Identifying Measles through Key Symptoms
Measles is characterized by a distinctive set of symptoms, often referred to as the 'three Cs': cough, coryza, and conjunctivitis. A crucial feature for distinguishing measles from other viral rashes is the presence of Koplik spots, which are small white lesions found in the buccal mucosa. In addition to these, a high fever exceeding 103°F not only marks the onset of the illness but can also provide a significant clue to diagnosing measles before the rash appears. The rash itself typically begins at the hairline and spreads downward toward the trunk and extremities, further reinforcing the diagnosis of measles over other viral infections.
