VACCINES TO CONSIDER
You may be at risk for these vaccine-preventable diseases while travelling in this country. Talk to your travel health professional about which ones are right for you.
Hepatitis A is a disease of the liver spread through contaminated food and water or contact with an infected person. All those travelling to regions with a risk of hepatitis A infection should get vaccinated.
Hepatitis B is a disease of the liver spread through blood or other bodily fluids. Travellers who may be exposed (e.g., through sexual contact, medical treatment, sharing needles, tattooing, acupuncture or occupational exposure) should get vaccinated.
Seasonal influenza occurs worldwide. The flu season usually runs from November to April in the northern hemisphere, between April and October in the southern hemisphere and year round in the tropics. Influenza (flu) is caused by a virus spread from person to person when they cough or sneeze or by touching objects and surfaces that have been contaminated with the virus. Get the flu shot.
Measles is a highly contagious viral disease. It can spread quickly from person to person by direct contact and through droplets in the air.

FOOD AND WATER-BORNE DISEASES
Travellers to any destination in the world can develop travellers’ diarrhea from consuming contaminated water or food.
In some areas in Central Africa, food and water can also carry diseases like cholera, hepatitis A, schistosomiasis and typhoid. Practise safe food and water precautions while travelling in Central Africa. Remember: Boil it, cook it, peel it, or leave it!
Cholera is a risk in parts of this country. Most travellers are at very low risk.
To protect against cholera, all travellers should practise safe food and water precautions.
Travellers at higher risk of getting cholera include those:
- visiting, working or living in areas with limited access to safe food, water and proper sanitation
- visiting areas where outbreaks are occurring
Vaccination may be recommended for high-risk travellers, and should be discussed with a health care professional.
Schistosomiasis can be spread to humans through freshwater sources contaminated by blood flukes (tiny worms). The eggs of the worms can cause stomach illnesses like diarrhea and cramps or urinary problems. Risk is generally low for most travellers. Avoid swimming in freshwater sources (lakes, rivers, ponds). There is no vaccine available for schistosomiasis.
- Travellers’ diarrhea is the most common illness affecting travellers. It is spread from eating or drinking contaminated food or water.
- Risk of developing travellers’ diarrhea increases when travelling in regions with poor standards of hygiene and sanitation. Practise safe food and water precautions.
- The most important treatment for travellers’ diarrhea is rehydration (drinking lots of fluids). Carry oral rehydration salts when travelling.
Typhoid is a bacterial infection spread by contaminated food or water. Risk is higher among children, travellers going to rural areas, travellers visiting friends and relatives or those travelling for a long period of time.
Travellers visiting regions with a risk typhoid, especially those exposed to places with poor sanitation should speak to a health care professional about vaccination.
INSECTS AND ILLNESS
In some areas in Central Africa, certain insects carry and spread diseases like African trypanosomiasis (sleeping sickness), Crimean-Congo hemorrhagic fever, dengue fever, leishmaniasis, lymphatic filariasis, malaria, onchocerciasis, Rift Valley fever, West Nile virus and yellow fever.
Travellers are advised to take precautions against bites.
There is currently a risk of chikungunya in this country. Chikungunya is a virus spread through the bite of an infected mosquito. Chikungunya can cause a viral disease that typically causes fever and pain in the joints. In some cases, the joint pain can be severe and last for months or years.
Protect yourself from mosquito bites at all times. There is no vaccine available for chikungunya.
Crimean-Congo haemorrhagic fever is a viral disease that typically causes fever, bleeding under the skin, and pain. Risk is generally low for most travellers. It is spread to humans though contact with infected animal blood or bodily fluids, or from a tick bite. Protect yourself from tick bites and avoid animals. There is no vaccine available for Crimean-Congo haemorrhagic fever.
- In this country, dengue fever is a risk to travellers year-round. It is a viral disease spread to humans by mosquito bites.
- Dengue fever can cause severe flu-like symptoms. In some cases, it can lead to dengue haemorrhagic fever, which can be fatal.
- The level of risk of dengue fever changes seasonally, and varies from year to year. After a decline in reported dengue cases worldwide in 2017 and 2018, global numbers have been steeply rising again.
- Mosquitoes carrying dengue typically bite during the daytime, particularly around sunrise and sunset.
- Protect yourself from mosquito bites. There is no vaccine or medication that protects against dengue fever.
Visceral leishmaniasis (or kala azar) affects the bone marrow and internal organs. It is caused by a parasite spread through the bite of a female sandfly. It can also be transmitted by blood transfusion or sharing contaminated needles. If left untreated it can cause death. Risk is generally low for most travellers. Protect yourself from sandfly bites, which typically occur after sunset in rural and forested areas and in some urban centres. There is no vaccine or medication to protect against leishmaniasis.
Onchocerciasis (river blindness) is an eye and skin disease caused by a parasite spread through the bite of an infected female blackfly. Onchocerciasis often leads to blindness if left untreated. Risk is generally low for most travellers. Protect yourself from blackfly bites, which are most common close to fast-flowing rivers and streams. There is no vaccine available for onchocerciasis although drug treatments exist.
Zika virus infection is a risk in this country. The mosquito that spreads the virus is found here.
All travellers should protect themselves from mosquito bites and other diseases spread by insects.
- There is a risk of malaria throughout the year in the whole country.
- Malaria is a serious and occasionally fatal disease that is spread by the bite of an infected mosquito. There is no vaccine against malaria.
