Instead of killing mostly infants and elderly, it had little effect on them and killed mostly young adults. A group rarely significantly affected by flu. It also caused significant neurological problems in some survivors, which is also rare for flu.

∙ 13y agoIt is believed to have been what is called a cytokine storm. Young healthy adults were getting the flu most and became worse quickly, especially among the enlisted men in WW1, that was occurring at the same time (and this helped spread the flu world wide as soldiers came and went from different theaters of war). It was because they were young and healthy that they had the cytokine storm, which is a tremendous over-reaction from the immune system to an invading infectious agent. In this problem, your body is trying to wash the disease from your lungs and the lungs fill up with fluids and dead cells and that causes more cytokine release and it continues as repeated chain reaction. In the process, that interferes with respiratory function and system failure that causes other organs to fail. It can cause death from pneumonia and respiratory failure caused by their own body's over reaction. Millions of people died in the pandemic (it was world wide, not just epidemics).
