The dengue surveillance system in Panama during the 1994 and 1995 epidemics shows the following results: In 1994 we registered 793 dengue cases and a year after 3,083 dengue cases, with three dengue haemorrhagic cases (one death). To estimate the accumulated incidence rates in 1994-1995 period, we consolidated the cases. The highest risk of dengue and the highest dengue haemorrhagic propension were observed in: West Panama (709.49 per 100,000 persons), Los Santos (405.74 per 100,000 persons), Herrera (337.62 per 100,000), Metropolitana (126.98 per 100,000) and San Miguelito (125.10 per 100,000 persons).
