    (SOC CHILENA INFECTOLOGIA, 2012) Terrazas, Solana; Olea, Andrea; Riedemann, Stella; Torres, Marisa
    Prevalence of leptospirosis in adults in Chile, 2003 Background: Leptospirosis is a zoonosis endemic in some regions in Chile. Since its inclusion into the list of notifiable diseases, the Chilean Ministry of Health was able to maintain an adequate surveillance of leptospirosis. Nonetheless, some cases are not reported due to subclinical disease or nonspecific symptoms. Objectives: Determine the national prevalence of leptospirosis and assess the epidemiological characteristics of seropositive individuals. Methods: Secondary data analysis of the National Health Survey, 2003. Results: National prevalence was 0.4%. Low socioeconomical status and female gender were characteristics, which were more frequently found in seropositive cases. The most common serovars were icterohaemorrhagiae, bratislava and pomona. Conclusion: We present the first epidemiological analysis of leptospirosis on a national level in Chile. Thus, the study contributes to the knowledge the epidemiological situation of this disease in Chile.
