Koplik's spots are associated with which disease?

Koplik's spots are a specific clinical manifestation associated with measles, which is a highly contagious viral infection. These spots appear as small, white lesions with a red halo found inside the cheeks, typically near the molars, and usually occur 1 to 2 days before the onset of the measles rash. They are considered a classic indicator of measles and are often used by healthcare providers to help in diagnosing the disease.

Understanding the significance of Koplik's spots emphasizes the importance of early identification and prevention strategies for measles, as it is necessary for managing outbreaks and protecting public health. In contrast, the other diseases listed do not involve Koplik's spots as part of their clinical features, which helps differentiate measles from these other conditions.
