Question: What is the most deadliest disease ?

Nicola Wardrop answered on 15 Mar 2013:

Well, there are lots of deadly ones, and it depends on exactly what you mean by deadly. You get some which kill almost all the people that catch them, like ebola, which makes you bleed from your eyes, your gums, and your bum. On the other hand, the, eboloa is very rare, so it doesn’t kill a big number of people each year. Then you get some diseases which only kills some of the people that get the disease (like diarrhoea, or flu), but they are much more common…so because many many more people catch them, it also means more people will die of the disease, so perhaps that makes it deadlier?
