Answer

Researchers estimate that more than 2 million cases of M pneumoniae infections occur annually. M pneumoniae causes approximately 20% of community-acquired pneumonias that require hospitalization and an even greater proportion of those that do not require hospitalization. M pneumoniae may exist endemically in large urban areas. Epidemics occur every 3-7 years, with the incidence varying considerably from year to year. Slow spread throughout households is common, with a mean incubation period of 20-23 days. Disease tends to not be seasonal, except for a slight increase in late summer and early fall. [1]
