Infectious Disease & Hygiene Guide for Travel to the Netherlands
The Netherlands, located in Western Europe, is an advanced country with excellent sanitary conditions, but travelers should be aware of certain infectious diseases and food/water safety considerations. This article provides practical guidance on preventive measures and medication preparation from a pharmacist's perspective.
Basic Sanitary Conditions in the Netherlands
The Netherlands maintains high medical standards with strict drinking water quality regulations. In general, sanitary management is equivalent to that in Japan. However, travelers should pay attention to the following points.
Pharmacist's note Health insurance is mandatory under the Dutch healthcare system. We strongly recommend purchasing travel insurance before departure. Prescription medications require a physician's consultation in the Netherlands; Japanese prescriptions cannot be used.
Major Infectious Diseases of Concern
1. Influenza (Seasonal Flu)
Influenza season in the Netherlands runs from November to March. If your travel dates coincide with this period, take the following measures.
Prevention strategies
- Influenza vaccination before departure (October–November is optimal)
- Frequent handwashing and gargling during travel
- Mask-wearing in crowded places
Treatment medications
- Oseltamivir (Tamiflu): prescription medication
- Zanamivir (Relenza): inhalation medication
Pharmacist's note If you suspect influenza in the Netherlands, see a GP (General Practitioner) before antiviral medications are prescribed. Treatment is most effective when started within 48 hours of symptom onset.
2. COVID-19
As of 2024, COVID-19 transmission has subsided in the Netherlands, but seasonal outbreaks remain possible.
Prevention strategies
- Confirm vaccination status before departure
- Consider additional boosters if needed (especially for older adults and those with underlying conditions)
- Maintain strict hand hygiene
3. Lyme Disease
The Netherlands is considered a moderate-risk area for this tick-borne disease.
High-risk areas and seasons
- Hiking trails, grasslands, forests
- Peak season: April–October
Prevention strategies
- Wear long sleeves and long pants
- Avoid skin exposure
- Use tick repellent containing 30–35% DEET
Related medications
| Medication | Use | Notes |
|---|---|---|
| Dover Tick Repellent Spray | Tick and mosquito prevention | Apply to clothing and skin in advance |
| DEET-based cream | Direct skin application | Choose ≤12% concentration for children |
Pharmacist's note Lyme disease is caused by Borrelia bacteria. Erythema migrans (bull's-eye rash) typically appears 3–30 days after a tick bite. Early detection and antibiotic treatment are critical. Leave tick removal to healthcare professionals.
4. Other Viral Infections
Norovirus and Rotavirus
- Prevalent in winter
- Prevent through careful handwashing
- Recovery is typically self-limiting (rehydration is important)
Water and Food Safety
Drinking Water Safety
Tap water in the Netherlands is safe to drink. It is generally considered "safe to drink directly." However, travelers may consider these options.
| Water type | Recommendation | Reason |
|---|---|---|
| Tap water | ★★★★★ | Strictly regulated by EU standards |
| Mineral water | ★★★★☆ | Option if you prefer additional assurance |
| Restaurant tap water | ★★★★★ | Equally safe |
Pharmacist's note Water intoxication (hyponatremia) is rare, but short-term travelers drinking large amounts of water should also ensure adequate salt intake.
Food Safety
Recommended food sources
- Restaurants and cafes: High sanitary standards; generally safe
- Supermarkets: Check expiration dates
