Children aged 6-11 months appear particularly susceptible to AOM, with frequency declining around age 18-20 months. The incidence is slightly higher in boys than in girls. A small percentage of children develop this disease later in life, often in the fourth and early fifth year. After the eruption of permanent teeth, incidence drops dramatically, although some otitis-prone individuals continue to have acute episodes into adulthood. Occasionally, an adult with an acute viral URTI but no previous history of ear disease presents with AOM.
