Travel Health Guide: Greece — Heat, West Nile Virus, Quad-Bike Crashes, and What Most Aegean Travelers Underestimate

The 60-Second Answer for Greece Travelers

Most US travelers do not need any "exotic" vaccines for Greece. You need to be current on the routine adult vaccines (MMR, Tdap, polio, varicella, influenza, COVID-19), and the CDC recommends hepatitis A for nearly everyone, with hepatitis B as a strong selective option. Greece has no required vaccines for direct US arrivals. As a physician, my message to every patient flying to Athens, Crete, Santorini, Mykonos, Rhodes, or Corfu is this: the things that will actually hurt you in Greece are heat illness during the June through September window (the 2024 heat dome killed multiple tourists, including British TV doctor Michael Mosley in Symi), wildfires and the smoke that travels far from them (Greek wildfires burned more than 41,000 hectares in 2024 and triggered 30,000-person evacuations on Rhodes in 2023), West Nile virus across the central mainland from July through October (Greece reported 26 locally acquired human cases by August 2025, second only to Italy in Europe), traffic and quad-bike crashes (~5 ATV deaths and ~660 ATV injuries in Greece in 2024 alone), and Pelagia noctiluca jellyfish stings in the Aegean and Ionian. Pack accordingly.

CDC and WHO recommendations for Greece can change as outbreaks evolve. Always confirm current guidance close to your travel date.

Greece at a Glance: What the Risk Profile Actually Looks Like

Greece is a Schengen-area EU member, ~10.4 million residents, and one of the largest tourism economies in Europe, drawing more than 35 million international visitors in 2024 per the Greek Ministry of Tourism. For US travelers, Greece is high-volume: roughly 1.5 to 1.7 million Americans visited in 2024, concentrated in Athens, Santorini, Mykonos, Crete, Rhodes, Corfu, and a growing share heading to mainland sites like Meteora, Delphi, and the Peloponnese.

The country has a Mediterranean climate (hot, dry summers and mild winters), a long coastline of more than 13,000 km, more than 6,000 islands (227 inhabited), and a fragmented public-health geography. A traveler doing only the Athens-Santorini-Mykonos triangle has a very different risk profile from one driving through the Peloponnese in August or trekking the Vikos Gorge in October.

The strategic point: Greece is not a "tropical disease" destination. It is a heat, environment, and traffic destination, with a real but seasonal mosquito-borne disease (West Nile virus) and a small set of food, water, and marine exposures. Plan for the actual risk, not the one you imagined.

Recommended Vaccines for Greece (CDC and WHO Aligned)

There are no legally required vaccines for US travelers entering Greece. The CDC and WHO recommendations below should be thought of as the standard, with a few selective add-ons based on itinerary.

Routine vaccines you should already be current on

• Measles, Mumps, and Rubella (MMR): 2 lifetime doses if born in 1957 or later. The CDC issued a Level 1 "Measles in the Globe" travel health notice in 2026, and Europe has had repeated measles clusters tied to under-vaccinated communities and international travel. See our MMR vaccine guide for travelers.
• Tdap: Within the last 10 years (or Td/Tdap booster). See our Tdap vaccine guide.
• Polio: Adult booster if not received as an adult, given the WHO PHEIC for international polio spread. See our polio vaccine guide.
• Varicella (chickenpox): 2 doses, or documented immunity.
• Seasonal influenza: Current Northern Hemisphere formulation, especially for older travelers, cruise passengers, and group tours. See our influenza vaccine guide.
• COVID-19: Current ACIP-recommended dose.

Universally recommended for Greece

• Hepatitis A: Recommended for essentially all unvaccinated travelers. A single pre-departure dose produces roughly 95% protection within 2 to 4 weeks. The CDC continues to list Greece among countries where hepatitis A exposure is plausible through food and water, particularly in rural areas, on smaller islands, and during festivals where catering volumes are high. See our hepatitis A vaccine guide.

