Diagnosis was done by blood smear, culture and serology. CDC light traps and Shan­non trap in intra y peridomiciliary ambient were used for phlebotominae sandflies capture. RESULTS: At 21 places the disease affected 140 people, 25 between 1 and 4 year-old, 81 women and 59 men; 121 presented the acute phase of the disease, 16 the intercalar phase and 3 the eruptive phase. The area population cutivates coca, coffee and cacao.
