Overview
Epidemiology and Demographics
Incidence
- The worldwide incidence of acute otitis media is estimated to be 10,000/100,000 individuals.[1]
- 51% of the incidence is in children under five years old.
- Incidences range from 3,640/100,000 in Central Europe up to 43,337/100,000 in Sub-Saharan West Africa.
- The worldwide incidence of chronic suppurative otitis media is 476/100,000 individuals worldwide.[1]
- 22.6% of the incidence is in children under five years old.
- Incidences range from 170/100,000 in Andean Latin America to Oceania with 937/100,000 individuals.
Case Fatality Rate
- The case fatality rate for otitis media is approximately .003%.[2]
Age
- The majority of otitis media patients are children under 5 years old.[1]
- Between 50 and 85% of children under 3 years old have experienced cases of otitis media.[2]
- This is due to smaller, less developed eustachian tubes making fluid buildup more likely, as well as weaker immune systems.[3]
- Chronic suppurative otitis media can persist into adulthood if not successfully treated.[4]
Developing Countries
- Otitis media is most prevalent in developing countries, specifically Sub-Saharan West Africa and Southeast Asia and Oceania.[2]
- The incidence of otitis media in the above countries is between two and eight times higher than the rest of the world.
- The following risk factors are more prevalent in developing countries, correlated to the increase in otitis media incidence:
- Exposure to HIV
- Malnutrition
