Infections account for many of the illnesses encountered by older adults.; Early detection such as fever and an increase in white cell counts are frequently absent. A change in mental status or decline in function may be the only presenting problem in an older individual with an infection. Mortality resulting from influenza also occurs primarily in the elderly. Urinary tract infections are the most common cause of bacteremia in older adults.
