Análisis de la mortalidad a partir de certificados de defunción entre 2010 y 2015. Cálculo de tasas de mortalidad departamentales y municipales ajustadas por sexo y edad.Resultados El 56,8% de las defunciones ocurrieron en mujeres y 28,7% en personas de 50 a 59 años. En 2010 la tasa de mortalidad nacional fue de 0,28 por cada 100 000 personas, y Casanare registró la más alta (0,59 por cada 100 000 personas). En 2011, la tasa fue de 0,24, y Buenaventura registró la más alta (0,51). En 2012, la tasa fue de 0,27, y Guajira registró la más alta (0,34). En 2013, la tasa fue de 0,27, y la más alta se presentó en Arauca (0,83). En 2014, la tasa fue de 0,32, y la más alta ocurrió en Putumayo (1,14). En 2015 la tasa fue de 0,23 y Santa Marta registró la más alta (0,58). Por municipios, Sativanorte, Arcabuco (Boyacá), San Miguel, la Paz (Santande...

Typhi) is the causative agent of typhoid fever; a systemic disease affecting~20 million people per year globally. There are little data regarding the contemporary epidemiology of typhoid in Latin America. Consequently, we aimed to describe some recent epidemiological aspects of typhoid in Colombia using cases reported to the National Public Health Surveillance System (Sivigila) between 2012 and 2015. Over the four-year reporting period there were 836 culture confirmed cases of typhoid in Colombia, with the majority (676/836; 80.1%) of reported cases originated from only seven departments. We further characterized 402 S. Typhi isolates with available corresponding data recovered from various departments of Colombia through antimicrobial susceptibility testing and molecular subtyping. The majority (235/402; 58.5%) of these typhoid cases occurred in males and were most commonly reported in those aged between 10 and 29 years (218/402; 54.2%); there were three (0.74%) reported fatalities. The overwhelming preponderance (339/402; 84.3%) of S. Typhi were susceptible to all tested antimicrobials. The most common antimicrobial to which the organisms exhibited non-susceptibility was ampicillin (30/ 402;7.5%), followed by nalidixic acid (23/402, 5.7%). Molecular subtyping identified substantial genetic diversity, which was well distributed across the country. Despite the diffuse pattern of S. Typhi genotypes, we identified various geographical hotspots of disease associated with local dominant genotypes. Notably, we found limited overlap of Colombian genotypes with organisms reported in other Latin American countries. Our work highlights a substantial burden of typhoid in Colombia, characterized by sustained transmission in some regions and limited epidemics in other departments. The disease is widely distributed across the country and associated with multiple antimicrobial susceptible genotypes that appear to be restricted to Colombia. This study provides a current perspective for typhoid in Latin
