Overview

In the USA, the incidence of Mycoplasma pneumonia is approximately 600 per 100,000 individuals. Patients younger than 40 years of age (especially between 5 and 20 years of age) are more commonly affected with Mycoplasma pneumonia. There is no gender predilection to the development of Mycoplasma pneumonia, but men may experience a more severe disease compared with women. The incidence of Mycoplasma pneumonia is higher in regions with temperate climate during the Summer and Fall.

Epidemiology and Demographics

Incidence

• In the USA, the incidence of Mycoplasma pneumonia is approximately 600 per 100,000 individuals.
• It is estimated that approximately 2 million cases of M. pneumoniae infection occur annually and account for approximately 100,000 hospitalizations.
• M. pneumoniae infection accounts for approximately 1 to 10 out of every 50 cases of community-acquired pneumonia.

Age

• Patients younger than 40 years of age are more commonly affected with Mycoplasma pneumonia.
• Mycoplasma pneumonia is especially common among individuals between 5 and 20 years of age.

Gender

• There is no gender predilection to the development of Mycoplasma pneumonia.
• Men may experience a more severe disease compared with women.

Geographical and Seasonal Distribution

• The incidence of Mycoplasma pneumonia is higher in regions with temperate climate.
• The incidence of Mycoplasma pneumonia is higher in Summer and Fall (between June and November).
