[Epidemiology of Human Trypanosomiasis in the Luba Focus, in Equatorial Guinea]

In Equatorial Guinea, the human trypanosomiasis, after an intensive surveillance beginning in the 30's, seemed to be controlled by the end of the 60's. A lack of surveillance provoked a surge of different foci, confirmed in 1982 by the spontaneous presentations of sick in the hospitals of the old foci. These processes have been observed in the Luba focus (ex San Carlos) on the island of Bioko (ex Fernando Poo). The situation was grave in 1985 and a survey was organized by the "Centro de Control de la Tripanosomiasis" (Ministerio de Sanidad de Guinea Ecuatorial--Agencia Española de Cooperación Internacional) to delimit the focus, to evaluate the presence of the disease in the different villages, to know the characteristics and the distribution of the vector, and evaluate the impact of the mono-pyramidal trap as the method of anti-vectorial control. The results have been obtained and presented in the conclusion.
