Health Risks for Travelers

Locals might drink the tap water every day without a second thought, but for travelers, it’s a different story. Your body isn’t used to the bacteria or water treatment systems, which can lead to a not-so-fun experience.

What you could be dealing with:

  • E. coli and other bacteria causing traveler’s diarrhea
  • Parasites like Giardia from untreated or poorly filtered water
  • Hepatitis A or norovirus picked up in areas with poor sanitation
  • Even heavy metals if the pipes are outdated or the source is unregulated

Problem spots include:

  • Remote villages and rural zones
  • Places where floods disrupt the water supply
  • Older hotels or buildings using rooftop tanks or old plumbing

Bottom line: clean-looking water isn’t always clean. When you’re abroad, it’s smart to stay alert to water quality and protect yourself from getting sick.

If you experience persistent symptoms while traveling in Saint Martin, consult a local doctor or pharmacist. In many tourist areas, English-speaking care is available.