Selectively recommended (based on itinerary, length of stay, and risk tolerance)

• Hepatitis B: ACIP recommends universal vaccination for adults 19 to 59. For travel-specific risk in Greece, this matters for travelers who may receive medical or dental care, get tattoos or piercings, have new sexual partners, or stay long-term. Heplisav-B is the only 2-dose accelerated schedule (0, 1 month), and is the best option if your trip is close. See our hepatitis B vaccine guide.
• Rabies (pre-exposure): Selective. Greece is not a high canine-rabies country, but Greek public health has confirmed sporadic wildlife rabies in red foxes in northern and northwestern mainland Greece (particularly along the borders with Albania, North Macedonia, and Bulgaria). Pre-exposure prophylaxis is reasonable for travelers planning extended outdoor activity, mountain trekking, or volunteer work with animals. See our rabies vaccine guide.
• Tick-borne encephalitis (TBE): Selective, only for travelers spending extended time in rural and forested areas of northern Greece (Macedonia, Thrace, and the Rhodope Mountains) from April through November. The vaccine is available in Europe but is not currently FDA-approved in the US; some travelers receive it abroad. For typical Aegean island or Athens itineraries, this is not relevant.
• Typhoid: Generally not recommended for standard tourist itineraries in Greece. Selective for travelers with long stays, repeated trips to rural areas, or significant street-food and family-stay exposure off the standard tourist circuit. See our typhoid vaccine guide.

Not recommended for Greece

• Yellow fever: No yellow fever risk in Greece, and no entry requirement when arriving directly from the United States.
• Japanese encephalitis: Not present in Greece.
• Cholera: Not endemic. Standard food and water precautions are sufficient.
• Malaria pills: Not currently recommended. Greece was declared malaria-free in 1974. Public health authorities have documented sporadic, locally acquired Plasmodium vivax cases (linked to agricultural-worker contact with imported infections), but the risk to general travelers is exceedingly low.

For the full framework on which vaccines to consider for any trip, see our Travel Vaccines Guide and our Pre-Trip Health Checklist.

The Single Biggest Health Risk in Greece: Heat

If you walked into my ER in late June with a returning traveler from Crete, my first question would be: how much water were they drinking? The 2024 Greek heat dome was a real event, not media hype. Chania on Crete recorded 44.5°C (112°F) in mid-June. Multiple tourists died in a span of weeks, including the high-profile death of British physician and broadcaster Michael Mosley, who collapsed on a hike on the island of Symi at 67 years old. A 70-year-old French tourist died on a Sitia beach. An 80-year-old man was found dead near Malia. A 67-year-old Dutch tourist died crossing the Mylon gorge.

The pattern is consistent: midday or early-afternoon exertion, single travelers, water bottles found empty or absent, and the underlying physiology of heat stroke shutting down thermoregulation faster than the brain can process the warning signs.

Heat illness in plain terms

• Heat cramps: painful muscle spasms after exertion, mostly from sodium loss. Move to shade, drink electrolyte solution (oral rehydration salts, not water alone), stretch.
• Heat exhaustion: heavy sweating, weakness, dizziness, nausea, headache, body temperature 38 to 40°C (100.4 to 104°F), still cognitively intact. Stop activity, get to AC or shade, remove excess clothing, sip electrolyte solution, and place cool wet cloths on neck and groin.
• Heat stroke: medical emergency. Core temperature above 40°C (104°F), altered mental status (confusion, slurred speech, combative behavior, seizures, loss of consciousness), often hot dry skin (sweating may stop in classic heat stroke). Call 112 (the EU emergency number) immediately. Move to shade, douse with cool water, fan vigorously, place ice packs on neck, armpits, and groin. Do not wait to see if it improves.

My heat-prevention checklist for Greek summer travel

• Shift outdoor activity to before 10 a.m. and after 5 p.m. Adopt the Greek schedule: morning, siesta in the heat, late-afternoon and evening outings.
• Carry at least 1 liter of water per person per outing, more if hiking or climbing.
• Add an oral rehydration salt packet (LiquidIV, DripDrop, or pharmacist-recommended brand) to one bottle per day.
• Light, loose, light-colored clothing. Wide-brim hat. Polarized sunglasses.
• High SPF (50+) reef-safe sunscreen, reapplied every 2 hours and after swimming.
• If you are 60+, have cardiovascular disease, take diuretics, ACE inhibitors, beta-blockers, or anticholinergics, recognize that your heat tolerance is lower than you think. Plan rest days.
• Hikes in the Samaria Gorge (Crete), Vikos Gorge (Zagori), Mt. Olympus, and any caldera-rim walk on Santorini should start at sunrise and end by mid-morning in July and August.

