Guide to Common Travel Health Risks
One of the biggest holiday disruptors is food- and water-borne illness, especially traveller’s diarrhoea. Even healthy travellers can be affected, as hygiene standards vary widely between destinations. Thinking ahead about travel health can make a huge difference to your trip. Illness is often caused by contaminated water, salads, ice, buffets or undercooked food, and once unwell, plans can change quickly.
Mosquito-borne diseases like dengue, malaria and Japanese encephalitis are another key concern, particularly in rural or forested parts of Southeast Asia. Preventive measures matter, repellents, long sleeves, and when appropriate, medication or vaccines depending on your itinerary.
Some illnesses are vaccine-preventable. Hepatitis A, Typhoid, Tetanus and Influenza are among the vaccines commonly recommended for Southeast Asian travel. Suitability depends on your destination, trip duration and style, whether you’re on a food-focused city holiday, a remote trek, or a relaxed resort break.
Rabies exposure is rare but serious. Bites or scratches from dogs, monkeys or bats require urgent medical care, and post-exposure treatment isn’t always readily available in remote regions. Being prepared avoids unnecessary worry.
Altitude, extreme climates and remote terrain bring unique challenges too. While we’ll cover altitude sickness in a separate blog, travel to high-altitude regions often requires early planning and the right advice.
When should you see a doctor before travelling?
A travel consult is helpful if you’re travelling with young children, if someone in your family has a medical condition, or if your itinerary includes rural areas, trekking, or places where healthcare access may be limited. It’s also worthwhile if you aren’t sure about your vaccination status or haven’t updated boosters in a while.
During your visit, Dr Cameron will review your health history, destination and travel style, recommend vaccinations if needed, help plan preventive strategies for jet lag or motion sickness, and advise what to carry in a travel medical kit, things like oral rehydration salts, basic medication, and prescriptions you may need overseas.
“Good travel health isn’t about being anxious, it’s about being prepared. A short conversation before your trip can prevent a lot of unnecessary stress while you’re overseas.”
In some cases, antibiotics may be prescribed for severe traveller’s diarrhoea – this depends on the destination, risk profile and patient suitability.

Where to check travel health alerts & outbreaks?
