It's called a cytokine storm.
It's a potentially fatal immune reaction consisting of a positive feedback loop between cytokines and immune cells, with highly elevated levels of various cytokines.
When the immune system is fighting pathogens, cytokines signal immune cells such as T-cells and macrophages to travel to the site of infection. In addition, cytokines activate those cells, stimulating them to produce more cytokines. Normally, this feedback loop is kept in check by the body. However, in some instances, the reaction becomes uncontrolled, and too many immune cells are activated in a single place.
Gnereally a stronger immune system will overreact and too many cells will be activated.
This can be fatal.
Spanish flu in 1918 was most deadly in people aged 20-40 because of this.
You just read that in Wikipedia didn't you ?
I'll believe what the bio-chemist told me and not some newspaper charlie.
