Adenovirus in Pharyhgeal Discharge of children with 3 months to 15 years of age through rapid imunoflaoorscence

Respiratory tract infections causes 4.5 million children death in the world annually that occur mostly in developing countries like Iran. Bacterial and viral pathogens are responsible for this event and Adenovirus is one of the major responsible agents. According to multiple survey, incidence of viral pathogens in different world region is different so local survey is needed to describe regional incidence of different viral pathogens. Rapid test for detection of respiratory pathogens help us to select appropriate treatment and avoidence of antibiotic overusage. So abuse the aim of this study was to evaluate incidence and clinical presentation of Adenovirus infection in children in Tehran with rapid test. This study is a descriptive-cross sectional analysis. All 3 month to 15 year old children with upper respiratory tract infection that come to OPD of Rasol-e-Acram Hospital in one year(1385) are included.Direct smear of patient's throat was evaluated by rapid chromatography test for adenovirus infection.
