"Besides replicating very quickly, the 1918 strain seems to trigger a particularly intense response from the immune system, including a ‘cytokine storm’ – the rapid release of immune cells and inflammatory molecules.
Although a robust immune response should help us fight infection, an over-reaction of this kind can overload the body, leading to severe inflammation and a build-up of fluid in the lungs that could increase the chance of secondary infections.
The cytokine storm might help to explain why young, healthy adults – who normally find it easier to shake off flu – were the worst affected, since in this case their stronger immune systems created an even more severe cytokine storm."

"A new, invisible and at times virtual, tyranny is established, one which unilaterally and irremediably imposes its own laws and rules. Moreover, indebtedness and credit distance countries from their real economy and citizens from their real buying power. Added to this, as if it were needed, is widespread corruption and selfish fiscal evasion which have taken on worldwide dimensions. The will to power and of possession has become limitless." Francis I, 16 May 2013
