Senegal is one of West Africa’s most visited countries; it is considered one of the most stable democracies in Africa, which is probably why it is more popular than it’s neighbouring countries. Senegal offers the hustle and bustle of Dakar, the sand dunes of the Lompul Desert, the clear waters of the Casamance and tropical backwaters of the Sine-Saloum Delta. Unfortunately, a tropical environment comes with tropical diseases, especially ones that fly!

Sleeping sickness, also known as “human African trypanosomiasis”, is caused by the tsetse fly, which is native to the African continent and generally active during the day. If an infected tsetse fly, which is carrying the parasite, bites you, it can cause acute trypanosomiasis. Sleeping sickness infects the brain causing confusion, disturbed sleep (hence the name) and can be fatal if not treated.
Malaria is prevalent throughout the whole of West Africa, including Senegal. It is spread by the bite of an infected Anopheles mosquito. Generally, these mosquitos bite most often during dusk til dawn. All travellers to Senegal should take anti-malarial medication and take preventative measures against mosquitoes.
Yellow Fever is a virus spread by the Aedes mosquito, that is most active from dawn till dusk. Catching Yellow Fever can be fatal but can be prevented by vaccination. The vaccination gives a lifetime of protection, however, it is not suitable for everyone and a comprehensive risk assessment should be sought from a travel clinic. Additionally, there is a requirement to be in possession of a valid Yellow Fever certificate when entering Senegal from another infected country, especially those who plan onwards travel to Gambia or Guinea-Bissau.
Zika Virus is spread by the Aedes mosquito which commonly bites during the day in urban settings, such as Dakar and St Louis. The majority of people who are infected with Zika virus have no symptoms, but if contracted during pregnancy or close to conception it can cause Congenital Zika Syndrome. Currently, there is no vaccination nor cure for Zika virus infection and strict precautions against mosquitoes should be taken.
Best prevention to banish those bugs?
- Wear long loose clothing and cover-up. If the insects can’t bite you, they can’t transmit their diseases to you.
- Use a minimum of 50% DEET spray on any exposed areas of skin and reapply regularly
- Sleep under a mosquito net
- Treat clothes with permethrin
- Ensure you receive a travel consultation prior to departure to receive the appropriate pre-travel vaccinations and medications against malaria and Yellow Fever
- You can purchase one of our Ultimate Bug Kits to help protect yourself
