African animal trypanosomosis is a vector-borne disease transmitted by tsetse flies and other vectors in 37 African countries. Affecting livestock health and welfare, the disease imposes a heavy burden on communities that rely on domestic animals for their livelihoods. In most endemic areas, trypanosomosis control relies heavily on trypanocidal drugs, which are often the only tool farmers possess to manage the problem.

Tsetse transmitted AAT causes enormous mortality, which dramatically reduces animal production and limits utilization of infested arable land for crop and livestock production. The total loss due to T&T is difficult to measure but roughly estimated to be about 200 million USD per year, including the most visible direct losses (meat and milk) and the costs of drugs.

Ticks and tick-borne diseases are widely distributed worldwide, particularly in tropical and subtropical regions. It has been estimated that eighty percent of the world's cattle population is exposed to tick infestation. Chemical control, dipping or spraying infested cattle with acaricides is the primary method of dealing with the cattle tick problem. However, widespread exposure to acaricides, often at sub-effective concentrations, has resulted in selecting resistant tick populations.

In Zimbabwe, as in all of sub-Saharan Africa, tsetse-transmitted trypanosomosis poses a severe challenge to food security by limiting livestock production and mixed animal–crop agriculture. This transboundary animal disease is characterized by a slow deterioration of health leading to death; it also reduces quality and quantity of meat and milk production and induces abortions.

Tsetse-transmitted Trypanosomoses are a family of infectious diseases unique to Africa that are caused by various species of blood parasites. They affect both people (Human African Trypanosomosis – HAT, or sleeping sickness) and animals (African Animal Trypanosomosis – AAT, or nagana), and they occur in 37 sub-Saharan countries over an area of more than 10 million km² – which corresponds approximately to one-third of Africa’s total land area.

Tsetse-transmitted trypanosomosisis a parasitic disease affecting both animals and humans. Because of its severe impact on livestock, it also hinders crop-livestock mixed farming in vast areas of sub-Saharan Africa, and is a major constraint to food security.

Tsetse-transmitted trypanosomosis is a lethal parasitic disease of humans and livestock. The disease severely limits mixed livestock–crop agriculture in over 10 million km2 of highly productive land in sub-Saharan Africa. Direct and indirect losses due to trypanosomosis are estimated in billions of dollars every year.

EMPRES Bulletin publication provides information from different sources on the effective prevention and progressive control of key Transboundary Animal Diseases (TADs), analysing animal disease risks to countries and reporting on progress in the control of such diseases in affected countries.

In this chapter we introduce basic concepts of Global Position System (GPS) and Geographic Information Systems (GIS) as they relate to the theory and practice of human African trypanosomiasis (HAT) mapping. We then present the main features of the atlas of sleeping sickness, the first attempt ever to systematically geo-reference at the village level all HAT reported cases and active screening activities.
