  abstract = {{B}ackground: {H}uman {A}frican {T}rypanosomiasis ({HAT}) remains a public health problem in many poor countries. {D}ue to lack of financial resources in these countries, cost-effective strategies are needed for efficient control of this scourge, especially the tsetse vector. {I}t was shown that perennial water sources maintain a favourable biotope for tsetse flies and thus the transmission dynamics of sleeping sickness. {T}he present paper aimed at assessing the transmission dynamics of {HAT} in a forest environment where the hydrographic network is important. {M}ethods: {T}wo entomological surveys were carried out in {J}uly 2009 and {M}arch 2010 in the {B}ipindi sleeping sickness focus of the {S}outh {R}egion of {C}ameroon. {E}ntomological and parasitological data were collected during both trapping periods (including the climate variations throughout a year) and compared to each other. {T}he level of risk for transmission of the disease during each trapping period was also evaluated at the trap level and materialised on the map of the {B}ipindi focus. {R}esults: {G}lossina palpalis palpalis was the most prevalent tsetse fly species captured in this focus. {T}he overall densities of tsetse flies as well as the risk for transmission of {HAT} in the {B}ipindi focus were significantly higher in {J}uly than in {M}arch. {A}t the trap level, we observed that these parameters were almost constant, whatever the trapping period, when the biotope included perennial water sources. {C}onclusions: {T}his study shows that the spatial distribution of traps, as well as the temporal climatic variations might influence entomological and parasitological parameters of {HAT} and that the presence of perennial water sources in biotopes would favour the development of tsetse flies and thus the transmission of sleeping sickness. {T}hese factors should, therefore, be taken into account in order to provide more efficient vector control.},
