Sepsis - the body attacking organs due to an excessive immune response, is one of the main reasons of death in influenza.
The damage from kidneys and other organs is likely tissue damage from sepsis. It's common for those with severe influenza responses to also die from cardiac issues.
Maybe someone can help me out here, at what point in our history did the mainstream media become dishonest wh0res? Almost everything they write is inaccurate and editorialized.
