In this region, the immature stages of both species develop in stagnant water found mainly in peri-domestic containers such as used tires and discarded tanks. albopictus can be found together in the same location and often share the same larval habitatsġ5. Previous studies in Central Africa showed that bothĪe. aegypti in sympatric areas has been shown to result from the higher mating competitiveness ofġ7. aegypti in human-domesticated environmentĪe. albopictus was reported for the first time in Central Africa in early 2000ġ2 and is currently present in almost all central African countriesġ3, where it tends to supplant the indigenous speciesĪe. This rapid global spread was caused mainly by sales and distribution of used tires across the worldġ1 coupled with the ecological plasticity of the species, enabling its adaptation to various environmentsĪe. albopictus is a native of South East Asia, it has now invaded all the five continents during the past 30–40 yearsġ0. aegypti collected in central Africa matchĪe. aegypti aegypti is light-colored with white abdominal scales and is found in human-dominated habitats primarily outside Africa. aegypti formosus, is a dark colored mosquito confined to African forests whileĪe. aegypti aegypti, were formally identified by Mattingly in 1957Īe. albopictus, are found in sub-Saharan Africa, whereĪe. Other potential modes of zika virus transmission to humans have been evoked notably via sexual intercourse or via blood donorĪe. The enzootic cycle occurs in the sylvan environment, involving non-human primates and wild mosquitoes, while urban epidemic cycle occurs in urban environments, implicating human beings and urban mosquitoes such asĪe. Indeed, two distinct ecological cycles, enzootic and urban epidemic cycles, have been well documentedĦ. These viruses are transmitted to vertebrates, including humans, by the bites of infected mosquitoes that share the same ecological niche as the host organism. Arthropod-borne viral diseases such as dengue, zika and chikungunya have emerged or re-emerged in several countries of the world during the past decades
