When I was young, I had a high temperature fever up to 42゜C (about 107.6゜F), and it caused a hyperpyretic convulsion for about 1min. Is this high body tempertature caused by over activated cytokine or even a cytokine storm?
Probably not cytokine storm; you would have experienced more problems probably. Many infections can cause high fevers and could be caused by cytokines or toxins from the infection.
