1. Threat: Dengue Fever

Danger zones: Tropical and subtropical regions

What it is: Bowel woes brought on by contaminated food or water.

Danger zones: Pretty much anywhere; diarrhoea strikes as many as half of international travellers, according to the US Centre for Disease Control.

Prevent it: Steer clear of tap water, ice, undercooked meat, salads and unpeeled raw vegetables and fruit. Just in case, pack an OTC diarrhoea remedy, such as Imodium A-D (loperamide), to treat the trots.

3. Threat: Bilharzia

What it is: A parasitic disease from freshwater worms that enter your body and produce eggs, which travel to your internal organs.

Danger zones: Your risk is highest in southern and sub-Saharan Africa, but you’re also exposed in areas of the Middle East, Asia, and South America.

Prevent it: Don’t drink from or wade, swim or bathe in bodies of freshwater, such as rivers, lakes and streams.
