Examines trypanosomiasis in Kenya and how it is involved in the clash of interests over land betwen conservationists and cattle herders. Conservationists argue for the preservation of the tsetse fly which protects the country's diminishing forest areas by making them uninhabitable for men and cattle. However, herdsmen from the drought-ridden plains risk infection by clearing forest to plant forage crops. They fail to maintain fly traps provided by the British Overseas Development Agency, and encourage drug-resistant trypanosomiasis by treating their cattle with haphazard medication. The farming community around Lake Victoria suffers periodic invasions of tsetse flies carrying the trypanosome parasite that infects humans and here the choice is between inadequate treatment at a local clinic or traditional medicine.
