Europe

Tick-borne encephalitis is a viral infection of the brain transmitted by Ixodes ricinus ticks in forested areas of Central, Eastern, and Northern Europe. The TBE risk zone spans from France east through Germany, Austria, Switzerland, Czech Republic, Slovakia, Poland, the Baltics, Scandinavia, and extends into Russia and China. Risk is highest from April through October when ticks are active. The TBE vaccine (not routinely available in the US — must be obtained before or in Europe) provides excellent protection. Tick checks after every outdoor outing and permethrin-treated clothing are essential for hikers and campers.

Lyme disease (Borrelia burgdorferi) is the most common tick-borne infection in Europe — transmitted by the same Ixodes tick as TBE. Unlike TBE, there is currently no vaccine available for adults in the US. European Lyme disease strains (B. burgdorferi sensu lato) differ slightly from North American strains and may cause different clinical presentations. Risk spans all forested areas across the continent. The key protective measures are tick avoidance: permethrin clothing, DEET on exposed skin, staying on paths, and thorough tick checks. If a tick is found, remove it promptly with fine-tipped tweezers and monitor for the characteristic expanding rash (erythema migrans).

Dengue has emerged in Southern Europe in ways that would have been unthinkable a decade ago. Aedes albopictus (tiger mosquito) is now established in Spain, France, Italy, Croatia, Greece, Portugal, and Madeira. Local dengue transmission has been confirmed in southern France, parts of Italy, Croatia, and Madeira (which has experienced significant outbreaks). As of 2024, dengue risk in southern European countries has increased significantly — check CDC travel notices before travel to Mediterranean destinations, particularly in summer months.

West Nile virus (WNV) is now well-established in Southern and Eastern Europe — particularly Greece, Italy, Serbia, Romania, and the Balkans. Transmitted by Culex mosquitoes that bite primarily at dusk and dawn, WNV is usually mild but can cause severe neurological illness in older adults and immunocompromised travelers. No vaccine exists. Use DEET during evening hours in affected countries — particularly near standing water and agricultural areas.

Food and water safety varies significantly across the continent. In Western and Northern Europe, food safety standards are generally at least as high as in the US. In parts of Eastern Europe, the Balkans, and countries with less developed infrastructure, typhoid and hepatitis A precautions are advisable. Hepatitis A vaccination is recommended for travel to Eastern Europe, Turkey, and the Balkans. Tap water may be unreliable in parts of Albania, Kosovo, Moldova, and rural Romania. See our Food & Water Safety guide.

Southern Europe now regularly experiences extreme heat events — temperatures above 40°C (104°F) in Spain, Italy, Greece, and Portugal during summer. The 2003 European heatwave killed 70,000+ people; such events are becoming more frequent with climate change. Older adults, young children, and travelers with cardiovascular or respiratory conditions are at highest risk. Avoid outdoor activity between 11am and 4pm in summer, hydrate constantly, and know the signs of heat exhaustion and heat stroke.

Rabies is considered eliminated in Western and Northern Europe (except bats). However, it remains present in parts of Eastern Europe — particularly Ukraine, Belarus, Russia, and parts of the Balkans. Turkey has a significant stray dog population with rabies risk. Pre-exposure prophylaxis is recommended for rural travel, cycling/hiking in Eastern Europe and Turkey, and for travelers who may be far from prompt post-exposure care. Bat rabies exists across Europe — never handle bats.

Influenza, COVID-19, and other respiratory illnesses circulate year-round in European tourist hubs — particularly in crowded museums, public transport, and accommodation. Ensure COVID-19 boosters and annual influenza vaccination are current before departure. Consider carrying surgical masks for high-density indoor situations. Legionella risk from hotel water systems (particularly in older Mediterranean accommodation) is a background concern worth noting for immunocompromised travelers.

Most European mountain destinations are at altitudes below 3,000 m — significantly lower than Latin American or Himalayan risks. AMS is possible in the higher Alps (Mont Blanc 4,808 m, Monte Rosa 4,634 m) and for skiers rapidly ascending to 2,500–3,000 m ski resorts. The risk is much lower than Andean or Himalayan destinations. Standard altitude precautions apply for serious alpine trekking. See our Altitude Sickness guide.

