C. Otitis media.
The disorder shown in the picture above represents measels.
Measles is a highly communicable acute disease. It is also known as rubeola and is marked by prodromal fever, cough, coryza, conjunctivitis, and pathognomonic enanthem (i.e., Koplik spots), followed by an erythematous maculopapular rash on the third to seventh day.
Infection confers life-long immunity.
A generalized immunosuppression that follows acute measles frequently predisposes patients to bacterial otitis media and bronchopneumonia.
In approximately 0.1% of cases, measles causes acute meningo-encephalitis,which is the most serious complication. Subacute sclerosing panencephalitis (SSPE) is a rare chronic degenerative disease that occurs several years after measles infection.
