Overview

The incidence of chicken pox varies among various age groups. Varicella commonly affects children less than 10 years of age with the highest incidence among children 1-4 years of age. The incidence of chickenpox for children between 0 to 4 years of age is 5234 per 100,000 individuals. Between the years 1990-1994, the case fatality rate of chickenpox in the US/UK is 2-3 per 100,000 individuals. In the developed countries chickenpox causes around 3 deaths per 100,000 individuals.

Epidemiology

Incidence

The incidence of chicken pox varies among various 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 individuals
  • For age groups 5 to 9 years 4132 per 100,000 individuals
  • For age groups 10 to 14 years 1404 per 100,000 individuals
  • For age groups 15 to 19 years 610 per 100,000 individuals
  • For age groups >20 years 175 per 100,000 individuals

The rates of incidence of chickenpox continues 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 generally does not vary by gender.
  • However, chickenpox is more prevalent in females between the ages of 15 - 24 as 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
    • 1500 – 1600 per 100,000 persons per year
  • Deaths
    • 3 deaths per 100,000 individuals