For anyone planning multi-day hiking in Greek summer, this is not optional preparation. It is the difference between a great trip and a 4 a.m. medevac.

West Nile Virus: Greece's Most Important Mosquito-Borne Disease

This one quietly catches travelers off guard because Greece does not look like a "mosquito-borne disease destination." It is.

According to the European Centre for Disease Prevention and Control (ECDC), by August 6, 2025, Greece had reported 26 locally acquired human West Nile virus cases for the year, ranking second in Europe behind Italy (168 cases). Greece has had documented WNV transmission every season since the 2010 outbreak that killed 35 people, and Central Macedonia, Eastern Macedonia and Thrace, Attica (greater Athens), and Thessaly are the consistently affected regions. The 2025 first detections in the Attica region included Western Attica, Piraeus, and the Saronic Gulf islands, all in patients older than 65 with neuroinvasive disease.

What you actually need to know

• Vector: Culex mosquitoes, primarily Culex pipiens. These bite from dusk through dawn (different bite cycle than the daytime-biting Aedes mosquitoes that carry dengue and chikungunya).
• Season: July through October, peaking in August and September.
• Geography: Central and Eastern mainland Greece, especially around wetlands and irrigated agricultural land. The Cyclades and Dodecanese islands (Santorini, Mykonos, Rhodes, Kos) historically have low WNV reporting. Higher-risk: Thessaloniki and Central Macedonia, Larissa and Thessaly, the Evros river basin, and parts of greater Athens (especially western Attica).
• Clinical picture: 70 to 80% of infections are asymptomatic. About 20% develop "West Nile fever" (fever, headache, myalgia, fatigue, sometimes a rash). Fewer than 1% develop neuroinvasive disease (encephalitis, meningitis, acute flaccid paralysis). Risk of severe disease rises sharply with age, especially over 60, and with underlying chronic conditions.
• Vaccine: No human vaccine.
• Prevention is the entire intervention. There is no treatment beyond supportive care.

Prevention for Greece WNV risk

• DEET 20 to 30%, picaridin 20%, or PMD-based repellent on exposed skin from dusk to dawn, especially July through October. Reapply per label.
• Permethrin-treated clothing for travelers doing extensive outdoor activity in higher-risk regions.
• Air conditioning or window screens at night. If your accommodation lacks both, use a bed net.
• Empty standing water around any villa or rental: buckets, plant saucers, pool covers, kiddie pools.
• Avoid wetland trails, ponds, and irrigated farmland at dusk during peak season.

If you develop fever, severe headache, neck stiffness, confusion, or muscle weakness within 14 days of return from Greece during summer or fall, tell your physician you traveled to a WNV-active area. Diagnosis is by serology or PCR through CDC or state health labs.

Wildfires and Air Quality: A Real and Growing Concern

Wildfires are now an annual feature of Greek summers, not an outlier. The 2024 fire season included blazes in Attica, Euboea, Rhodes, and the Peloponnese that consumed more than 41,000 hectares northeast of Athens by mid-August. The 2025 season was worse on certain days: more than 150 new fires nationwide in just two days in mid-August, mass evacuations on Zakynthos, coast-guard sea rescues on Chios. The 2023 Rhodes fire forced the largest evacuation in Greek history, with nearly 30,000 residents and tourists moved (the Greek government later offered free return trips to affected tourists).

What I tell my patients planning June through September trips

• Check civilprotection.gov.gr and the daily fire-risk map before any rural or island outing during summer. The Civil Protection Risk Index uses a 1 to 5 scale; risk levels 4 and 5 mean outdoor cooking, smoking, and even certain field activities are banned.
• Save the emergency numbers: 112 (general EU emergency), 199 (fire service direct).
• Smoke can travel hundreds of kilometers. Even if the fire is not on your island, smoke and PM2.5 can spike sharply. Travelers with asthma, COPD, heart disease, or pregnancy should carry an N95 or KN95 mask, rescue inhalers in carry-on, and check aqicn.org for the local AQI.
• Have a hotel evacuation plan. Identify two ways out of your hotel, know which beach or open space is the local civil-defense rally point, keep a packed go-bag (passport, phone charger, water, medication, ID) at the door if you are in a wildfire-prone area.
• Smoke inhalation symptoms to take seriously: persistent cough, wheezing, chest tightness, hoarse voice, dark mucus or sputum, headache, nausea, dizziness, confusion. Carbon monoxide exposure from heavy smoke is real and requires emergency care.

