Overview

The prevalence of adenoiditis is not completely known. In 2015, the prevalence and incidence of adenoiditis was estimated to be 12000 cases per 100,000 individuals worldwide.^[1] The prevalence of adenoiditis decreases with age. Adenoid tissue go through atrophy process after 10 years of age so adeoiditis is rarely seen after 15 .^[2]

Epidemiology and Demographics

Prevalence

The prevalence of adenoiditis is not completely known.

In 2015, the prevalence of adenoiditis was estimated to be 12000 cases per 100,000 individuals worldwide.^[1]

Incidence

The prevalence of adenoiditis is not completely known.

In 2015, the incidence of adenoiditis was estimated to be 12000 cases per 100,000 individuals worldwide.

Case Fatality Rate

The case fatality rate of tonsillitis is unknown.

Age

Adenoiditis commonly affects children.
The prevalence of adenoiditis decreases with age.
Adenoid tissue undergo atrophy after 10 years of age so adenoiditis is rarely seen after 15.
Adenoiditis can be seen in adults too, although it is rare in this patient population. However due to improved diagnostic modalities, adenoiditis is usually treated or removed during childhood.

Gender

Adenoiditis does not show predilection for any gender.

Race

Adenoiditis does not show predilection for any race.

Developed and Developing Countries

There is no geographic predisposition to tonsillitis.
