ABSTRACT

In the region of la Araucania, locate in the south of Chile (37º24ï-39º34ï South lat.), the economy is based in cattle raising and agriculture. The case of human hydatidosis, mortality and notification registered in la Araucania 1991-1998 are reviewed. The rate for hydatid disease is 38.5 per 100,000 population. Liver (47.1 percent) and lung (40.7 percent) were the most affected viscera. Days in hospital, 11-20 the 56.1 percent. Disease in female is 51.1 percent. The mortality rate is 0.8 per 100,000, the most frecuently affected county is Imperial. The age 15-44 years is the most affected. The notification rate is 8.74 per 100,000 population. The rate for hydatid disease is higher than the rate of notification, then necessarily there exist a subnotification. We think that it is necessary to investigate the serological prevalence of hydatidosis in the population of the IX Región Araucania
