What is the likely diagnosis for an adolescent female presenting with low-grade fever, maculopapular rash, and posterior auricular lymphadenopathy?

• A. Rubeola
• B. Varicella
• C. Rubella
• D. Coxsackie virus infection

Answer: (C)

In this scenario, the adolescent female's presentation of low-grade fever, maculopapular rash, and posterior auricular lymphadenopathy is highly indicative of rubella, also known as German measles. Rubella is characterized by the gradual onset of a mild fever, followed by a distinctive rash that typically starts on the face and then spreads downward. A notable clinical feature of rubella is posterior auricular lymphadenopathy, which is prominent and often helps differentiate it from other viral infections. The combination of these symptoms suggests a viral cause, and rubella is known for these specific clinical signs. The low-grade fever, along with the rash, usually occurs within 1 to 5 days after exposure, which is a common timeline for rubella infection. While rubeola (measles) can present with a rash and fever, it usually has a higher fever and tends to involve conjunctivitis and Koplik spots in the mouth, which are not mentioned here. Varicella (chickenpox) typically presents with a vesicular rash rather than a maculopapular one, along with pruritus. Coxsackie virus infections can present with a variety of symptoms, but they typically do not present with
