We commonly assume that the deadliest or the most dangerous diseases in the world are necessarily grimy, malevolent, and horrific. While some parts of it are right, most of the diseases with the highest fatality rates in the world are slow, omnipresent, and anyone can be susceptible to them. In fact, according to the World Health Organisation, a jarring 68% deaths in the year 2015 were caused by slow progressing diseases, some of which are even partially preventable.

Here are 9 of the world’s most dangerous diseases, with the highest fatality rates:
