Greece Health and Vaccinations: CDC Shots, West Nile, Heat and Hospitals

Greece asks for no inoculations before you arrive. What counts is being up to date at home, packing medicine properly, and knowing how care is paid for if something goes wrong.

What vaccinations do you need for Greece?

None are required: there are no required inoculations for Greece. The vaccine question is therefore less about a border checkpoint and more about your own medical history, and it is worth settling before you book a flight rather than in the last week.

Greece is a country of islands, mountain villages, ancient sites and long taverna dinners, and none of that changes the picture. The official advice for travelers is simple and the same for everyone, so the sections below turn it into steps you can follow at home.

No required shots, and the water

Nobody will ask to see a vaccination card on arrival, and no shot is a condition of a visit. The water is almost everywhere safe, which spares travelers the careful habits that other destinations demand at the hotel sink or the café table.

That does not mean there is nothing to prepare. The absence of a requirement is different from the absence of a recommendation, and the recommendation is where your own planning begins. It also leaves you free to plan a trip of any shape, from a single city stay to weeks of island hopping, without adding a vaccine appointment for the destination alone.

The CDC recommendation

The U.S. State Department tells travelers to Greece to be up to date on all vaccinations recommended by the U.S. Centers for Disease Control and Prevention. In practice that means checking your routine vaccinations against the CDC schedule, the ones adults and children receive at home, and filling any gaps.

A good habit is to bring the list to a doctor or a travel clinic and go through it together. Families can do the same for each child. Doing it well before departure leaves room for a second visit if a vaccine needs more than one appointment, and it keeps the question off your mind once you are walking through the Plaka or waiting at the port in Piraeus.

Prescription medicine in your luggage

Travelers to Greece should always carry prescription medication in its original packaging, together with the doctor’s prescription. A pill organizer is handy at the hotel, but the medicine itself travels best in the box or bottle it came in, with the label showing.

This is a habit that pays off for anyone on daily medication, from blood pressure tablets to inhalers. Put the papers in the same bag as the medicine, and keep that bag with you rather than somewhere out of reach on a ferry or a bus. If you take something regularly, bring enough for the whole stay, since a pharmacy counter abroad cannot always match the exact product you use at home.

What should travelers know about health?

The main health risks in Greece come from the weather and the outdoors: summer heat, bare islands with little shade, mosquitoes, a few sea creatures and, for some people, the air in the cities. They are ordinary holiday hazards, and each one has a plain, practical answer.

Heat in Athens and on the islands

Athens has been subject to periodic summer heat waves where the temperature can reach above 100°F, which poses a risk of respiratory problems and heat stroke for some people. A day among the ruins of the city in such weather feels very different from the same walk in spring, and the stone underfoot gives no relief.

Air pollution can also be a significant problem in many destinations overseas, Greece included. Travelers with asthma or other breathing conditions may want to keep their inhaler within reach and talk with their doctor before the trip. A hat, water and a plan that does not depend on spending every hour outdoors are sensible companions in a hot city.

Little shade on the Cyclades

Many islands, especially in the Cyclades, have very little shade to ameliorate the summer heat. A path that looks like a pleasant stroll on the map can turn into an exposed walk when the sun is high, and the same holds for going on foot to a distant beach.

In hot weather it is especially important to wear a hat and sunscreen, to take water, and to avoid being caught walking during the hottest part of the day. Trails across dry hillsides, village lanes and coastal tracks all follow that rule, and a bottle of water in the bag matters more than another camera lens.

Mosquitoes and West Nile virus

Mosquitoes that transmit West Nile virus appear routinely, even in urban areas like Attica. That surprises travelers who expect the risk only in wetlands or the countryside, and it means a hotel terrace in the capital deserves the same attention as a village garden.

In infested areas, wear long sleeves and use repellents. Evening meals outdoors are one of the pleasures of a Greek trip, so a repellent in your day bag is a small price to pay for sitting under the vines a little longer.

Jellyfish and sea urchins

Jellyfish periodically infest some beaches, and their stings can be severe. The red ones are particularly dangerous. If you see jellyfish in the water, it is a reason to rethink the swim at that spot and try another stretch of coast.

Sea urchins are common along the Greek coast, usually clinging to underwater flat surfaces such as smooth rocks and sea walls. They usually inhabit shallow water, so they are easy to see. Care should be taken not to step on them, since their spines can be painful. Look before you step in from a rock ledge or a harbor wall, and keep your eyes on the bottom as you wade.

Party resorts and sexual health

Unprotected sex among visitors, with a consequent rise in sexually transmitted infections and unplanned pregnancies, is especially common at the party resorts favored by younger people, such as Ios, Malia, Kavos and Faliraki. Nights out there tend to run late and blur judgment, so it helps to decide your habits before the evening starts.

Condoms are available at any pharmacy and at many kiosks, so there is no need to pack a supply for the whole stay. The street kiosks, the periptero, are a familiar sight in Greek towns and cities.

What about pharmacies and hospitals?

Pharmacies handle everyday needs, and hospitals handle emergencies, but how you pay and what you are covered for depend on your passport and your insurance. The most useful thing to know before you go is that care abroad often starts with money, not paperwork.

Pharmacies

A Greek pharmacy, the farmakeio, is the first stop for minor complaints, and it is also where you find condoms, since they are sold at any pharmacy. Towns and cities have them in the center, and the green cross sign over the door is the thing to look for as you walk.

If you need a refill of something you take regularly, the box and the doctor’s prescription you carried in the original packaging give the pharmacist what they need to understand the product. That is why the habit of traveling with both matters so much.

Public hospitals

In public hospitals in Greece, non-emergency wards often have minimal nursing staff overnight and on weekends. A patient admitted to such a ward may find that help at night is thin, which is a good reason for travelers to know ahead of time how they would arrange extra support.

Public health care is free and universal for all EU nationals upon presentation of an EHIC card. For non-EU nationals, only emergency care is provided for free. Americans fall into the second group, so a visit that goes beyond the emergency itself is something to plan around.

Private hospitals and paying

Private hospitals in Greece usually require proof of adequate insurance or cash before admitting a patient. Most health care providers in Greece only accept cash payments, and U.S. travelers may be required to pay upfront and seek reimbursement from their insurance company.

U.S. Medicare is not accepted overseas, Greece included, so it will not cover a bill at a clinic in Athens or a hospital on an island. Patients also bear all costs for transfer to or between hospitals. Travelers choose to look at private travel health insurance before leaving, and keep the policy details where they can read them in a hurry.

Emergencies on the islands

A network of helicopter ambulances serves the islands, transporting patients who need immediate attention to the nearest island or city with a major hospital. Some small islands have no major hospital, and this network is how a serious case reaches one.

The cost of such a transfer falls on the patient, as with any transfer to or between hospitals. It is a point worth keeping in mind if your plans take you to remote islands, where the nearest major hospital may lie on another island or on the mainland.

Good to know before you go

Put your prescriptions in their original boxes, with the doctor’s papers beside them, and have your insurance details ready for the day a clinic asks for cash or proof of cover. In the Cyclades, a hat and a full water bottle belong in the bag before any beach walk, and a repellent belongs next to them for the evenings, in Attica as much as anywhere. Sea urchins on the rocks and jellyfish in the water are reasons to watch where you swim, and nights at the party resorts call for a plan made in daylight.
