Which statement about Koplik spots and the measles rash progression is correct?

• A. Koplik Spots Occur After The Rash
• B. Koplik Spots Not Occur In Measles
• C. Koplik Spots Occur Simultaneously With Rash
• D. Koplik Spots Precede The Maculopapular Rash

Answer: (D)

Koplik spots are an early mucosal sign of measles. They appear on the inside of the cheek as tiny bluish-white spots with a red halo during the prodromal phase, typically a day or two before the skin rash develops. This makes them a useful early clue: they precede the maculopapular rash rather than appearing after it or at the same time. The measles rash itself usually starts on the face around the hairline and spreads downward to the rest of the body over a few days. So the correct statement is that Koplik spots precede the maculopapular rash. They do occur in measles, and they are not simultaneous with the rash or after it.
