A serologic study for prevalence of Chagas infection was performed in Salamanca, Northern Chile. Indirect immunofluorescence and indirect hemagglutination reactions were used in samples from 1529 females and 698 males representing 10% of the population. A total of 499 positive results were obtained. The incidence of infection increases at a mean rate of 1% per year up to age 30, declining slowly in older groups to reach a maximum of 39.7% for the population. These data will be used to implement appropriate serologic surveillance programs and sanitary control measures in this and other populations.
在智利北部的萨拉曼卡进行了一项关于恰加斯病感染患病率的血清学研究。对1529名女性和698名男性的样本采用间接免疫荧光和间接血凝反应，这些样本占总人口的10%。共获得499个阳性结果。感染发病率在30岁之前平均每年以1%的速度上升，在老年组中缓慢下降，总体最高达到39.7%。这些数据将用于在该人群及其他人群中实施适当的血清学监测计划和卫生控制措施。
