Overview

The world wide incidence of acute interstitial pneumonitis is approximately 97 cases per 100,000 individuals.

The incidence/prevalence of [disease name] is approximately [number range] per 100,000 individuals worldwide.
In [year], the incidence/prevalence of [disease name] was estimated to be [number range] cases per 100,000 individuals worldwide.
The prevalence of [disease/malignancy] is estimated to be [number] cases annually.

The case-fatality rate/mortality rate of acute interstitial pneumonitis is approximately 12500 per 100000 among in-hospital patients.^[1]
The mean time from symptom onset to death was approximately 20 days - 6 months.

Acute interstitial pneumonitis occur typically previously healthy individuals in the age group of 50 to 55years.^[2]

There is insufficient evidence to support the regional distribution of acute interstitial pneumonitis.
