The majority of human infections are caused by direct or indirect contact with the blood or organs of infected animals.

Crimean-Congo haemorrhagic fever (CCHF) is primarily spread to humans either by infected ticks or animal blood. Human-to-human transmission can also occur resulting from close contact with the blood, organs or other bodily fluids of an infected person.

West Nile virus (WNV) is spread by mosquitoes in many countries. There are usually no symptoms, although some people develop mild flu-like symptoms, nausea and skin rash. The virus is not contagious and should get better without any treatment.

Avoid swimming in fresh water rivers, streams and lakes if you can.

Schistosomiasis can usually be treated successfully with a short course of a medication that kills the worms.
