      Hello.

      Lots and lots and lots. I’m not an expert on this topic, but I don’t think there is actually a precise answer, as we’re always discovering new types of disease and disorder.

      Have a look at the World Health Organisation website to see the most common. Diseases that affect the cardiovascular system (heart, blood vessels and blood) are the most common worldwide.

      Try Googling tropical diseases if you want to see some interesting ones 🙂
