In this focus, all epidemiological factors that can contribute to trypanosomes transmission are present. To update our knowledge on the current risks of Human and Animal African trypanosomiases, different trypanosome species were identified in midguts of tsetse flies captured in the Bafia focus. [...] The present study was designed to update our knowledge on the current risks of HAT and AAT in the “silent” HAT focus of Bafia of Cameroon by providing entomological data as well as trypanosome infections in tsetse flies captured in villages of this focus. Thereafter, the distribution of tsetse flies and trypanosome infections was performed in order to localize sites and villages where transmission of trypanosomes is still active and where the control operation must be implemented.
Conclusion This study has shown that animal trypanosomes remain an important problem in this region. Meanwhile, it is very likely that Human African Trypanosomiasis (HAT) does not seem anymore to be a public health problem in this focus. The generated maps enabled us to define high risk transmission areas for African Animal trypanosomiasis (AAT), and where disease control must be focused in order to improve animal health as well as the quantity of animal proteins.
