Seasonal respiratory syncytial virus, human metapneumovirus and influenza activity were temporally associated with increased diagnoses of acute otitis media in children, according to the results of a study published online recently.
Therefore, these findings support the role of individual respiratory viruses in the development of AOM and also underscore the potential for respiratory viral vaccines to reduce the burden of AOM, the study researchers wrote in their findings published in the Pediatric Infectious Disease Journal.
Chris Stockmann, MSc, division of pediatric infectious diseases, department of pediatrics, University of Utah Health Sciences Center, Salt Lake City, used electronic medical records to analyze nine seasons of respiratory viral activity (2002-2010) among children in Utah aged younger than 18 years with outpatient visits and ICD-9 codes for AOM.
During the study period, 46,460 (48%) of 96,418 respiratory viral tests were positive. The most commonly identified viruses included respiratory syncytial virus (RSV; 22%); rhinovirus (8%); influenza (8%); parainfluenza (4%); human metapneumovirus (3%); and adenovirus (3%).
A diagnosis of AOM was coded during 271,268 ambulatory visits, and there were significant associations between peak activity of RSV, human metapneumovirus and influenza A with office visits for AOM.
Adenovirus, parainfluenza and rhinovirus were not associated with visits for AOM.
