Why prepare for a trip to Greece?
Greece is one of the world’s most popular travel destinations, famous for its ancient history, Mediterranean cuisine, stunning beaches, archaeological sites, and beautiful islands.
From Athens and Thessaloniki to Santorini, Crete, Rhodes, and Corfu, millions of visitors travel to Greece every year.

Common travel-related concerns include:
- heat exposure

Many hospitals and private clinics offer:
- English-speaking staff

Preventive measures include:

Mosquitoes and vector-borne diseases
Greece is not considered a high-risk destination for tropical diseases.
However, mosquitoes are common during warmer months.
Protective measures include:
- insect repellent
- lightweight long-sleeved clothing at dusk

Occasional cases of West Nile virus have been reported in some years.

Food, water, and food safety
Greek cuisine is often considered one of the healthiest dietary traditions in the world.
To reduce the risk of gastrointestinal illness:
- choose reputable food establishments
- stay hydrated
- pay attention to food storage conditions
Tap water is generally considered safe in many parts of Greece, although some travelers prefer bottled water in certain island locations.
Key point: Most travel-related gastrointestinal illnesses are mild and resolve without complications.
Greek islands: additional health considerations
The Greek islands are among the country’s main attractions, but they present some unique considerations.
Travelers should be aware of:
- limited healthcare access on smaller islands
- possible need for boat or air transport during emergencies
- prolonged sun exposure
- steep walking routes and uneven terrain
- intense summer heat
Key point: When exploring remote areas, carry water, sunscreen, and any personal medications you may need.
Sun protection and skin health
Ultraviolet (UV) radiation can be particularly strong between late spring and early autumn.
Recommended measures include:
- sunscreen with SPF 30 or higher
- regular reapplication
- UV-protective sunglasses
- hats or caps

Key point: Significant sunburn can affect both comfort and safety during your trip.
Mental well-being during travel
