“…L'étude de la structure par groupes d'âge des échantillons de populations prélevés dans diverses parties de l'écosystème forestier montre que les communautés de G. palpalis vivant dans les plantations ont un potentiel de transmission des trypa nosomes à l'homme plus grand que celui des communautés vivant dans les autres parties de l'écosystème (Challier et Gouteux, 1980). La structure des populations de glossines varie également avec l'âge des plantations de caféiers.…”

“…Thus, human populations and, to a certain extent, domestic animals are important factors affecting the distribution of these vectors [11]. They are found widespread in all components of the ecosystem in infested areas, including forest, "interstitial savannas", coffee and cocoa plantations, tracks and villages [12]. This wide and close distribution of the vector to human beings (species of palpalis group are known to easily colonized anthropics habitats), combined with massive immigration of populations (potential human reservoir of parasites) from rural areas to towns has brought up a new epidemiological feature of the disease: suburban and urban sleeping sickness foci.…”

Sub-Saharan countries are facing a demographic growth of 3% per year. That increase of the population in number, associated with climate changes, has deeply modified environmental landscape and affected biodiversity. The distribution of tsetse flies or Glossina, vector of sleeping sickness, has been considerably modified over time. Species of morsitans group (Glossina subgenus) had disappeared from some areas, while those of palpalis group (Nemorhina subgenus) developed and adaptation in Human habitats with peridomestic behaviors. The great capacity of these species to adapt in suburban and urban areas as soon as microclimatic conditions and host availability are met has brought up a new epidemiological context of the disease: suburban and urban foci. We are reviewing that epidemiological feature in order to draw attention to that particular aspect which may impede the progress of disease elimination in sight in many T. b. gambiense sleeping sickness foci.

“…Knowing that most of the time the tsetse flies are used to stay, just after their blood meal, besides the place where they fed (Challier and Gouteux, 1980), we can consider that the number of blood meals is probably under-estimated. For LRS, among 2568 tsetse flies captured, 248 midguts (9.7%) containing blood were able to be analysed (CI 95%, 3.9-15.5), while 268 blood meals (13.5%) among 1991 tsetse flies that were captured (CI 95%, 6.8-20.2) were able to be analysed for MDS (Fig.…”

Vector control is an effective and cost-efficient way to disrupt the transmission of human African trypanosomosis (HAT); it has nonetheless been little used to date in the disease's foci. With the aim to target trapping more precisely and to develop an optimized vector control system, a transmission risk index was used in the HAT focus of Bipindi, in the forest zone of southern Cameroon. The authors used a simplified version of the index originally developed by Laveissière et al. in 1994. The calculation of this new index only requires knowledge of the proportion of teneral flies and the proportion of flies with human blood meals in samples caught in different biotopes. This makes it possible to identify the biotopes displaying permanent risk, such as riverbanks, as well as biotopes displaying seasonal risk, such as marshy hollows and encampmemts. In the villages, the domestic pig, with 49% of the identified blood meals, is the favorite host of the tsetse flies during the short rainy season. The proportion of blood meals taken on human beings does not significantly increase when domestic pigs are absent. Game animals, contributing to 46% and 64% of the blood meals during the short rainy season and the long dry season, respectively, are also favored as feeding hosts in this particular HAT focus.
