BENITEZ, Jesica D et al. Epidemiology and risk factors for invasive pneumococcal disease in pediatrics: Descriptive, postvaccinal study. Rev. cienc. tecnol. [online]. 2017, n.27, pp.4-10. ISSN 1851-7587.

The 13-valent pneumococcal conjugate vaccine was added to the National Immunization Program in 2011, and effectively administered since 2012. The aim of this study was to describe the post-vaccine epidemiology of pneumococcal invasive disease, in the pediatric population who come for consultation at the "Dr. F. Barreyro" and "SAMIC-Oberá" Hospitals, between May-2013 and April-2014. Clinical and epidemiological data were obtained and the suspected cases were confirmed by polymerase chain reaction. Twenty three cases were diagnosed, a seasonal pattern was observed with peaks in winter and spring. Patients older than 2 years old (82%), the masculine gender (65%), and who were diagnosed with pneumonia(69,6%) prevailed. Penicillin-sensitive pneumococci predominated throughout the study. Two serotypes (1 and 12F) were mainly distinguished. We did not observe any prevalence in the factors considered.It is necessary to continue active surveillance.
