Bali belly is a common term for traveler’s diarrhea, often affecting visitors to Bali and other parts of Southeast Asia. 

It’s usually caused by bacteria, viruses, or parasites from contaminated food or water. But one common question travelers ask is: Is Bali belly contagious?

The answer is yes, in some cases.

How Bali Belly Spreads

Bali belly can be contagious if it’s caused by certain viruses (like norovirus) or bacteria (E. coli, Salmonella, Shigella) that pass from person to person. 

These germs spread through the fecal-oral route, meaning you can catch it by:

• Eating food prepared by someone who hasn’t washed their hands properly
• Drinking contaminated water or beverages with unsafe ice
• Touching contaminated surfaces and then touching your mouth
• Sharing utensils or close contact with an infected person

Parasite-related Bali belly, such as giardiasis, can also be passed on through poor hygiene or contaminated water.

How to Prevent Spreading Bali Belly

If you have Bali belly, follow these steps to reduce the risk of passing it to others:

• Wash your hands thoroughly with soap and water, especially after using the toilet.
• Avoid preparing food for others until you’re fully recovered.
• Use bottled or boiled water for drinking and brushing teeth.
• Don’t share utensils, drinks, or towels.

When to Seek Medical Help

See a doctor if you have diarrhea lasting more than 5 days, severe dehydration, high fever, or blood in your stool. 

Bali belly can be contagious, depending on the cause. Practicing good hygiene is key to protecting yourself and others.
