[Where is the focus of human trypanosomiasis in Mossaka (Congo)]. / Où en est le foyer de trypanosomiase humaine de Mossaka (Congo)?

ABSTRACT

The Mossaka focus of sleeping sickness (on the Sangha, Cuvette area, in Congo) has been progressing dramatically for last years. In 1989, after a prospection we had accomplished in the focus, we had insisted on the priority to limit an extension of the disease. Since then the situation get worse, regarding to the number of patients detected (74 in 1987, 171 in 1989, 200 in 1991) and the concerned population. The number of villages where we detected patients is raised from 3 in 1987 to 12 in 1989 and 17 in 1991. If measures are not taken quickly, we can await a dramatic extension of lower Sangha focus.
