Background: Viruses are considered the most common cause of infectious conjunctivitis. PCR has been approved as the best standard method to diagnose viral conjunctivitis. This study was conducted to investigate epidemiological patterns of conjunctivitis in Hamadan, west Iran. In addition, the frequency of the most important cause of infectious conjunctivitis diagnosed by PCR and its seasonal variations and association with certain socioeconomic and health factors were studied.
Methods: In this cross-sectional study, 125 patients with suspected viral conjunctivitis or keratoconjunctivitis in Hamadan, west Iran from July 2016 to June 2017 were examined for the presence of herpes simplex virus 1 (HSV1), HSV2, varicella-zoster virus (VZV), adenovirus. and Chlamydia trachomatis using multiplex real-time PCR.
Results: Adenoviruses were the most prevalent pathogens (94.4%). HSV1 was found in two (1.6%) patients. HSV2, VZV, and C. trachomatis were not seen in any patients. There was no difference in acquisition of conjunctivitis between men and women. A total of 55 (44%) patients attended the clinics in summer.
Conclusion: This study demonstrated that adenoviruses were a much more common viral cause of conjunctivitis in the studied region compared to findings in other regions. In addition, the acquisition rate of eye infection is expected to decrease dramatically in this region through control of adenoviruses. Demographic variables ie, age, sex, and income level, were not significantly associated with acquisition of viral infection.