Clothing Treatment

Treat clothing with 0.5% permethrin spray before hiking. Wear long trousers tucked into socks and long sleeves in forested areas. Light-coloured clothing makes tick spotting easier. Pre-treated clothing (Insect Shield) remains effective through multiple washes.

Repellent on Exposed Skin

Apply DEET (30–40%) or picaridin (20%) to all exposed skin — particularly ankles, wrists, and neck. Reapply every 4–6 hours. Ticks do not fly or jump — they attach from vegetation as you brush past. Stay on marked paths where possible.

Daily Tick Checks

After every outdoor outing, conduct a thorough whole-body tick check — including scalp, behind ears, armpits, groin, and between toes. Check children and pets too. The sooner a tick is removed, the lower the transmission risk — most TBE and Lyme transmission requires tick attachment of several hours.

Tick Removal

Use fine-tipped tweezers or a tick removal tool. Grasp the tick as close to the skin as possible and pull upward with steady, even pressure. Do not twist, crush, or apply heat/petroleum jelly. Clean the bite site with antiseptic. Monitor for a spreading rash over the next 30 days.

Get Proper Travel Insurance

This is the single most important health preparation for Europe. Standard US health plans often provide minimal international coverage. Purchase a comprehensive travel health insurance policy that explicitly covers emergency hospital treatment, specialist consultations, and medical evacuation in all countries on your itinerary — including lesser-visited Eastern European nations.

Take Ticks Seriously

The vast majority of US tourists hiking in Austria, Czech Republic, or Germany are unaware of TBE risk. If you are planning any forested walking, cycling, or camping in Central or Eastern Europe between April and October, obtain the TBE vaccine and use permethrin-treated clothing. This risk is real, preventable, and consistently overlooked.

Medications — Know the Rules

Many common US medications are available over the counter in European pharmacies. However, some familiar brand names do not exist in Europe (Tylenol is Paracetamol; Advil is Ibuprofen; NyQuil equivalents vary). For controlled substances, carry the original labelled prescription bottle and a physician letter. Some medications freely available in the US require prescription in European countries.

Summer Heat in Southern Europe

Temperatures in Spain, Italy, Greece, and Portugal regularly exceed 40°C in July and August. Many older buildings and budget accommodation in Southern Europe lack air conditioning. Avoid midday outdoor sightseeing in peak summer, carry water at all times, and know the signs of heat exhaustion. Heat-related deaths among tourists are reported every summer in this region.

Water Safety — Most of Europe is Fine

Tap water is safe to drink in the vast majority of European countries — including all EU member states in Western, Northern, and Central Europe. Be more cautious in Albania, Kosovo, Moldova, parts of rural Romania, and Ukraine — use bottled water in these areas. In Mediterranean countries, water is technically safe but heavily chlorinated — locals often prefer bottled water for taste rather than safety.

Pollen Allergies — Spring Travel

Spring in Europe — particularly March through May — brings intense pollen seasons across much of the continent. The Mediterranean spring, Alpine meadow season, and UK/Northern European grass pollen season can significantly exacerbate allergic rhinitis and asthma. Allergy sufferers should carry extra antihistamines and inhaler supplies and check local pollen forecasts.

Road Safety — Driving in Europe

Traffic injury is one of the most common causes of traveler death in Europe — particularly for US tourists renting cars abroad. Remember: traffic flows on the left in the UK, Ireland, Malta, and Cyprus. Speed limits are in km/h. Blood alcohol limits are lower than in most US states (0.05% in most EU countries). Some historic city centres have restricted driving zones (ZTL in Italy).

Know Your Schengen Rights

US citizens can stay in the Schengen Area for up to 90 days in any 180-day period without a visa. From 2025, the EU's ETIAS pre-travel authorisation will be required (similar to Australia's ETA). Always carry your passport — some EU countries require it even for internal travel. Non-Schengen countries (UK, Romania, Bulgaria) have their own entry rules.
