Introduction
In general, conjunctivitis may occur during the course of measles. Measles is an acute infectious disease caused by the measles virus, typically presenting with high fever, cough, flu-like symptoms, and rash. The measles virus is an RNA virus capable of invading host cells and replicating within them, including the conjunctival tissues of the eyes.

Measles is an acute infectious disease caused by the measles virus, typically presenting with high fever, cough, flu-like symptoms, and rash. The measles virus is an RNA virus capable of invading host cells and replicating within them, including the conjunctival tissues of the eyes.
During infection, the measles virus directly infects conjunctival cells, triggering an inflammatory response that leads to symptoms of conjunctivitis such as redness, pain, a burning sensation, tearing, and increased eye discharge.
Simultaneously, the immune system initiates a series of immune responses after infection, including inflammation. In attempting to combat viral invasion, the immune system produces various inflammatory cells and mediators, further amplifying the immune response and contributing to ocular inflammation, including conjunctivitis.
In addition, the measles virus can enter the eyes via respiratory droplets, especially when an infected person coughs or sneezes. When the virus comes into contact with the conjunctiva, it can trigger conjunctivitis. Conjunctivitis is often one of the early signs of measles, commonly appearing before the skin rash develops.
If measles is suspected or related symptoms appear, prompt medical evaluation for diagnosis and treatment is recommended.
