[Bocavirus in infants under 5 years with acute respiratory infection. Chaco Province, Argentina, 2014].
Acute respiratory infection (ARI) is the most frequent pathology along human life, being the most common cause of morbidity and mortality in children under 5 years. The aim of this study was to determine the frequency of bocavirus (BoV) in infants under 5 years with symptoms of ARI from north Argentina (Chaco province). The study was performed on nasopharyngeal aspirates from 488 patients, in the period of January-December 2014. The samples were tested by real time PCR and 36 positive BoV cases (7.4%) were detected. The period with the highest detection rate was June-September with 28 cases (77.8%), of which 26 (72.2%) were infants between 6-18 moths of life. In half of BoV positive cases this virus was detected as single infection of the upper respiratory tract, and in the remaining 50%, as concomitant infection with other microorganisms. To our knowledge, this would be the first study on molecular epidemiology of BoV in northern Argentina. We emphasize the importance of investigating these new viruses capable of generating acute respiratory disease and also to disseminate awareness on their circulation within the community.
