Health Preparation Six Weeks Before a Package Tour

Package tours move on a timetable that does not wait for anyone to feel better. That makes the six weeks before departure more important than they are on an independent trip, where you can rest for a day. None of what follows is medical advice: it is a list of what to ask, when, and whom. A travel clinic or your own doctor should make the actual decisions.

Why six weeks

Six weeks is roughly the point at which a travel-clinic appointment still leaves time to act on what it tells you. Some vaccinations need more than one dose spaced apart; some take a couple of weeks to become effective; a few destinations require a certificate that must be dated a set number of days before entry. Prescriptions take time to fill in the quantities a long trip needs. Book the appointment first and organise the rest around it. If departure is closer than six weeks, book the appointment anyway: clinics deal with short notice regularly and will tell you what is still useful.

The travel-clinic appointment: what to bring

• The itinerary, with the countries, regions and dates. Advice differs between a capital city and a rural area, and between the dry and wet seasons.
• Your vaccination history, or as much of it as you can find.
• A list of current medications and existing conditions.
• The tour's activity list: altitude, diving, trekking, wildlife areas, freshwater swimming. Each changes the advice.
• Questions about the itinerary's physical grading, if you are unsure you meet it.

Routine versus destination vaccinations

Clinics tend to separate two ideas. Routine vaccinations are the ones recommended for everyone at home, which may need a booster regardless of travel. Destination-specific vaccinations are recommended, or in some cases required, because of where you are going and what you will do there. The clinic decides which apply to you; this article deliberately names none. Two things are worth understanding as a traveller.

• 'Required' and 'recommended' are different. A required vaccination is an entry condition and comes with a certificate that border officials may ask for, sometimes only if you have arrived from certain countries. A recommended one is a health decision made with the clinic.
• Tour operators sometimes list vaccination guidance in pre-departure notes. Treat it as a prompt to ask the clinic, not as the answer. Operators are not medical services and the guidance is often generic.

Altitude on the itinerary

Many popular tours reach heights where altitude sickness is a real risk: the Andes around Cusco and Lake Titicaca, parts of the Himalaya, Ethiopia's highlands, the Tibetan plateau, some East African peaks. Itineraries handle this with acclimatisation days, usually described as 'rest day' or 'gentle walk to acclimatise', and by ascending gradually rather than flying straight to the highest point.

• Check where the tour sleeps on the first night at altitude and how much higher the itinerary climbs each day afterwards. A tour that flies into a high city and does a strenuous walk the same afternoon is asking a lot of most bodies.
• Ask the operator what happens if a traveller cannot continue: descent arrangements, whether a leader stays with the group, and any extra cost.
• Discuss the altitude profile with the clinic or doctor, especially with any heart, lung or blood-pressure condition. Do not rely on fitness; altitude sickness does not track with it.
• Plan the days before altitude to be quiet, and arrive hydrated and rested rather than straight off an overnight bus.

Food and water: the habits that actually matter

Most tour-related illness is stomach upset, and most of it comes from a small number of habits rather than from anything exotic. Advice varies by country and the clinic will tailor it, but a few points come up almost everywhere.

• Water: in many destinations, tap water is not safe for visitors even where locals drink it. Use bottled or treated water for drinking and teeth-cleaning, and ask the leader on day 1 what the local practice is. Ice is only as safe as the water it was made from.
• Hot and busy: food that is cooked through and served hot, from a place with a queue of locals, is the usual guidance. Buffet food that has sat lukewarm is a frequent cause of trouble on tours, including in good hotels.
• Peel it or cook it: fresh salads and unpeeled fruit washed in local water carry the same risk as the water.
• Hand hygiene before eating, with soap or sanitiser, matters more than any single food choice.
• Tell the leader early if you are unwell. A day of rest with fluids is usually all that is needed, and the group's schedule can absorb one person missing an afternoon.

