What if you don't goto hospital and then end up not getting any antiviral meds and instead end up dead.

Also, it's hard to know just how sick you are. When I was sick with a viral infection my red blood cells were not carrying enough oxygen and I just figured not being able to breath was just a normal part of being sick.
