Health Risks for Travelers
Even if the tap water is safe for residents, foreign travelers often face higher health risks due to exposure to unfamiliar organisms and differing hygiene standards.
You may be exposed to:
- Bacteria like E. coli, causing traveler’s diarrhea
- Parasites such as Giardia or Cryptosporidium, from untreated or contaminated water sources
- Viruses like norovirus and hepatitis A, spread through unclean water systems
- In some countries, chemical toxins from old pipes or agricultural runoff
Contamination is most common in:
- Regions without consistent municipal treatment
- Areas impacted by seasonal flooding or unreliable sanitation
- Buildings with aging infrastructure or poorly maintained tanks
Remember: clear water isn’t always safe water. Invisible contaminants can still cause serious issues, from mild digestive discomfort to prolonged illness.
If you experience persistent symptoms while traveling in Mayotte, consult a local doctor or pharmacist. In many tourist areas, English-speaking care is available.
