mycoplasma pneumonia

Last reviewed 01/2018

Mycoplasma pneumonia is implicated in about 6% of pneumonias in the UK (1).

Infection occurs in 3 to 4 year cycles in temperate climates and chiefly affects children and young adults, causing an atypical pneumonia characterised by an influenza-like respiratory illness of gradual onset with headache, malaise, fever and cough (2).

Physical findings may be insignificant relative to the radiologic appearance of the pneumonia; some individuals are asymptomatic. Close indoor contact facilitates spread.