This is not a reason to skip Greece. It is a reason to plan like the climate has changed, because it has.

Traffic and Quad-Bike Injury: The Quiet Killer in Greek Tourist Statistics

I include this section in every Greece pre-travel briefing I do. Road traffic injury is the single most common cause of preventable death and serious injury for US tourists in Greece, year after year.

The quad-bike (ATV) problem

The numbers from Greek civil protection and police data: roughly 31,000 ATVs operate on Greek roads, generating 5 ATV deaths and more than 660 ATV injuries in 2024 alone. Mykonos, Santorini, Naxos, Paros, Ios, and Rhodes are the islands where tourist quad-bike rentals are most concentrated and where the road geometry is least forgiving. Roads are narrow, winding, often cliff-adjacent with no guardrails, poorly lit at night, and full of potholes, gravel patches, and blind switchbacks. ATVs have a high center of gravity and roll easily.

A high-profile 2025 case: Tom Greenwood, the 49-year-old CEO of Volt, was seriously injured on the Ano Mera to Agrilia road in Mykonos at 5:44 a.m. on August 20 when his quad bike veered off course, struck a house wall, and overturned. He survived; many do not.

My recommendation as the ER doctor cleaning up after these injuries

If you must rent a quad, scooter, or motorbike in Greece:

1. Wear a real helmet, every time, every distance, even for a 5-minute ride. Helmet rates among injured ATV riders in Greece are below 30% per police data.
2. Get the rental in daylight. Drive the route once before sundown so you know the turns.
3. Never ride two-up on a single-passenger quad. Half the serious crashes I see involve a second passenger on a vehicle rated for one.
4. No alcohol. Greek BAC limit is 0.05 (lower than US 0.08), and most fatal tourist crashes involve any amount of alcohol.
5. Confirm your travel insurance actually covers ATV and motorcycle accidents. Many policies exclude them by default. See our Do I Need Travel Insurance guide.
6. If you would not ride a quad on a winding cliff road at home, consider a hired car-and-driver, taxi, or local bus instead. The cost difference is small. The injury difference is enormous.

Standard road travel

Greek roads are improving but motorway driving (Athens to Thessaloniki on the A1, the Egnatia Odos through northern Greece, the new Olympia Odos on the Peloponnese) is much safer than mountain or island roads. Honking, lane discipline, and roundabout behavior differ from US norms. Drive defensively, especially at night.

Marine and Beach Hazards in the Aegean and Ionian

The Mediterranean is generally a forgiving sea, but a small number of exposures account for most clinical visits.

Pelagia noctiluca (purple jellyfish, "mauve stinger")

This is the most clinically important Mediterranean jellyfish and the most common sting I see in Greek-returning travelers. Painful local reaction lasting 1 to 2 weeks, redness, swelling, and sometimes a long-track lash mark. Both the bell and tentacles sting. Even dead, beach-stranded jellyfish can sting bare feet.

First aid (Pelagia noctiluca):

1. Get out of the water.
2. Rinse with seawater, not fresh water. Fresh water can rupture remaining nematocysts and release more venom.
3. If you have vinegar (the Greek beach answer is often a small bottle of xidi from the taverna), apply it for 30 seconds to deactivate stinging cells.
4. Carefully remove visible tentacles with tweezers or the edge of a credit card, not bare hands.
5. Immerse in hot water at 40 to 45°C (104 to 113°F) for 30 to 90 minutes. This is the most evidence-based step for pain control and venom inactivation in Mediterranean jellyfish stings.
6. Topical 1% hydrocortisone, oral antihistamine (cetirizine, diphenhydramine), and over-the-counter pain control as needed.
7. Seek medical care if: large surface area involved, sting near eye or mouth, signs of allergic reaction (hives elsewhere, lip or tongue swelling, shortness of breath, fainting), or if pain is uncontrolled after appropriate first aid.

Sea urchins (mostly Arbacia lixula, black; and Paracentrotus lividus, edible)

Walk anywhere on rocky Greek shoreline and the risk is real. Black urchin spines break off in skin, are difficult to remove, and can cause infection or chronic granuloma if left.

First aid (sea urchin):

1. Remove visible spines with tweezers. Soak in vinegar for 15 to 30 minutes (helps dissolve embedded fragments).
2. Hot water immersion 40 to 45°C for 30 to 60 minutes for pain.
3. If spines are deep, near a joint, in a finger or toe pad, or you cannot fully remove them, see a local clinic for removal. Retained spines can cause infection and chronic pain.
4. Update tetanus (Tdap) if you are not within 5 years.

The fix: rubber-soled water shoes for any swim entry on rocky beaches, jetties, or piers.

Weeverfish (Trachinus draco)

Small fish that bury in sand in shallow water. Venomous dorsal spine. Sting is intensely painful for hours, sometimes days. Treatment: hot water immersion at 40 to 45°C for 30 to 90 minutes. Seek care if local symptoms worsen, you have any systemic symptoms, or signs of secondary infection.

Drowning, currents, and cliff jumping

Drowning is consistently one of the top causes of tourist death in Greece. Risk factors: alcohol, swimming alone, late-night beach swims, unfamiliar currents (the Aegean has strong meltemi winds in July and August), and cliff jumping into water of unknown depth. The Wandr ER position is consistent: alcohol and ocean swims do not mix, and cliff jumping into water you have not personally checked is unacceptable risk in any geography.

Food, Water, and Traveler's Diarrhea in Greece

Greek food safety is generally good in major tourist destinations, but the risk is not zero, and the geography matters.

Tap water

• Athens, Thessaloniki, mainland major cities: tap water is safe. The Athens water utility (EYDAP) and Thessaloniki Water (EYATH) meet EU drinking water standards.
• Most major islands (Crete, Rhodes, Corfu, Kos): generally safe in main resort areas; many travelers prefer bottled out of taste preference.
• Smaller islands and rural areas (parts of Santorini, Mykonos, many Cyclades, small Dodecanese, parts of the Sporades and Ionian): Tap water quality is variable. Many islands rely on desalination, well water, or imported supply, and locals frequently use bottled water for drinking. Default to bottled or filtered water on small islands.

Food safety

• Cooked, hot, fresh food in busy tavernas is low risk.
• Raw seafood (carpaccio, sushi, oysters) carries the highest enteric infection risk; choose well-reviewed restaurants.
• Unpasteurized cheese is common in mountain villages; if you are pregnant or immunocompromised, ask before ordering.
• Salads and raw vegetables in major tourist establishments are generally safe. Be more cautious in rural tavernas or at festivals with high-volume catering.

Traveler's diarrhea (TD)

A traveler's diarrhea episode in Greece is more often viral or food-related than the bacterial picture you would expect in India or Egypt. Most cases resolve within 48 to 72 hours with rest and fluids.

Greece-specific TD kit (what I tell my patients to carry):

• Loperamide (Imodium) 2 mg tabs for symptom control, max 8 mg/day.
• An antibiotic for the moderate-to-severe case: azithromycin 500 mg once daily for 1 to 3 days is reasonable first-line, given the variable fluoroquinolone resistance picture across the Mediterranean. For comparison, see our Cipro vs Azithromycin for Traveler's Diarrhea guide.
• Oral rehydration salts (ORS) for the volume-depleted case, especially in heat.
• Ondansetron 4 mg ODT for nausea and vomiting.

Take antibiotics only if symptoms are severe (fever, bloody stools, profuse watery diarrhea, persistent vomiting, dehydration), not for routine soft stools. Mild cases recover with hydration alone.

For the full framework on managing TD, see our Traveler's Diarrhea complete guide.

---

Motion Sickness and Aegean Ferry Travel

Greek island travel almost always involves ferries, and the Aegean in the meltemi season (mid-July through mid-August) can produce 6-foot to 12-foot swells. If you have any history of motion sickness, the worst time to find out you are sensitive is mid-passage from Piraeus to Santorini.

Options, from least to most aggressive:

• Acupressure wristbands (Sea-Bands) for mild susceptibility.
• Meclizine (Bonine, Antivert) 25 mg, 1 hour before departure. Drowsiness mild to moderate.
• Dimenhydrinate (Dramamine) 50 mg, 1 hour before departure. More drowsy than meclizine.
• Scopolamine transdermal patch (the most effective option for multi-day exposure). Apply behind the ear 4 hours before departure, lasts 72 hours. Prescription only in the US. For a full medication comparison, see Scopolamine Patch vs Dramamine and the broader Motion Sickness While Traveling guide.

If your trip involves a Cyclades island-hop (Santorini, Mykonos, Naxos, Paros, Milos) or a Dodecanese run (Rhodes, Kos, Symi, Patmos), having the scopolamine patch on hand is the single most powerful prevention. Wandr clinicians can call a prescription in to your local pharmacy for pickup before departure.

Region-by-Region Notes

Athens and Attica

Year-round destination with summer being the most challenging because of heat, urban smog (especially during meltemi-suppressed weeks), and the wildfire smoke that hits the Athens basin from surrounding mountains and coastline. Tap water is safe. Pharmacies are widespread; the green-cross sign indicates a working pharmacy, and rotating overnight pharmacies (efimerefon) cover off-hours. The Athens metro is safe and clean; taxis are metered (insist on the meter or use Beat/Uber).

Santorini

The defining Santorini risk is heat and the caldera-rim walk between Fira and Oia (about 10 km, no shade in many sections). Start at sunrise. Carry 2 liters of water per person. The donkey-cliff path in Fira is steep and exhausting in summer; the cable car is the safer option. Tap water is non-potable on most of the island; use bottled. Volcanic island, with active monitoring of the Santorini caldera by the Hellenic Volcanological Society; no recent eruption (the last was 1950), but seismic swarms occur (notably the 2025 Aegean swarm centered between Santorini and Amorgos). Follow Greek Civil Protection guidance if seismicity is elevated.

Mykonos

ATV/quad-bike injury capital of the Greek islands. Wind and sun exposure are the daily risks; nightlife dehydration plus heat is the typical ER presentation. Same tap-water advice as Santorini.

Crete

The largest island and the most diverse risk profile. Summer heat is extreme (Chania recorded 44.5°C in June 2024). Samaria Gorge is one of the great hikes in Europe but starts at altitude (~1,200 m), descends 16 km, and is grueling in heat. Start at sunrise, carry water and electrolytes, and exit at Agia Roumeli. West Nile virus has been reported in Crete in past seasons. Bring repellent. Tap water in cities (Heraklion, Chania, Rethymno) is generally safe; on the south coast and in mountain villages, default to bottled.

Rhodes and the Dodecanese

Wildfire risk during summer (the 2023 evacuations were here). Check daily Civil Protection updates June through October. Standard Aegean island health profile.

Corfu and the Ionian Islands

Cooler and greener than the Aegean, slightly higher rainfall, more vegetation, more mosquitoes (though WNV reporting has been historically lower in the Ionian than in Central Macedonia or Attica). Watch for cliff-diving injuries at popular beach locations (Porto Timoni, Kassiopi).

Thessaloniki and Central Macedonia

This is the Greek WNV hotspot. Highest reported case rate in the country in most seasons. Bring repellent; use AC and screens at night; the urban canal areas and surrounding agricultural belt are higher exposure.

Meteora, Vikos Gorge, Mt. Olympus, Zagori

Hiking-heavy mainland destinations. Tick exposure becomes relevant in spring and early summer (April through July). Tick-borne encephalitis (TBE) in northern Greece is a low but real risk for prolonged outdoor stays. Standard tick precautions: long pants tucked into socks, permethrin-treated clothing, daily tick checks, and prompt removal.

Greek border regions (northern mainland)

Sporadic wildlife rabies has been confirmed in red foxes near the borders with Albania, North Macedonia, and Bulgaria. Rabies pre-exposure prophylaxis is reasonable for travelers planning extended trekking in these border ranges.

Building a Greece-Specific Travel Health Kit

This is my standard recommendation for a 1- to 3-week Greek itinerary in summer:

Vaccines completed before departure (per the vaccines section above).

