ABSTRACT
Background Bartonella bacilliformis, the etiological agent of Carrion's disease and presumed to be transmitted by phlebotomine sandflies, is endemic to the high-altitude valleys of the South American Andes, including Colombia. Methods This observational, retrospective study in which the incidence of bartonelloses (International Classification of Diseases, 10th revision (ICD-10) codes A44.0-A44.9) in Colombia, from 2009-2013, was estimated based on data extracted from the personal health records system (Registro Individual Prestación Servicios, RIPS). Using the official population estimates of the National Statistics Department (Departamento Administrativo Nacional de Estadísticas, DANE), crude and adjusted incidence rates were estimated (cases/100,000 population). Results A total of 1,389 cases were reported (median 289/year), for a cumulative national rate of 3.02 cases/100,000 population; 91.2% were female; 66.8% were <40-year-old (3.8% <9.9-year-old). The cases were 2.9% Oroya fever (A44.0), 13.1% verruga peruana (A44.1), and the rest (85.3%) were other forms of bartonelloses (A44.8-A44.9). The highest rates of Oroya fever were reported in Bolivar (2.5 cases/1,000,000 population). For verruga peruana highest number of cases were reported in Antioquia (32; 17.8%; 5.21 cases/1,000,000 population) and the highest rate at Magdalena (11.54 cases/1,000,000 population) (Risaralda, 6.45; Caldas, 5.1). For other forms of bartonelloses, the highest rates were reported at Magdalena (48.65 cases/1,000,000 population), followed by Huila (32.8) and La Guajira (18.9). At Nariño, Putumayo, Amazonas, Cauca, and Valle del Cauca, 11.7% of the cases of the country were reported. Conclusions Lutzomyia columbiana, the potential vector of Bartonella bacilliformis in Colombia, is distributed not only in Nariño, Cauca, and Valle del Cauca but also in the Antioquia, Caldas, Huila, La Guajira, Risaralda, Cordoba, and Caribbean areas. Given this distribution, the transmission would be occurring, as seen in reported cases, in more areas than previously described by classic reports of these diseases in the country.
ABSTRACT
Infection due to Legionella pneumophila has been not studied in Colombia, although it is present. The observational, retrospective study in which the incidence of legionellosis in Colombia, 2009-2013, was estimated based on data extracted from the personal health records system (Registro Individual de Prestación de Servicios, RIPS) using the ICD-10 codes A48.1 (Legionnaires' disease) and A48.2 (Pontiac Fever). Using official population estimates of the National Administrative Department of Statistics (DANE), crude and adjusted incidence rates were estimated (cases / 100,000 pop). During the period, 206 cases were reported (mean of 41.2 per year) for the cumulated national rate of 0.45 cases / 100,000 pop. The clinical form of legionellosis with the highest incidence rates was the non-pneumonic Legionnaires' disease (0.39 cases / 100,000 pop) with women being the main affected (0.42 cases / 100,000 pop). The territory with the highest incidence rate was Bolivar department (1.94 cases / 100,000 pop), followed by La Guajira (1.7 cases / 100,000 pop). Finally, age groups with the highest morbidity were 0-9.999 years old (1.16 cases / 100,000 pop) and system of identification for social subsidies beneficiaries (SISBEN) category with the highest number of total cases was level one (88 cases). According to these results, we can show that legionellosis in Colombia is more common than it could be thought. Nevertheless, cross-sectional and prospective studies should be conducted in our country in order to improve the knowledge of incidence, prevalence, and burden of disease.
ABSTRACT
Yellow fever (YF) is a haemorrhagic viral disease with a high case fatality rate. It is considered a reemerging infectious disease of remarkable importance. During the last outbreaks in Angola (2015-2016) and Brazil (2016-2017), many cases of YF emerged despite high YF vaccination coverage, increasing the risk of major epidemics in the Americas. Several factors, including the vast border and migratory status of Brazil, the widespread distribution of Aedes mosquitoes and the lack of efficient health policies and surveillance systems, favour this complex epidemiological scenario of reemergence. Therefore, mass vaccination of the population at risk, public health awareness and preparedness are urgently needed in this region. This article describes the current global epidemiological situation of YF, focusing especially on the Americas, as well the risk and vulnerabilities in the region that would be of concern for major expansion to other countries apart from Brazil.
