What are Koplik spots indicative of?

Koplik spots are a clinical hallmark of measles, also known as rubeola. These spots are small, bluish-white lesions that appear on the buccal mucosa, typically opposite the lower molars, and they are usually seen around the time other measles symptoms begin, such as fever and a characteristic rash.

The presence of Koplik spots is considered a key diagnostic feature of measles due to their specificity. While other viral infections may cause rashes or similar symptoms, Koplik spots are unique to measles and can help differentiate it from other conditions. They usually appear 1-2 days before the measles rash and resolve as the rash develops, which further links their appearance with measles infection progression.

Understanding the significance of Koplik spots is critical for prompt identification and management of measles, especially in pediatric patients. Recognizing these spots can aid healthcare providers in implementing appropriate public health measures to control outbreaks, as measles is highly contagious.
