Advanced age is associated not only with a higher incidence of CAP but also with more severe disease, greater need for hospitalization, and higher mortality. [25, 45]

CAP encountered in the ambulatory setting is more common among young adults and is usually due to so-called atypical CAP pathogens (eg, Mycoplasma pneumoniae). [46]
