Between October 8th and November 11th, 2021 86 cases of dengue fever infections were registered in the district of Richard Tol, Saint Lois region. So far, Dengue virus serotypes 1 and 3 (DENV 1 and DENV 3) have been reported.
Dengue is endemic in Africa. The exact extent of its spread on the African continent is unclear, as a diagnosis is often not made and epidemiological surveillance is poor.
Consequences for travelers
Protect yourself optimally around the clock (24/7) against mosquitoes (see factsheet mosquito and tick bite protection): during the day against dengue, chikungunya, Zika and other viruses, at dusk and at night against malaria. If you should have a fever: take medication containing the ingredient paracetamol and make sure you drink enough fluids. Do not take any medication containing the ingredient acetylsalicylic acid (e.g. Aspirin®), as this can increase the bleeding tendency in the event of a dengue infection (see also factsheet dengue). If you have visited a malaria area and have a fever >37.5 °C, you should always exclude malaria by taking a blood smear on the spot. Visit a medical facility for this (see also factsheet malaria).