Sun and heat:

• SPF 50+ broad-spectrum reef-safe sunscreen (3 oz minimum)
• Lip balm with SPF
• Wide-brim hat, polarized sunglasses, light long-sleeve UPF shirt
• Cooling neck wrap
• Oral rehydration salt packets (10 to 15)
• Reusable insulated 1L water bottle

Insect protection:

• DEET 30% (or picaridin 20%) for skin
• Permethrin-treated socks and one shirt (for hikers and travelers heading to Central Macedonia or rural mainland)

GI kit:

• Loperamide (Imodium) 2 mg, 12 tablets
• Ondansetron 4 mg ODT, 6 tablets
• Azithromycin 500 mg, 3 tablets (prescription)
• Probiotic of choice
• Pepto-Bismol chewables

General health:

• Ibuprofen 200 mg and acetaminophen 500 mg
• Antihistamine (cetirizine 10 mg and diphenhydramine 25 mg)
• 1% hydrocortisone cream
• Bacitracin or mupirocin ointment
• Adhesive bandages, gauze, medical tape, sterile saline wipes, tweezers
• Blister care (Compeed or moleskin)
• Personal prescription medications in original labeled bottles plus a written list of generic names and doses

Motion sickness (for ferry-heavy trips):

• Scopolamine patch (prescription) or meclizine 25 mg

Wildfire / air quality:

• N95 or KN95 mask (2 to 3)
• Asthma rescue inhaler if applicable (in carry-on)

Documentation:

• Travel insurance card with ATV coverage confirmed if you will rent
• Emergency contact list including hotel and EU 112
• Photocopies of passport and ID

When and How to Get Care in Greece

Greece is an EU member state with a developed healthcare system. Three things US travelers should know:

1. Pharmacies (farmakeio) carry essentially everything a US drugstore carries, often without a prescription for items that require one in the US. The green-cross sign indicates an open pharmacy. Rotating overnight pharmacies are listed on a posted schedule in each pharmacy window. English is widely spoken in tourist areas. Buying ORS, antihistamines, NSAIDs, and most topicals is straightforward.
2. Public hospitals are universally available. EU citizens use the EHIC card. US citizens pay out of pocket and submit to travel insurance. Major hospitals: Evangelismos and KAT in Athens, AHEPA in Thessaloniki, Venizeleio in Heraklion (Crete), Andreas Papandreou in Rhodes. Quality of care is solid for emergencies; expect longer waits than in private clinics.
3. Private clinics and 24-hour clinics are common in tourist areas (Mykonos has private clinics like Mykonos Medical, Santorini has the Santorini Hospital and several private clinics). Costs are higher but quality and English fluency are usually better than the public system for non-emergency care.

Emergency numbers:

• 112: EU general emergency (police, fire, ambulance). English-speaking dispatchers.
• 166: Greek ambulance direct.
• 199: Greek fire service direct.
• 100: Greek police direct.

Severe trauma, stroke, MI, severe burns, or major hemorrhage warrant immediate 112 activation and the closest public ED. For chest pain or stroke symptoms, the public system is faster than private.

For emergencies requiring repatriation or higher-level care, travel insurance medevac is the lever that pays the $50,000+ flight home. Verify your policy before you go.

How Wandr Helps Before Your Greece Trip

Wandr Health is a physician-founded travel health platform built around the actual workflow patients need before a trip. For Greece specifically:

• Pre-trip health check. Free profile review by our clinical team; tells you exactly which vaccines and medications you need for your itinerary.
• Prescription medications. Our clinicians call prescriptions in to your local pharmacy for pickup before departure. Most relevant for Greece: scopolamine patches for ferry trips, azithromycin for the TD kit, ondansetron for nausea, and ORS or other supplies as needed.
• Travel vaccines. For vaccines like hepatitis A, hepatitis B, MMR booster, Tdap, polio, and influenza, Wandr books your appointment at a partner pharmacy near you (currently Walgreens). The pharmacist administers the vaccine on-site, no separate doctor visit. Pick a Walgreens location and time; the pharmacist administers your travel vaccines on-site.
• Travel insurance. Wandr can pair your prescription and vaccine workflow with a travel-medical policy that covers medevac and high-risk activity (verify ATV coverage explicitly if relevant).

A typical Greece-bound traveler completes the entire prescription and vaccine prep through Wandr in under 30 minutes, online, with no travel-clinic appointment, saving the typical $100 to $200 travel-clinic consultation fee.

FAQ: Greece Travel Health

Q: Do I need any vaccines to enter Greece from the US? A: No. Greece has no vaccine entry requirements for direct US arrivals. CDC recommends being up to date on routine vaccines (MMR, Tdap, polio, varicella, influenza, COVID-19) plus hepatitis A for nearly all travelers, with hepatitis B selective. Yellow fever, JE, and malaria are not relevant for Greece.

