Overview

Q fever is more prevalent in the elderly and in males. It has been a notifiable disease in the US since 1999. Q fever is underreported, thus scientists cannot reliably assess its incidence.[1]

Epidemiology and Demographics

Age

  • Q fever is slightly more prevalent in elderly people; however, it is often seen in various age groups.
  • Q fever is occasionally seen in children, especially those who live on a farm.
  • In infected children younger than 3 years old, Q fever usually presents as pneumonia.[2]

Gender

  • Due to differing employment rates in typical professions that predispose people to contracting Q fever, men are more often affected than women.[3]

Developed Countries

  • In 1999, Q fever became a notifiable disease in the United States but reporting is not required in many other countries.
  • In Europe, Q fever often presents as hepatitis rather than pneumonia as it does in the United States.[1]

Developing Countries

  • C. burnetii is found everywhere except in Antarctica and New Zealand.
  • Q fever infections are often subclinical.
