Nasty travel diseases

Travel disease

We all know getting sick can ruin your holiday. And it’s safe to say that being holed up in the hotel room whilst everyone else is out enjoying the poolside bar isn’t how you imagined your tropical getaway playing out.

But a bout of the sniffles isn’t the worst of it - serious diseases like dengue and even rabies still pose a risk to unwary travellers.

Thankfully, there are some simple ways you can avoid illnesses like these overseas. We’re here to shed light on six nasty travel diseases so you can steer clear of a holiday nightmare.

1. Zika virus

Zika is transmitted by mosquitoes and often doesn’t have any symptoms. In some cases, the virus causes fever, joint pain and headaches, but generally doesn’t require hospitalisation.

Because Zika has been linked to serious birth defects in newborns, the WHO advises pregnant women to take special precautions.

Countries in Central and South America, and parts of the Pacific Islands have seen the most reported cases of the Zika virus. While we love hearing about exotic adventures in unique places like these, it’s important to stay up-to-date with official health warnings on the Safe Travel government website.

If you book a holiday to a destination that already has a ‘Do not travel’ or ‘Reconsider your need to travel’ advisory, we’re unable to offer you cover if you need to make a claim related to that travel warning.

As with other mosquito-borne diseases, avoiding bites is the key to staying healthy. This can be easier said than done, but there are a few simple tips to remember:

  • Wear insect repellent whenever possible
  • Use a mosquito net at night
  • Cover up with loose-fitting, long sleeved clothing
  • Close windows and use air conditioning
  • Avoid standing water - mosquitos love it


2. Rabies

Not only is rabies one of the most widespread infectious diseases, it’s also one of the deadliest. In 2015, 15 people died of rabies in Bali alone. The virus is spread by the saliva of infected animals and is usually transmitted to humans by licks, bites and scratches.

The best way to avoid rabies is to avoid animals. If your trip involves a lot of time outdoors, whether that be camping or hiking, always take special care around animals no matter how docile they might appear. Stray dogs are common in the streets of many parts of Asia, and Central and South America, so even if you plan to stick to the resorts and restaurants, it’s important to keep your guard up.

If you’re visiting a high-risk area, your doctor will recommend a rabies vaccination. However, if you get bitten or scratched by an animal overseas you must seek medical treatment straight away, even if you’re vaccinated.

If you’re travelling with children, remind them to look but not touch!

3. Tuberculosis

There are nearly 1.5 million tuberculosis-related deaths around the world each year. But interestingly, not everyone infected with tuberculosis (TB) gets sick.

TB normally affects the lungs, causing coughing, tiredness, loss of appetite, fever and weight loss. Like other airborne diseases, TB is transmitted when infected people cough, sneeze and speak. A TB vaccine exists, but according to the CDC, it’s not very effective.

So how can you avoid TB? The most obvious answer is to avoid coming into contact with anyone who has active TB as it’s highly contagious. But there are also some other tips and tricks that could help:

  • Get a protein boost - too little in your diet can weaken your immune system.
  • If you’re stuck in the bar without hand sanitiser, use a dash of vodka on your hands instead.
  • Avoid alcohol before bed; it disrupts rapid eye movement sleep which is needed to stay healthy.
  • If you pass somebody coughing or sneezing, exhale slowly until you’re a good distance away.


4. Flu

Some of us may think “no big deal” when we hear the word flu. But although it may be common, it can cause serious health complications, particularly for people with existing health problems.

Nonetheless, even a fairly mild case can take the shine off your well-deserved break.

Like tuberculosis, flu is an airborne respiratory disease spread by coughing and sneezing. But unlike TB, the annual vaccination is very effective in protecting yourself against the virus.

Simple precautions like avoiding touching your face, avoiding close contacts on public transport and using antibacterial wipes and hand sanitisers will help you stay healthy.

5. Dengue fever

Severe cases of the nasty dengue fever can cause intense stomach pain, bleeding from the gums, repeated vomiting and even death. As if there weren’t already enough reasons to dislike mosquitoes!

Unlike its mosquito-borne cousin, Malaria, there is no vaccine or medication to prevent dengue. Keeping up to date with current alerts for the dengue virus and taking special care to avoid bites in high-risk areas is your best defence.

Tropical areas are typically the most at-risk of the virus, but there are also occasional outbreaks across the world.

6. Typhoid

Typhoid fever is a bacterial infection transmitted through contaminated food and water. It causes fever, stomach pains, headache and weakness. It is most common in developing countries with poor sanitation, including India, South America, Egypt and South East Asia.

As with rabies, your doctor will recommend a typhoid vaccination if you are travelling to a high-risk area. But according to the CDC, it’s only 50%-80% effective, so being selective about your food is crucial.

Tips to avoid getting sick

To reduce your risks, avoid the following foods:

  • Raw or undercooked food, including seafood and salads
  • Street food unless it has been cooked in your presence and doesn’t contain any uncooked extras
  • Unwashed fruits and vegetables - unless you can peel them, like bananas and oranges
  • Unpastuerised dairy products
  • Game meat - monkeys, bats, or other wild game

Avoiding contaminated water can be tricky, especially when ordering drinks at the bar. Make sure to ask for no ice cubes, and stick to bottled water. For adventure travellers, investing in a water-filter and water-purification tablets is a must.

What to do if you get sick

We know how upsetting it can be to fall sick overseas. Which is why all of our policies include Southern Cross Worldwide Emergency Assistance, giving you access to one of the world’s largest networks of emergency medical resources at all times.

If you require medical care or incur medical expenses overseas that are likely to exceed $2,000, you or someone acting on your behalf will need to contact Southern Cross Emergency Assistance for prior approval as soon as possible on +64 9 359 1600.

We will be able to review your claim, organise emergency evacuation if necessary, provide the hospital with a payment guarantee so you don’t have to pay up-front subject to you meeting the terms and conditions of your policy, and keep your family back home informed of your situation. Keep hold of your receipts and any doctor’s notes as we will need to see these alongside your claim.

If you need to visit a GP for a minor medical reason, you don’t need to contact Southern Cross Emergency Assistance. Instead, simply pay your account and claim.

If you need specialist treatment (including physiotherapy and chiropractic treatment) you must get a referral from a registered medical practitioner.
