TAMAYO REUS, Caridad María et al. Pneumoccocal disease in a patient under 5 years. MEDISAN [online]. 2018, vol.22, n.8, pp.695-706. ISSN 1029-3019.


Pneumococcal disease affects mainly people in the extreme ages of life. In this sense, "Dr. Antonio María Béguez Caesar" Southern Teaching Pediatric Hospital constitutes a place of centinel surveillance of the Pneumococcus National Project, which served as motivation to develop the present investigation on this disease.


To describe the epidemiological, clinical, microbiological and imaging characteristics in patients younger than 5 years admitted due to a pneumoccocical disease.


An observational, descriptive and prospective study of 170 patients younger than 5 years admitted to the above mentioned hospital in the period 2014-2016 was carried out, for presenting pneumoccocal disease.


The early suppression of the maternal feeding (52.3 %) and the presence of coexisting smokers (44.7 %) as main risk factors, besides fever (100.0 %), cough (96.0 %), chest indrawing (74.1 %) and polypnea (70.0 %) as the most frequent symptoms prevailed in the series; while the pneumonia was presented in 82.3 % and there was 10.0 % positiveness to pneumoccocus, by serotypes 19A, 19F, 14 and 6A, with 66.6 % colonization in infants. On the other hand, lethality and proportional mortality for pneumonia were of 2.85 and 8.0 %, respectively, without deaths due to pneumoccocus.


Pneumoccocus isolation was low, with prevalence in colonized infants and with mortality indicators due to non pneumoccocal pneumonia, which suggests that the short age is a death risk due to this cause.
