Question

A child presents with fever and a rash spreading from the face, behind cheeks, and buccal mucosa to other body parts. On examination, Koplik's spot is present. What is the likely diagnosis?

• A. Measles
• B. Rubella
• C. Varicella
• D. Mumps

Answer 1

The Correct Option is A

The clinical presentation described in the question indicates a typical case of measles. Here’s the reasoning:

• Fever and Rash: Measles often starts with fever and a characteristic rash that begins on the face and then spreads to other parts of the body, such as the trunk and extremities.
• Rash Progression: The rash, which is erythematous and maculopapular, typically spreads from the head to the lower parts of the body, aligning with the symptoms described.
• Koplik's Spots: The presence of Koplik's spots, which are small, white lesions with a red base seen on the buccal mucosa, is a classic sign of measles. These spots appear before the rash and are pathognomonic for measles.

Given these clinical clues, the likely diagnosis is:

Measles
