Gabon

Malaria is a parasitic infection spread through the bite of infected mosquitoes, which can cause fever, chills, headache, muscle aches, and fatigue. Without prompt treatment, malaria can become severe and life-threatening, particularly when caused by Plasmodium falciparum, the most dangerous malaria parasite.

Malaria risk exists throughout Gabon year-round, including in Libreville and rural areas. Mosquitoes that transmit malaria are most active from dusk until dawn. Travellers visiting Gabon should discuss antimalarial medication with a travel doctor before departure, as the most suitable option depends on itinerary, medical history, and duration of travel.

Medication should be obtained before leaving Australia and taken exactly as prescribed. In addition, travellers should use mosquito bite prevention measures throughout their stay, including insect repellent, protective clothing, and insect-proof accommodation.

Any fever developing during travel or within one year of returning from Gabon requires urgent medical assessment. Always tell the treating doctor about your recent travel history, as malaria can progress quickly if not recognised.

African trypanosomiasis, also known as sleeping sickness, is a parasitic infection transmitted by infected tsetse flies. These flies are found mainly in rural and forested areas and can transmit infection through their bite.

The risk to travellers staying in Libreville is very low, but exposure is possible for those undertaking rainforest trekking, wildlife activities, or spending extended periods in rural environments. Tsetse flies are attracted to moving vehicles and dark colours, and ordinary mosquito repellents do not reliably protect against them.

There is no vaccine or preventive medication available. Travellers can reduce risk by wearing long-sleeved, neutral-coloured clothing, avoiding areas with dense vegetation where possible, and checking for insect bites after outdoor activities.

Early symptoms may include fever, headaches, swollen lymph nodes, or a painful bite site. Later stages can involve neurological symptoms and disruption of sleep patterns. Any unexplained fever or neurological symptoms after rural travel in Gabon should prompt medical review with your travel history discussed.

Gastroenteritis is a common risk in Gabon, usually caused by bacteria, viruses, or parasites acquired through contaminated food, water, or poor hand hygiene.

Symptoms may include diarrhoea, nausea, vomiting, stomach cramps, and loss of appetite, often beginning within a few days of exposure. Most mild cases improve with rest, fluid replacement, and oral rehydration solutions.

Prevention relies on consistent food and water precautions throughout the trip. Drink bottled or treated water, avoid raw or undercooked foods, choose freshly prepared meals served hot, and practise regular hand hygiene.

Medical advice should be sought if symptoms are severe, persistent, associated with dehydration, bloody diarrhoea, or high fever. Healthcare access may be limited outside Libreville, making prevention particularly important.

Dengue, Chikungunya, and Zika are viral infections spread by Aedes mosquitoes, which bite mainly during daylight hours, particularly around early morning and late afternoon.

Dengue commonly causes sudden fever, headache, fatigue, and significant muscle and joint pain. Some cases can progress to severe illness requiring medical care.

Chikungunya produces a similar feverish illness, with prominent joint pain that may persist for weeks or months after infection.

Zika infection is often mild or asymptomatic but is particularly important for people who are pregnant or planning pregnancy, as infection during pregnancy can affect the developing fetus. Zika can also be transmitted sexually.

There are no specific antiviral treatments for dengue, chikungunya, or Zika , so preventing mosquito bites is the most effective protection. Use insect repellent containing DEET or picaridin, wear protective clothing, and stay in accommodation with appropriate mosquito barriers where possible.

Gabon occasionally experiences Ebola outbreaks. Outside outbreak periods, the risk to travellers is low.

Ebola virus disease is a rare but serious infection that can cause severe illness, bleeding, and organ failure. It spreads through close contact with infected people, healthcare exposure, or participation in traditional burial practices involving someone who died from Ebola. Casual contact with people in everyday settings is considered much lower risk.

Travellers should avoid contact with sick individuals, avoid handling dead animals, and practise careful hand hygiene. Those visiting healthcare facilities or working in medical settings should seek specific advice before travel.

Mpox is a viral infection that can spread in Gabon through close contact with an infected person, including contact with skin lesions, bodily fluids, contaminated materials, or respiratory secretions during prolonged close interaction. Some animal-to-human transmission can also occur.

Symptoms usually include fever, fatigue, swollen lymph nodes, and a characteristic rash or skin lesions that may be painful. Most cases improve with supportive care, although some people can develop more significant illness.

Travellers can reduce their risk by avoiding close physical contact with people who are unwell or have unexplained skin lesions, avoiding contact with wild animals, and practising good hand hygiene. Travellers at higher risk should discuss mpox vaccination eligibility with a healthcare professional before departure.

Schistosomiasis (also known as bilharzia) is a parasitic infection acquired through contact with contaminated freshwater. The parasite is released by infected freshwater snails and can penetrate intact skin during swimming, wading, or bathing in rivers, lakes, and slow-moving streams.

Freshwater exposure should be avoided throughout Gabon, particularly during rainforest travel and outdoor activities. There is no vaccine or medication that prevents infection before exposure.

Travellers who have had freshwater contact should discuss testing after returning to Australia, even if they feel well, as treatment is available and early diagnosis can prevent long-term complications.

Tuberculosis (TB) is a bacterial infection spread through the air from an infected person with active disease. It affects the lungs and may cause a persistent cough, fever, night sweats, and unexplained weight loss.

The risk to most short-term tourists is low, but exposure risk increases for travellers spending prolonged periods in local communities, healthcare facilities, prisons, or other crowded environments.

Travellers with extended stays or higher-risk activities should discuss TB screening with their travel doctor before and after travel. Any persistent cough, fever, or unexplained weight loss after returning from Gabon should be medically assessed with your travel history disclosed.
