MCCQE I Practice Test 2026 – Comprehensive Exam Prep

Infections like measles are associated with low vitamin A stores, and vitamin A supplementation dramatically reduces complications and mortality in affected children. The combination of conjunctivitis, coryza, and a face-starting rash is classic for measles, so the priority is to treat with high-dose vitamin A. This helps support mucosal integrity, improves immune response, and lowers the risk of eye problems (like keratitis and blindness) and severe pneumonia or diarrhea that can occur with measles. Giving the vitamin A promptly—typically a high oral dose appropriate for the child’s age on day 1 and again on day 2, with a follow-up dose weeks later—is the standard management because it directly improves outcomes.

Antibiotics aren’t indicated for a viral illness unless there’s a definite bacterial infection; antivirals are not effective against measles in routine practice; corticosteroids are not routinely used for uncomplicated measles and are reserved only for specific complications.
