Mycoplasma pneumoniae most commonly affects which age group?

• A. Neonates
• B. Elderly
• C. Teenagers and young adults
• D. Infants

Answer: (C)

Mycoplasma pneumoniae infection shows a pattern where teens and young adults are the most commonly affected. This organism spreads easily in close-contact settings like schools, colleges, and military environments, so outbreaks tend to occur where people interact closely. The illness in this group is often milder and presents as atypical “walking” pneumonia with a dry cough and relatively subtle exam findings, which fits the typical epidemiology of this pathogen. In contrast, pneumonia in neonates and infants is more often due to viruses or other bacteria, and elderly patients are more likely to have pneumonia from pathogens other than Mycoplasma. Thus, the age group most commonly affected is teenagers and young adults.
