commonly known as "pink eye," is an inflammation of the conjunctiva caused by a viral infection. It is highly contagious and often occurs in outbreaks, especially in schools or crowded environments.

- Other viruses include herpes simplex virus (HSV), varicella-zoster virus (VZV), and enteroviruses.

- Direct contact with infected eye secretions or contaminated objects (e.g., towels, makeup).
- Respiratory droplets or hand-to-eye contact.
- Based on clinical examination and patient history.
- Lab tests (e.g., viral cultures or PCR) are rarely needed but may be used in severe cases.
- **Supportive care** is the mainstay as it is usually self-limiting (7–14 days).
- Artificial tears or lubricants to soothe irritation.
- Cold compresses for swelling and discomfort.
- Avoid wearing contact lenses until the infection resolves.
