Overview
Epidemiology
Incidence
The incidence of chicken pox varies among age groups. The incidence rates per 100,000 persons in each age group were as follow:
- For age groups 0 to 4 years 5234 per 100,000 person
- For age groups 5 to 9 years 4132 per 100,000 person
- For age groups 10 to 14 years 1404 per 100,000 person
- For age groups 15 to 19 years 610 per 100,000 person
- For age groups >20 years 175 per 100,000 person
These rates continued to decline for older age groups [1]
Case Fatality Rate
Between the years 1990-1994, case fatality rate in the US/UK is 2-3 per 100,000.
- The case fatality rate among children was 1 per 100,000.
- In 2008 the case fatality rate in Brazil estimated case fatality rate is 4 per 100,000. [2]
- In 2000 the case fatality rate in Guinea Bissau was approximately 129 per 100,000 case, 50 times higher than US/UK.
- In 1970, the case fatality rate in India among adults was 52 per 100,000 cases, 20 times higher than US/UK.
- Worldwide, the case fatality rate among adults was 20-25 per 100,000. [2]
Demographics
Age
- The prevalence of chicken pox decreases with age.
- Varicella commonly affects children less than 10 years of age with the highest incidence among children 1-4 years of age.
Gender
- The prevalence and incidence of chickenpox does not vary by gender.
- Chickenpox is more prevalent in females between the ages of 15 - 24 when compared to males.[3]
Race
- There is no racial predilection for chickenpox.
Developed Countries
The epidemiology and demographics of chickenpox in the developed countries are as follows:[2]
- Incidence
- 15.0 – 16.0/1,000 persons per year
- Deaths
- 3 deaths per 100,000 cases
