Considering that there was not any regional survey in Isfahan, Iran regarding the epidemiology of acute respiratory tract infections (ARTI) in different age groups of general population, the aim of this study was to determine the epidemiologic feature of ARTIs in Isfahan using multiplex polymerase chain reaction (PCR) method.
METHODS
In this cross-sectional study, patients aged <80 years with symptoms of ARTI were studied, during 2009-2010 Nasopharyngeal and dry throat swab specimens were collected and pathogens of ARTI was determined using multiplex real-time PCR.

Symptoms such as sore throat (86.3%), coryza (68.0%) and dry cough (54.3%) were the most common symptoms in all studied groups, whereas fever was the most clinical presentation of younger patients (<15 years old) and headache and skeletal pain were the most common symptoms of older patients (>15 years old). Rhinovirus was the most common cause of ARTI in patients aged <5 years and those aged >50 years. Influenza virus B was the most common cause of ARTI in patients aged 5-50 years.
