What is a common cause of viral conjunctivitis?

Viral conjunctivitis is most commonly caused by the adenovirus, which is a leading pathogen responsible for this eye condition. The adenovirus can easily spread and often causes outbreaks, particularly in crowded settings such as schools or daycare centers. Symptoms typically include redness, tearing, and a gritty sensation in the eye, along with potential associated symptoms like a cold or respiratory infection since adenoviruses can also cause upper respiratory ailments.

While other viruses, such as the influenza virus, can contribute to conjunctival irritation, they are not the primary cause of viral conjunctivitis itself. Bacterial infections caused by organisms like Streptococcus bacteria or Staphylococcus aureus are associated with bacterial conjunctivitis rather than viral. This distinction is essential in clinical practice to ensure appropriate treatment and management.
