[Characterization of infectious conjunctivitis in a fourth-level care center, Bogota, Colombia].

Objective: The purpose of this study is to describe the characteristics of the populations that consulted to the emergency service due to conjunctivitis from March 1 of 2019 to March 1 of 2021 and evaluate the frequency of presentation of contagious ocular pathologies like is the case of bacterial conjunctivitis. Methods: A descriptive cross-sectional study was conducted in a historical cohort in the Department of Surgery, Ophthalmology Unit of the Hospital Universitario San Ignacio, Bogotá D.C. from March 2019 to March 1, 2021. The study included patients with a diagnosis of bacterial conjunctivitis and patients with a diagnosis of superinfected viral conjunctivitis, and excluded all patients with a positive result for COVID-19 and patients with symptoms suggestive of SARS-infectionCoV-2. Of the patients, 629 met the selection criteria.

The majority of the patients presented with viral conjunctivitis, followed by superinfected viral conjunctivitis, and bacterial conjunctivitis.
