Which condition is characterized by high fever, cough, coryza, conjunctivitis, and a specific rash pattern that lasts around 7 days?

The condition characterized by high fever, cough, coryza (runny nose), conjunctivitis, and a specific rash pattern lasting around 7 days is measles. Measles is a viral infection caused by the measles virus, and it is known for its distinctive clinical presentation.

The illness typically begins with a prodrome phase where the individual experiences respiratory symptoms such as cough, alongside fever and conjunctivitis. The characteristic rash of measles follows the prodromal phase, often starting on the face and then spreading down the body. The rash is typically described as maculopapular and lasts about 4 to 7 days.

The early symptoms of fever, cough, coryza, and conjunctivitis combined with the timing and nature of the rash are classic indicators of measles, distinguishing it from other viral infections. Other conditions such as herpangina, rubella, and mumps have overlapping symptoms but do not present with the same symptom pattern and timing as measles.
