The details of the 1918 morbidity and mortality remain quite controversial, it must be said. Cytokine storms are currently fashionable, but CNS tropism was all the rage at one time.
Is the cytokine storm theory part of the "it was really secondary infections" story?
As I understand it, it's more of an over-reaction of the immune response, triggered by an "anitgenic shift" in the envelope proteins of influenza (hemagglutinin and neuarmindase). The major flu pandemics all involve a novel strain of influenza A such as the H1N1 variant we're now seeing. It's actually a lot like septic shock in bacterial infections.
