Background: The Coquimbo Region in Chile has the highest incidence of hydatidosis in central and northern Chile. Aim: To analyze the incidence of human cystic echinococcosis (CE) in the Coquimbo Region between 2008 and 2012. Material and Methods: Official records of reported cases were analyzed. The association location, age and sex with the presence/absence of CE was analyzed by means of logistic regressions. The incidence was reported as cases per 100,000 inhabitants. Results: The mean annual incidence was 2.6 cases per 100,000 inhabitants, which ranged from 3.1 (2010) to 1.9 (2012) cases. The districts with higher incidence were Punitaqui (21.2 cases), Paihuano (9 cases), Rio Hurtado (8. cases), Canela (8.1 cases), Monte Patria (7.9 cases), Vicuña (6.9 cases) and Combarbalá (6.9 cases). The incidence in these locations was significantly higher than elsewhere in the region. Males had a significantly higher incidence than females (3.3 and 1.8 respectively). Incidence increased significantly with age, notably increasing after 45 years old. Conclusions: Rural locations had the highest incidences of CE in the Coquimbo Region. The disease was reported more commonly in adults and mainly in men.
