Belgium travel health guide

The data behind Belgium's score 81.1/100 · #9 of 30

Eight metrics, scored 0–100 and weighted per the index methodology. Evidence and sources shown per metric.

Can you drink the tap water in Belgium? Safe to drink

Yes — tap water is safe to drink right across Belgium: in Brussels, Antwerp, Ghent, Bruges and everywhere between. It meets the EU Drinking Water Directive and is monitored closely, so you can drink it, make ice with it, brush your teeth and rinse salad without concern.

What varies is taste and hardness, not safety. Broadly, the water is harder and more mineral in the south — much of Wallonia and Brussels draw on chalk and limestone sources — and softer in parts of Flanders, so the same tap can taste noticeably different over a short journey. Hard water is entirely healthy; it simply furs up the kettle and carries a more mineral flavour.

Bottled water is popular out of habit, and Belgians buy plenty of it, but that’s preference rather than necessity. For infant formula the tap is fine; if you’re somewhere with very hard water and would rather use a low-mineral option for a baby, bottled low-mineral water is cheap and sold everywhere. Otherwise, refill from the tap and save the money and the plastic.

Mosquitoes and insect risk in Belgium Low

Belgium is a low-risk country for mosquitoes and scores well on this metric. Native species can nag on warm, damp summer evenings — near the canals, ponds and green edges of the cities and in wetter rural corners — but they carry no disease.

The one development worth noting is the Asian tiger mosquito (Aedes albopictus), which has gained a localised, spreading foothold in Belgium. It’s closely watched: Sciensano and the Institute of Tropical Medicine monitor and treat known entry points such as used-tyre depots and “lucky bamboo” importers, and run public sighting-report campaigns. Crucially, there is no local transmission of dengue, chikungunya or West Nile virus in Belgium — the issue is the mosquito’s presence, not any disease it is currently spreading.

Protection is simple and mostly about comfort: a repellent with DEET or icaridin and covering up on still evenings. If you spot a small, distinctively black-and-white striped mosquito biting by day, you can report it to the national surveillance programme. No mosquito-related vaccination is advised for travellers.

How hot does Belgium get in summer? Low

Belgian summers are gentle and maritime — Brussels sits at around a 23°C July high — but the country shares in the occasional European heat spike. The national record, an exceptional 41.8°C, was set in July 2019, part of the same heatwave that toppled records right across the Low Countries.

Sustained heat is rare and buildings mostly lack air-conditioning, so a hot few days can feel heavy in Brussels or Antwerp, where trams and older flats warm up fast. When the interior bakes, the coast (Ostend, Knokke) and the shaded Ardennes forests to the south-east stay noticeably cooler — handy escape routes.

When temperatures climb, the authorities can trigger the national heat-and-ozone plan (plan forte chaleur / ozon- en hitteplan), and the Royal Meteorological Institute (RMI) issues weather warnings. Ground-level ozone can edge up on hot, still days, which matters if you have asthma. Drink plenty, avoid the early-afternoon sun and look in on elderly friends or relatives — but for most visitors, Belgian heat is short-lived and manageable.

Food and stomach bugs in Belgium Low

Food-safety standards are high and serious gastro illness is uncommon, so ordinary care in the summer heat is really all that’s needed. Tap water is safe, and busy, reputable kitchens keep food moving rather than sitting out.

A few Belgian favourites do involve raw or delicate ingredients worth a passing thought. Filet américain and steak tartare — both raw seasoned beef — are national staples, and the celebrated moules-frites depends on very fresh mussels. All are fine from a good kitchen, but, as with raw beef or shellfish anywhere, pregnant travellers and anyone with weakened immunity may prefer to skip the raw dishes. Frites, waffles, chocolate and beer, needless to say, threaten nothing but your waistline. Keep oral rehydration sachets handy for the rare upset.

Do you need vaccinations for Belgium? Routine (+TBE)

No special vaccinations are needed for a normal trip to Belgium. Just make sure your routine jabs are up to date — MMR (measles still circulates in Europe), tetanus-diphtheria-polio, and COVID-19 where advised.

Tick-borne encephalitis (TBE) is present only in a very limited, localised way, so the vaccine is rarely necessary — it’s a conversation for people planning a lot of forest and grassland walking in the wooded south-east, who should in any case use repellent and check for ticks. Hepatitis A, typhoid and rabies vaccines aren’t required for ordinary tourism.

Healthcare in Belgium: doctors, pharmacies & the EHIC/GHIC Moderate access

Belgium has strong, accessible healthcare and one of the highest pharmacy densities in Europe — roughly 40 pharmacies per 100,000 people — so a pharmacie / apotheek is rarely far away. Pharmacists are well trained and a sensible first stop for minor ailments, and an on-call rota (pharmacie de garde / wachtdienst) covers nights and Sundays, posted in windows and online.

One Belgian wrinkle is language: pharmacists and doctors work in Dutch (Flemish) in Flanders — Antwerp, Ghent, Bruges — in French in Wallonia, and bilingually in Brussels, with English widely spoken in the cities, especially around Brussels’ international quarters. Another is billing: you often pay the doctor up front and reclaim part of the cost afterwards, so keep receipts, and carry your EHIC (EU) or GHIC (UK) alongside travel insurance.

For routine matters — a lapsed prescription, a UTI, a nasty bite, a summer cold that won’t shift — an online consultation sidesteps both the language and the paperwork, and is usually quicker than tracking down and paying a local GP in the middle of a holiday.

Emergency numbers in Belgium 112

The number to remember is 112 — free, usable from any phone, English-speaking, and covering ambulance and fire. For the police, Belgium keeps a separate national number, 101.

For medical help that’s needed out of surgery hours but isn’t an emergency, 1733 reaches the GP on-call service. Save 112 and 101 before you travel, note the address where you’re staying, and if you’re out in the Ardennes, a landmark or a GPS pin will help responders find you faster.
