Comportamiento epidemiológico de la enfermedad de Hansen en Costa Rica, periodo 2018 a 2022 / Epidemiological Behavior of Hansen's Disease in Costa Rica, 2018-2022

Resumen Objetivos: Describir el comportamiento epidemiológico de la enfermedad de Hansen en Costa Rica durante el periodo 2018-2022 para la identificación y análisis de las tendencias de la patología con miras al desarrollo de estrategias más efectivas para su erradicación. Métodos: Estudio descriptivo observacional retrospectivo de casos con enfermedad de Hansen entre 2018 y 2022, realizado mediante el registro de la boleta de notificación individual y clasificados según la Clasificación Internacional de Enfermedades 10ma Revisión. Para determinar el número de casos nuevos del periodo de estudio, se solicitó la información anonimizada a la Unidad de Epidemiología de la Caja Costarricense de Seguro Social y a la Unidad de Epidemiología de la Dirección de Vigilancia de la Salud del Ministerio de Salud. Resultados: En Costa Rica, entre 2018-2022, se registraron 50 casos de enfermedad de Hansen (promedio anual de 10). El promedio de edad al momento del diagnóstico fue de 48,46 ± 17,88 años para el grupo en general, con un rango de edad de 15-78 años. La razón por sexos (hombre/ mujer) fue 2,33 (15/35). La provincia de Puntarenas registró 26 casos (52%). El cantón de Garabito se observó una tasa de prevalencia a nivel subnacional superior a 1 por cada 10000 habitantes. No se reportaron casos en menores de 15 años. La tasa media global de detección de enfermedad de Hansen durante el período de estudio fue de 0,2 (50/ 25 549 059) por 100000 habitantes. La tasa de detección de lepra disminuyó de 0,26 (13/ 5 003 402) a 0,249 (8 / 5213374) por 100000 habitantes entre 2018 y 2022. La proporción de casos clasificados como lepra multibacilar aumentó a 100% a partir del año 2019. La proporción de casos de lepra en mujeres disminuyó de 38,46 a 12,5%. Conclusión: A nivel nacional, la prevalencia de la enfermedad mantuvo los niveles de eliminación. No obstante, a nivel sub- nacional aún persisten cantones con niveles superiores a 1 por 10000 habitantes.

Abstract Objective: To describe the epidemiological characteristics of leprosy in Costa Rica from 2018-2022. Methods: Retrospective observational descriptive study from 2018 to 2022 of Hansen's Disease cases using individual notification records under the International Classification of Diseases 10th Revision. To determine the number of new cases, anonymized information was requested from the Epidemiology Unit of the Costa Rican Social Security Fund and the Epidemiology Unit of the Health Surveillance Directorate of the Ministry of Health. Results: In Costa Rica, between 2018-2022, 50 cases of Hansen's disease were registered (annual average of 10). The mean age at diagnosis was 48.46 ± 17.88 years for the group in general, with an age range between 15 -78 years. The sex ratio (male/ female) was 2.33 (15/35). The province of Puntarenas recorded 26 cases (52%). The canton of Garabito registered a prevalence rate at the subnational level of more than 1 per ten thousand inhabitants. No cases in children under 15 years of age were reported. The overall mean leprosy detection rate during the study period was 0.2 (50/25 549 059) per 100000 population. The leprosy detection rate decreased from 0.26 (13/5,003,402) to 0.249 (8/5213374) per 100000 population between 2018 and 2022. The proportion of cases classified as multibacillary leprosy increased by 100% in 2019. The proportion of leprosy in women decreased from 38.46% to 12.5%. Conclusion: Nationwide, the disease prevalence is maintained at elimination levels. However, at the subnational level, districts with rates higher than 1 per 10000 inhabitants still exist.

Long term effect of infection control practices and associated factors during a major Clostridium difficile outbreak in Costa Rica.

INTRODUCTION: The C. difficile BI/NAP 1 hyper virulent strain has been responsible for the nosocomial outbreaks in several countries. The present study describes the infection control strategies utilized to achieve outbreak control as well as the factors associated with a C. difficile BI/NAP 1 hyper virulent strain outbreak in Costa Rica. METHODOLOGY: A descriptive analysis of the C. difficile outbreak was completed for the period of January 2007 to December 2010 in one affected hospital. An unmatched case-control study was subsequently performed to evaluate the association of exposure factors with C. difficile infection. RESULTS: The pattern of the outbreak was characterized by a sharp increase in the incidence rate during the initial weeks of the outbreak, which was followed by a reduction in the incidence curve as several infection control measures were implemented. The C. difficile BI/NAP1 infection was associated with the prescription of antibiotics, in particular levofloxacin (OR: 9.3; 95%CI: 2.1-40.2), meropenem (OR: 4.9, 95%CI: 1.0-22.9), cefotaxime (OR: 4.3, 95%CI: 2.4-7.7), as well as a medical history of diabetes mellitus (OR: 2.9, 95%CI: 1.5-5.8). CONCLUSIONS: The infection control strategies implemented proved to be effective in achieving outbreak control and in maintaining the baseline C. difficile incidence rate following it. The reported C. difficile outbreak was associated with the prescription of broad-spectrum antibiotics and a medical history of diabetes.
