ORTIZ R, Celely et al. Spatial distribution and incidence of dengue cases: analyses of Medellín - Colombia situatio. Rev. Fac. Nac. Salud Pública [online]. 2013, vol.31, n.3, pp.329-337. ISSN 0120-386X.

OBJECTIVE:To analyze the spatial distribution of incidence and dengue cases. METHODOLOGY 17.400 dengue cases were spatially located by means of the addresses of patients which were reported by Data Generating Primary Units to Health Secretary of Medellin during 2007 to 2011. Dengue incidences were calculated and geospatially ranked with ArcGIS 9.3 software, and they were categorized by risk level according to Pan American Health Organization. RESULTS AND DISCUSSION:the disease was distributed heterogeneously in different neighborhoods of the city. The years 2007 and 2010 had the highest number of cases, corresponding to epidemic years, while other years showed an endemic behavior. In 2007 noneof the neighborhoods was at very high risk category, but at the year 2010, 49 neighborhoods were ubicated inside this category. For endemic years, according to dengue incidence, of in 249 neighborhoods of the city, for the years 2008 and 2009 just two of them were found in high risk and none one for the 2011 year, and a largely average of the neighborhoods in these years were located in low risk.
