>The Flu has a mortality rate of 2 per 100k Nope, it doesn't. Mortality rate is not the same as annual deaths per capita. The number you quoted refers to the same context as traffic-related deaths per 100,000 population, which is 3.1 per 100,000 in the UK. This doesn't mean that if you are in traffic-related incident, you only have a 0.0031% of dying! Same with influenza - the mortality rate is 0.1%-0.15% (average season) up to 1.25%-5% (pandemic flu) [1]
