Overview
With a rapid ascension to high altitudes in 1 to 3 days, more than 50% of people develop altitude sickness. The incidence of clinical HAPE in unacclimatized travelers exposed to high altitude (~ 4,000 m) appears to be less than 1%. In over 30 years of research experience, the U.S. Army Pike's Peak Research Laboratory, utilizing about 300 sea-level resident volunteers (and more than 100 staff members) rapidly and directly exposed to high altitude, only 3 were evacuated with suspected HAPE.
Epidemiology and Demographics
Incidence
Prevalence
- The prevalence of altitude sickness is approximately as following:[2]
- 9000 per 100,000 individuals of people at 2850 m
- 13000 per 100,000 individuals of people at 3050 m
- 34000 per individuals of people at 3650 m
- 53,000 per 100,000 individuals of people at 4559 m
Case-fatality rate/Mortality rate
- In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
- The case-fatality rate/mortality rate of [disease name] is approximately [number range].
Age
- Patients of all age groups may develop [disease name].
- The incidence of [disease name] increases with age; the median age at diagnosis is [#] years.
- [Disease name] commonly affects individuals younger than/older than [number of years] years of age.
- [Chronic disease name] is usually first diagnosed among [age group].
- [Acute disease name] commonly affects [age group].
Race
- There is no racial predilection to [disease name].