For anything that lasts more than a day or two, involves fever or blood, or affects a child or someone with a health condition, see a doctor. The insurer's assistance line can help find one.

Medication supply and prescriptions across borders

This is the area that catches otherwise careful travellers, because the rules differ between countries and are enforced at borders rather than explained in advance.

• Carry enough of any regular medication for the whole trip plus a margin for delays, in the original packaging with the pharmacy label.
• Carry a copy of the prescription and, for anything controlled or injectable, a letter from the prescribing doctor stating what it is and why you take it. Some countries require this to be translated or notarised.
• Some medicines that are ordinary at home are restricted or banned in certain countries. The destination's embassy website, or the clinic, can tell you which. Check this well before departure, not at the airport.
• Split the supply between hand luggage and a second bag if the quantity allows. Do not check all of it in.
• Ask the pharmacist about storage. Some medications do not tolerate the heat of a vehicle boot or a tropical hotel room.
• If you need a medicine during the trip, pharmacies in many countries sell over the counter what needs a prescription at home, and the reverse. The tour leader will know where the nearest reputable pharmacy is.

Travelling with allergies

Group meals are set menus, ordered in advance for a table of twelve or forty, in a kitchen that may not read the language your allergy is written in.

• Tell the operator at booking, in writing, and confirm the leader has it on the first day. Operators can cater for common allergies on group meals; they cannot cater for ones they do not know about.
• Carry a printed allergy card in the local language. The important part is a translation checked by a native speaker.
• Carry any prescribed emergency medication on your body, not in the bus, and tell the leader where it is. Ask your doctor how much to carry and how to store it in heat.
• Ask the leader to check ingredients rather than asking a waiter yourself. The leader's language and relationship with the restaurant tends to get a more accurate answer.
• Expect some free-time meals to be harder than group meals, and plan those in advance.

Mobility and fitness grading

Operators grade itineraries on a scale of their own, typically from 'easy' through 'moderate' to 'challenging', or numbered levels. The scales are not comparable between operators, and the descriptions are written for the average of the people who book that trip.

• Ask for specifics: longest walking day in hours and kilometres, height gain, terrain, number of steps at key sites, and whether the vehicle can reach the site or there is a walk from a car park.
• Ask about the pace of the group, not only the distance. Tours that move every day involve early starts and luggage handling that do not appear in the grading.
• Ask what happens if you cannot do an activity: is there a vehicle option, a rest at the hotel, or is the day unavoidable?
• For any mobility limitation, contact the operator before booking. Many can adapt a private tour but not a group departure, and it is better to know in advance.
• Discuss the grade with your doctor if you have a condition affecting stamina, balance or joints.

Pregnancy and pre-existing conditions

Anyone who is pregnant, or who has a condition such as diabetes, heart or lung disease, a weakened immune system or a recent operation, should have a specific conversation with a doctor about the itinerary, not just the destination. Some activities on tours (altitude, diving, long overland days, remote areas far from care) may be advised against, and some vaccinations may be affected. Insurance is the second conversation: policies commonly require conditions to be declared, and travelling against medical advice can void cover. Get the doctor's view in writing if the insurer asks for it.

The six-week timeline

• Week 6: book the travel clinic, and a doctor's appointment if you have a condition. Send the itinerary to both.
• Week 5: attend the clinic. Start any course that needs several weeks. Ask about food, water and altitude for the specific route.
• Week 4: request prescriptions in the quantity needed and any doctor's letters. Check destination rules on carrying medicines.
• Week 3: confirm allergies, mobility needs and medical conditions with the operator in writing. Buy travel insurance if not already in place, declaring conditions.
• Week 2: assemble medication, prescription copies, allergy cards and insurer details. Check that any certificates are dated correctly.
• Week 1: pack medication in hand luggage. Save the insurer's assistance line and the operator's emergency number offline.

Everything above is general information. A travel clinic or your own doctor is the right place for decisions about vaccinations, medication and fitness to travel, and for advice on your own circumstances.
