Make sure you are up-to-date on routine vaccines before every trip, such as:

• measles-mumps-rubella (MMR) vaccine
• diphtheria-tetanus-pertussis vaccine
• varicella (chickenpox) vaccine
• influenza vaccine

Ciguatera fish poisoning

Ciguatera is a poisoning resulting from eating certain fish in particular regions in the Indian Ocean, Pacific Ocean, and the Caribbean. Mackerel caught around mid-October in Australia are a classic cause of this condition.

Hookworm (Cutanea Larva Migrans)

Hookworm is a parasite that can infect humans in countries with poor sanitation and a warm, moist climate. Hookworm larvae penetrate through intact skin (such as walking with bare feet), and can go on to cause severe gastrointestinal and skin infections.

You should avoid walking barefoot in areas where there may be contaminated soil. In addition, don’t touch soil or sand with your bare hands.

Travellers diarrhoea

Traveller’s diarrhoea affects roughly 20-50% of overseas travellers. It is caused by ingesting contaminated food or water. The bacteria that trigger the illness may appear harmless to the local population, usually because they have developed immunity to them. Symptoms include abdominal bloating, cramps, nausea, fevers and diarrhoea.

Tips to prevent traveller’s diarrhoea:

• Avoid contaminated foods such as raw or peeled vegetables, undercooked meats, unpasteurised dairy products and food from street vendors.
• Avoid drinking or brushing your teeth with tap water
• Buy bottled water to drink
• Boil tap water for at least 5 minutes before drinking it
• Avoid drinks that contain ice
• Avoid using tap water to wash your fruit and vegetables
• Wash your hands and eat at reputable restaurants.

Zika

Zika virus is a mild febrile illness, spread via the bite of an infected mosquito or by having sex with an infected person. Studies have shown that Zika virus infection in a pregnant woman can be transmitted to the baby, causing congenital problems such as microcephaly.

The best way to prevent Zika is to protect yourself from mosquito bites. Pregnant women should consider deferring travel to high risk countries

Make sure you are up-to-date on routine vaccines before every trip, such as:

• measles-mumps-rubella (MMR) vaccine
• diphtheria-tetanus-pertussis vaccine
• varicella (chickenpox) vaccine
• influenza vaccine

Lyme disease

Lyme disease is a tick-borne illness caused by the bacterium Borrelia burgdorferi. It is spread by ticks

Prevention includes measures to prevent tick bites such as wearing long pants and using repellents like DEET.

Tick-borne encephalitis (Rickettsia)

Tickborne encephalitis is a viral infection of the central nervous system transmitted by tick bites. It most commonly affects people who visit or work in forests or fields. Infection also can be acquired by consuming unpasteurised dairy products from infected cows, goats or sheep.

An effective vaccine is available but can only be obtained via a Special Access Scheme. It is only recommended for travellers who plan to spend extended periods in affected areas, especially if extensive rural exposure is planned during warmer months

You should avoid mosquito bites to prevent malaria.

You may need to take prescription medicine before, during, and after your trip to prevent malaria, depending on your travel plans, such as where you are going, when you are traveling, and if you are spending a lot of time outdoors or sleeping outside. Effective options would include doxycycline, atovaquone/proguanil or mefloquine.

Malaria is present throughout the year in all areas except for the southern province of Rennell and Bellona, the eastern province of Temotu, and the outer islands of Tikopia, Anuta and Fatutaka.

Make sure you are up-to-date on routine vaccines before every trip, such as:

• measles-mumps-rubella (MMR) vaccine
• diphtheria-tetanus-pertussis vaccine
• varicella (chickenpox) vaccine
• influenza vaccine

Dengue

Dengue fever is an infection transmitted by mosquitoes in tropical and subtropical areas of the world. There is no vaccine to prevent infection, so you should protect yourself from mosquito bites at all times in dengue areas.

Ciguatera fish poisoning

Ciguatera is a poisoning resulting from eating certain fish in particular regions in the Indian Ocean, Pacific Ocean, and the Caribbean. Mackerel caught around mid-October in Australia are a classic cause of this condition.

Lymphatic filariasis

Lymphatic filariasis or elephantiasis is a tropical disease caused by parasitic worms spread by infected mosquitoes. Although most cases are symptomless, the disease can occasionally cause severe swelling in the legs, arms and genitals.

Melioidosis

Melioidosis is an infectious disease caused by a bacterium (Burkholderia pseudomallei) which lives in soil and water. It is an important public health issue in parts of Vietnam and northern Australia.

In endemic areas, people (rice-paddy farmers in particular) are warned to avoid contact with soil, mud, and surface water where possible

Soil-transmitted helminths

Wearing enclosed footwear in undeveloped areas is important to prevent hookworm. Hookworms penetrate through intact skin such as walking with bare feet, and can cause severe gastrointestinal and skin infections.

Tuberculosis

Tuberculosis is a disease caused by infection with the bacteria Mycobacterium tuberculosis. Tuberculosis can damage a person’s lungs or other parts of the body and cause serious illness.

• Avoid exposure to people who have active tuberculosis.
• Only consume pasteurized milk products.
• Travellers at higher risk should be tested for tuberculosis upon their return home.
• There is a vaccine available which confers partial protection. Speak to your doctor to determine if this is recommended.

Malaria is present throughout the year in all areas of Somalia.

Rabies can be found in dogs, bats, and other mammals in this country, but it is not a major risk to most travellers. The vaccine is only recommended for these groups:

• Travellers involved in outdoor and other activities in remote areas that put them at risk for animal bites (such as adventure travel and caving).
• People who will be working with or around animals (such as veterinarians, wildlife professionals, and researchers).
• People who are taking long trips or moving to remote areas

Make sure you are up-to-date on routine vaccines before every trip, such as:

• measles-mumps-rubella (MMR) vaccine
• diphtheria-tetanus-pertussis vaccine
• varicella (chickenpox) vaccine
• influenza vaccine

Leishmaniasis

Leishmaniasis is a parasitic disease caused by a parasite transmitted by sand flies. Roughly 10 million people in the world are currently infected. Its most serious form is known as kala-azar, which is fatal in 95% of cases.

You can reduce your risk of catching leishmaniasis by sleeping under nets treated with insecticide. Other measures include spraying insecticides to kill sandflies.

Schistosomiasis

Bilharzia (schistosomiasis) is a common, serious infection caused by a parasite found in rivers, streams and lakes in sub-Saharan Africa, Asia and South America. The parasite infects people by penetrating their skin then developing in the person’s blood stream.

No vaccine is available. To avoid bilharzia:

• avoid paddling, swimming and washing in fresh water – only swim in the sea or chlorinated swimming pools
• take waterproof trousers and boots with you if there’s a chance you’ll need to cross a stream or river
• boil or filter water before drinking – as the parasites could burrow into your lips or mouth if you drink contaminated water
• avoid medicines sold locally that are advertised to treat or prevent schistosomiasis – these are often either fake, substandard, ineffective or not given at the correct dosage
• don’t rely on assurances from hotels, tourist boards or similar that a particular stretch of water is safe – there have been reports of some organisations downplaying the risks
