Epidemiological characterization of Leptospirosis in a hospital in northwestern Colombia during 2013-2023.

Abstract: Background: In Colombia the epidemiology of Leptospirosis is variable, there are multiple epidemiological conditions by region, and however the characterization of Santander in recent years is scarce. Methods: We carried out a primary observational study where we described the epidemiology from 2013 to 2023 of the reported cases of leptospirosis in a hospital in the city of Bucaramanga, Colombia. Descriptive statistical methods were used. Results: A total of 50 patients were recruited, 70% being male and 30% female. The ages ranged from 16-77 years. 80% of the patients came from urban areas and only 20% from rural areas. The source of contamination corresponded to contact with rodents and no sources of infection were found in any pet or companion animal. The main consultation symptom was fever, the average duration of symptoms was 8 + 5 days. The average hospital stay was 8 days. Conclusions: The characteristics of the population presented here do not differ consistently with other regions of Latin America. The epidemiology and clinical features are heterogeneous, requiring strict epidemiological surveillance to reduce the incidence of this type of infection.
