  • This data set describes the prevalence of trypanosomes and Sodalis glossinidius, and host blood meal analysis from tsetse flies (Glossina morsitans morsitans) captured during two intensive surveys in Mambwe District, Eastern Province, Zambia in 2013. The Luangwa Valley in Zambia is an old focus of human African trypanosomiasis (HAT, Trypanosoma brucei rhodesiense) and sporadic outbreaks have continued to occur in the human population. In recent years there has been an influx of people migrating from the densely populated plateau region resulting in a significant change in land-use in the study area, potentially influencing tsetse dynamics and the epidemiology of HAT. This data set was collected to monitor infection rates of trypanosomes and Sodalis glossinidius in Glossina morsitans morsitans tsetse flies in the area so as to assess the risk posed to both human and livestock populations. In addition, feeding patterns of tsetse were investigated through analysis of blood meals. This work was part of a wider research project, the Dynamic Drivers of Disease in Africa Consortium (DDDAC) and contributed to the Zambia trypanosomiasis case study. The research was funded by NERC project no NE/J000701/1 with support from the Ecosystem Services for Poverty Alleviation Programme (ESPA).

  • This resource contains anonymised interviews with community members in Chundu Ward, Hurungwe District, Zimbabwe, conducted to further our understanding of how the local community interacts with tsetse. Semi-structured interviews were conducted with key informants in 2012 to 2013 to investigate livelihood strategies including hunting, livestock keeping and cultivation, and how they influenced the risk of contracting trypanosomiasis. Human African trypanosomiasis (HAT) occurs sporadically within the Zambezi Valley in Zimbabwe and is transmitted by the tsetse fly (Glossina morsitans morsitans and Glossina pallidipes). African animal trypanosomiasis (AAT) is more prevalent and places significant constraints on livestock keeping. Approaches taken by local people to control or manage the disease were also investigated during the interviews. This research was part of a wider research project, the Dynamic Drivers of Disease in Africa Consortium (DDDAC) and these interviews contributed to this consortium. The research was funded by NERC project no NE/J000701/1 with support from the Ecosystem Services for Poverty Alleviation Programme (ESPA).

  • The data set includes the results of a laboratory analysis in 2016, investigating the presence of trypanosomes and prevalence of tsetse endosymbionts in tsetse flies. The tsetse flies were sampled in Hurungwe District, Mashonaland West Province, Zimbabwe, from February 2014 to November 2014. Flies were sampled using a combination of Epsilon traps and fly rounds, both established techniques for sampling tsetse. Tsetse were stored prior to laboratory analysis using Polymerase chain reaction (PCR) techniques in 2016. The data include two species of tsetse, Glossina pallidipes and Glossina morsitans morsitans. Trypanosome species investigated include Trypanosoma brucei s.l., T. b. rhodesiense, T. vivax, T. congolense, T. simiae, T.simiae (Tsavo) and T. godfreyi. Endosymbionts included in the study were Sodalis glossinidius and Wolbachia spp. Hurungwe District is the only sleeping sickness focus in Zimbabwe and an increase in cases had been detected in years preceding this study. The objective of the study was to investigate the trypanosome species present in the tsetse population and their association with tsetse endosymbionts. This study was conducted as part of research into the relationship between trypanosomiasis, well-being and ecosystems by the Dynamic Drivers of Disease in Africa Consortium (DDDAC). The research was funded by NERC with support from the Ecosystem Services for Poverty Alleviation Programme (ESPA).

  • This resource contains tsetse fly count data recorded during two intensive surveys in Mambwe District, Eastern Province, Zambia in 2013. Tsetse sampling was conducted along a 60 kilometre transect from the plateau region on the eastern side of the Luangwa Valley to the floor of the valley, near Mfuwe Airport. Tsetse flies were sampled using black screen fly rounds. The first survey was conducted in May and June (cold, dry season) and the second survey in November (hot dry season). The Luangwa Valley in Zambia is an old focus of human sleeping sickness (Trypanosoma brucei rhodesiense) and sporadic outbreaks have occurred in the human population. In recent years there has been an influx of people migrating from the densely populated plateau region resulting in a significant change in land-use in the study area, potentially influencing the distribution and density of tsetse. This work was part of a wider research project, the Dynamic Drivers of Disease in Africa Consortium (DDDAC) and contributed to the Zambia trypanosomiasis case study. The research was funded by NERC project no NE/J000701/1 with support from the Ecosystem Services for Poverty Alleviation Programme (ESPA).
