The most common pathogen isolated was Adenovirus (49%), followed by <i>Bordetella pertussis</i> (41%) from our previous investigation, the most prevelant microorganisms were <i>Mycoplasma pneumonia</i> (26%) and Influenza-B (19.8%). Coinfections were reported in 53.5% of samples and the most common association was found between <i>M. pneumoniae</i> and Adenovirus (9%). <b>Conclusions:</b> There was a high prevalence of Adenovirus, <i>Mycoplasma pneumoniae</i> and other etiologies in patients with a probable diagnosis of pertussis. Despite the presence of persistent cough lasting at least two weeks and other clinical characteristics highly suspicious of pertussis, secondary etiologies should be considered in children under 5 years-old in order to give a proper treatment.</p><sup><b></b></sup><p></p
