A member asked:

What would happen if your immune system didn't fight off the flu. would it spread to your whole body and kill u or would u just be chronically sick?

A doctor has provided 1 answer

It may kill you: Yes, it would spread primarily in your lungs, causing you to mount a high inflammatory response and flood your lungs with fluid. You could die and many people die of the flu every year. In fact, in 1918, before flu vaccines, more people died of the flu around the world than in all of wwi. So, yes, you would get very sick and could die.
