50 million dead. 500 million infected. And a large percentage of fatalities were people from 20-40 years old who died of cytokine storms, an internal chemical death caused by their robust immune systems. Even today with state-of-the-art treatment, the mortality rate of cytokine storm is 27%. These infections can happen again.
