Staying Healthy on the Road: Vaccinations, Food Safety, and Travel Health for Slow Travelers
Here’s the truth about travel health: you will get sick at some point. Probably not seriously, but within the first few weeks of any long trip, something will go wrong — traveller’s diarrhoea, a respiratory infection from an overnight bus, or just the general physical fatigue of constant movement. The difference between a hiccup and a disaster is preparation. This guide covers everything from which vaccinations you actually need, to how to eat safely without wrapping every meal in paranoia, to what should be in your medical kit.
Vaccinations: What You Actually Need
Vaccination requirements vary by region, but here’s the baseline for slow travelers passing through developing countries — book a travel clinic appointment 6–8 weeks before you leave, as some vaccines need multiple doses:
- Routine boosters: Tetanus, diphtheria, polio (combined booster). Most adults need this every 10 years. Easy to overlook, essential everywhere.
- Hepatitis A: Almost mandatory for any travel outside Europe, North America, Japan, and Australia. One shot, lasts 12 months. A booster gives 20+ years. Food and water borne — very common in Southeast Asia and South Asia.
- Typhoid: Recommended for South Asia, Southeast Asia, and Africa. Oral (four pills over a week) or injection. Protects against contaminated food and water. Worth having.
- Yellow Fever: Required for entry into many African countries and parts of South America. Proof of vaccination is recorded in your “Yellow Card” (International Certificate of Vaccination). Some countries will refuse entry without it.
- Rabies: Pre-exposure rabies vaccine is expensive ($200–500 for the series) but worth it if you’re spending significant time in rural Asia or Africa. It doesn’t eliminate the need for post-bite treatment, but it buys you time to reach a clinic.
- Japanese Encephalitis: Recommended for rural travel in Asia, especially if you’re spending a month or more in agricultural areas. Two doses, expensive but serious if contracted.
Food Safety: Eat Well, Eat Safely
How to Avoid Traveller’s Diarrhoea (Most of the Time)
You will get some form of stomach upset. It’s almost unavoidable, especially in regions where local bacteria are different from what your gut is used to. But you can reduce the odds significantly:
- Eat where locals eat, not where tourists eat: High-traffic food stalls with rapid turnover have the freshest ingredients. The food sits out for hours at tourist restaurants. Busy street stalls turn over everything in minutes.
- Hot food is safe food: Street food that’s cooked fresh in front of you (stir-fries, soups, grilled meats) is almost always safe. The heat kills the bacteria. The danger is food that has been sitting at room temperature.
- Peel it, boil it, cook it, or forget it: The old traveler’s rule still holds. Raw vegetables and unpeeled fruit are the biggest risks. You can eat a mango from a street vendor — you can’t eat pre-cut fruit salad that’s been sitting out.
- Ice is usually fine in most countries: In Thailand, Vietnam, and Malaysia, ice is made commercially from filtered water. In rural India and parts of Africa, assume it’s tap water frozen. Ask. A safe rule: if the locals drink it, you can too.
Your Travel Health Kit
This is what goes in your health kit. Keep everything in a clear ziplock bag — it makes airport security easier and keeps meds dry:
- Prescription medications: Enough for your entire trip plus one month extra. Carry the prescription and keep meds in original packaging.
- Oral rehydration salts: 10–20 sachets. The single most useful item in any travel health kit.
- Antibiotics for traveller’s diarrhoea: Azithromycin (4 pills, single dose) or Ciprofloxacin. Get these from your travel clinic before you go — buying antibiotics over the counter abroad is easy but you don’t want to be figuring out dosages while sick.
- Pain relief: Ibuprofen (anti-inflammatory) and paracetamol/acetaminophen (fever). Both available everywhere but carry a small supply.
- Antihistamines: For allergies, insect bites, or mild allergic reactions. Cetirizine or loratadine.
- Malaria prophylaxis: Depending on your destination. Doxycycline is the cheapest and most commonly used. Start before entering the malarial zone and continue for 4 weeks after leaving.
- Plasters, antiseptic wipes, blister cushions: The most-used items in any health kit. Blisters from walking are the #1 health complaint of slow travelers.
- Condoms: Quality varies by country. Carry your own.
Finding a Doctor Abroad
You will need a doctor at some point. Here’s how to find a good one, anywhere:
- International clinics: Every major city in Asia, Africa, and Latin America has a clinic that caters to expats and travelers. They’re more expensive but the doctors speak English, understand travel-related conditions, and can handle insurance paperwork. Search “international clinic [city name]”.
- Hospital chains: Bumrungrad (Bangkok), Gleneagles (Kuala Lumpur, Singapore), Fortis (India), Aga Khan (East Africa). These meet Western medical standards and charge accordingly.
- Embassy lists: Your embassy’s website usually has a list of recommended doctors and hospitals. Save this before you travel.
- Pharmacists first: In most of Asia and the Middle East, pharmacists are highly trained and can prescribe basic medications. For a stomach bug, mild infection, or allergy, a pharmacist is faster and cheaper than a doctor.
Mental Health on Long Trips
Long-term travel is mentally exhausting in ways nobody talks about. Constant decision-making, language barriers, loneliness, and the pressure to “make the most of it” can wear anyone down. Here’s how to protect your mental health:
- Build rest days into every week: A “do nothing” day in a comfortable guesthouse is not a wasted day — it’s essential maintenance. Watch movies. Read. Stare at a wall. Recover.
- Keep a simple journal: Not a travel blog. Just three lines a day: what you did, what you ate, how you felt. The “how you felt” part is the important one — it helps you notice when you’re burning out.
- Stay connected: A 5-minute call with someone who knows you (not another traveler you met yesterday) is worth more than a week of sightseeing. Schedule it.
- Recognise when to stop: If you’re dreading the next destination instead of looking forward to it, you need a break. Change of pace. A slower place. A week by a beach with no plans at all.
