The main health risks
Prevention of illnesses transmitted by insect bites:
This parasitic disease, which is transmitted by mosquito bites, requires the use of individual protective measures (sprays, creams, plug-in repellents, mosquito nets, etc.). To these measures one may add a bespoke cocktail of drugs that is suited to each individual.
Vaccination against yellow fever is mandatory (should be done in an approved centre). The updating of the diphtheria-tetanus-polio vaccine is recommended.