Q: Is West Nile virus really a risk in Greece? A: Yes. Greece reported 26 locally acquired human WNV cases by August 2025, second only to Italy in Europe. The risk is concentrated in Central Macedonia, Eastern Macedonia and Thrace, Attica (greater Athens), and Thessaly, with the season running July through October. There is no vaccine. Use DEET or picaridin from dusk through dawn, sleep with screens or AC, and avoid wetlands and irrigated farmland at dusk in peak season.

Q: How dangerous is the summer heat in Greece? A: Significant. The 2024 heat dome killed multiple tourists, including British physician Michael Mosley on Symi. Crete (Chania) hit 44.5°C in June 2024. Heat illness is preventable: shift outdoor activity to before 10 a.m. and after 5 p.m., carry water and oral rehydration salts, wear sun-protective clothing, and recognize heat stroke early (confusion, altered mental status, body temp >40°C — call 112 immediately).

Q: Should I rent a quad bike (ATV) on Mykonos or Santorini? A: My ER answer is: probably not. Greek police data shows ~5 ATV deaths and ~660 ATV injuries in 2024 alone, with Mykonos and Santorini among the highest-risk islands. If you do rent, wear a real helmet, drive the route in daylight first, never ride two-up, no alcohol, and verify your travel insurance covers ATV accidents (many policies exclude them by default).

Q: Is the tap water safe to drink in Greece? A: In Athens, Thessaloniki, and most major mainland cities, yes. On smaller islands and in rural areas (parts of Santorini, Mykonos, many Cyclades and Dodecanese), tap water quality is variable, and bottled or filtered water is the safer default. When in doubt on an island, ask your hotel directly.

Q: Do I need malaria pills for Greece? A: No. Greece was declared malaria-free in 1974. Sporadic locally acquired Plasmodium vivax cases have been documented in agricultural-worker contexts, but the risk to general tourists is essentially zero.

Q: What should I do if I get stung by a Pelagia jellyfish? A: Rinse with seawater (not fresh water). Apply vinegar for 30 seconds. Carefully remove tentacles with tweezers. Immerse the area in hot water at 40 to 45°C (104 to 113°F) for 30 to 90 minutes for pain control. Topical hydrocortisone and oral antihistamine help with the rash. Seek care if the sting is large, near the face or eyes, or if you develop hives elsewhere or shortness of breath.

Q: How do I deal with seasickness on the Greek ferries? A: For Aegean ferry travel in the meltemi season (July through August), the scopolamine patch is the most effective option (apply 4 hours before departure, lasts 72 hours, prescription only). Meclizine or dimenhydrinate work for shorter trips. Wandr clinicians can call a scopolamine prescription in to your local pharmacy for pickup before you go.

Q: What is the emergency number in Greece? A: 112 is the EU-wide emergency number, with English-speaking dispatchers, used for police, fire, and ambulance. 166 reaches Greek ambulance directly. 199 is fire service. 100 is police.

Q: Will my US prescriptions work in Greek pharmacies? A: A Greek pharmacist will fill a US prescription only at their discretion and typically for the local brand-name equivalent. The simpler path: bring your full trip supply in the original labeled bottle, plus a written list of generic names and doses. For new prescriptions needed mid-trip (rare), the pharmacy can often dispense common medications without a US prescription, but expect to pay out of pocket.

Q: Is wildfire season going to affect my trip? A: Possibly. Greek wildfire activity has been intense in 2023, 2024, and 2025. Check civilprotection.gov.gr daily during June through September, save 112 and 199 in your phone, carry an N95 mask and rescue inhaler if you have asthma, and have a hotel evacuation plan. Most travelers are not directly affected, but smoke can travel hundreds of kilometers, and even resort areas can be evacuated on short notice.

Bottom Line

Greece is one of the great travel destinations in the world, and the health risk for most US travelers is genuinely manageable. The vaccines you need are mostly the ones you should already have, plus hepatitis A. The risks that actually injure or kill tourists in Greece are not exotic infections; they are heat, wildfire smoke, quad-bike crashes, drowning, and the occasional West Nile mosquito bite in the central mainland.

Plan for those real risks. Get the routine vaccines updated. Pack the heat, GI, and motion-sickness kit. Verify your travel insurance covers ATV use if you plan to rent one. And go.
