Angola

Malaria represents the most significant infectious disease risk for travellers to Angola. Risk due predominantly to Plasmodium falciparum exists throughout the year across the entire country.

The parasite infects red blood cells and the liver, producing a fever, along with chills, headache, nausea, vomiting, and muscle aches. Symptoms typically appear between seven days and four weeks after an infected mosquito bite. Severe malaria can progress rapidly and may be fatal without prompt treatment.

A travel doctor should be consulted regarding appropriate antimalarial medication for the specific itinerary, and any fever occurring during or after travel to Angola should be assessed urgently, with travel history disclosed to the treating doctor.

Human African trypanosomiasis (HAT), also known as African sleeping sickness, is a parasitic infection transmitted by the bite of infected tsetse flies. Although the disease is now uncommon in most travellers, cases continue to occur in some parts of sub-Saharan Africa, particularly in rural and remote areas.

Early symptoms may include fever, headache, fatigue, muscle and joint pains, and swollen lymph nodes. If left untreated, the parasite can invade the central nervous system, leading to sleep disturbances, behavioural changes, neurological symptoms, and, in some cases, death.

Travellers visiting affected regions should take measures to avoid tsetse fly bites, including wearing long-sleeved, neutral-coloured clothing and using insect avoidance strategies. Any unexplained fever or illness occurring during or after travel to a risk area should prompt medical assessment, with travel history disclosed to the treating doctor.

Gastroenteritis is a common illness among travellers to Angola and is usually caused by bacteria, viruses, or parasites acquired through contaminated food, water, or poor hand hygiene. Symptoms often develop within hours to several days after exposure and commonly include diarrhoea, abdominal cramps, nausea, vomiting, and sometimes fever. While most cases are mild and self limiting, significant fluid loss can lead to dehydration, particularly in young children, older adults, and travellers spending time in Angola’s hot climate.

Treatment is mainly supportive, with adequate fluid replacement being the priority. Oral rehydration solutions are recommended as they replace both water and essential electrolytes lost through diarrhoea and vomiting. Travellers should seek medical attention if symptoms are severe, persist beyond several days, involve blood in the stool, are associated with high fever, or if they are unable to maintain hydration.

Given that medical facilities and access to advanced care can be variable outside Luanda, careful attention to food choices, drinking safe water, and good hand hygiene are important preventative measures during travel.

Both dengue and chikungunya are present in Angola, transmitted by mosquitoes active throughout the day. Insect borne diseases and dengue fever represent a recognised threat in the country, producing symptoms including fever, severe headache, and significant joint and muscle pain. Chikungunya is typically distinguished by prolonged joint pain that may persist for weeks following the initial illness. There is no specific treatment for either infection, making consistent mosquito bite prevention throughout the day the most effective protective measure available to travellers.

Zika virus is a mosquito-borne infection spread mainly by Aedes mosquitoes, which bite during the day. It occurs in Angola and is often asymptomatic, but when symptoms do occur they are usually mild and include fever, rash, conjunctivitis, joint pain, and headache, typically lasting up to a week.

The main concern is during pregnancy, as infection can be passed to the fetus and may cause serious abnormalities in the baby. Zika can also be transmitted sexually, so precautions are advised after travel.

There is no vaccine or specific treatment. Prevention focuses on avoiding mosquito bites using repellent, long clothing, and screened or air-conditioned accommodation. Pregnant travellers should seek pre-travel advice at the early planning stages, before contemplating visiting affected areas.

Rabies is a significant and ongoing health concern in Angola. The disease is common in this destination and is carried by dogs and some wildlife, including bats. Rabies is considered a risk and has been reported in domestic animals across the country, with bats also capable of carrying rabies like viruses.

Travellers should avoid all contact with domestic and wild animals throughout their visit, including stray dogs and bats, even where an animal appears healthy or approachable. Treatment to prevent rabies may be limited or unavailable in Angola, and travellers requiring post exposure treatment may need to travel to another location to receive it. Pre-exposure rabies vaccination is recommended for travellers at increased risk, including those working or living in remote or rural areas without easy access to medical facilities, longer stay travellers, those undertaking activities such as trekking, cycling, or running, and those working with or regularly handling animals.

Any bite, scratch, or lick to broken skin from an animal, including bats, requires medical attention regardless of prior vaccination status. Wounds should be thoroughly cleansed and prompt medical assessment sought, even where the wound appears minor. A full pre-departure vaccination course simplifies subsequent post-exposure treatment and reduces dependence on rabies immunoglobulin, a product that remains in limited global supply.

Schistosomiasis (also known as bilharzia) is a parasitic infection that can be acquired through contact with freshwater contaminated by larval parasites released by infected snails. Risk exists in many parts of Africa, including Angola, particularly in lakes, rivers, streams, and other untreated freshwater sources.

The parasites penetrate the skin and can migrate through the body, affecting organs such as the intestines, liver, and urinary tract. Early symptoms may include an itchy rash, fever, fatigue, muscle aches, and abdominal discomfort, although many infections cause no immediate symptoms. Untreated infection can lead to long-term complications affecting the urinary and gastrointestinal systems.

Travellers should avoid swimming, wading, or bathing in untreated freshwater and seek advice from a travel doctor before departure if freshwater exposure is anticipated. Anyone who has had freshwater contact in a risk area should discuss the need for screening after travel, even if they remain well.

Tuberculosis (TB) is a bacterial infection caused by Mycobacterium tuberculosis. It is spread through the air when an infected person coughs, speaks, or sings, primarily affecting the lungs and producing persistent cough, fever, night sweats, and unexplained weight loss.

The risk to short term travellers staying in well resourced accommodation is generally low. Travellers undertaking an extended stay, volunteer work, or close ongoing contact with local communities should discuss TB screening with their travel doctor before and after travel. A persistent cough or unexplained fever following travel to Angola should be reported to a general practitioner along with relevant travel history.
