Men have a greater risk of acquiring L pneumophila infection. Older age is another risk factor; the weighted mean age for patients with LD is 52.7 years, with increasing incidence until age 79 years. Mortality rates are also higher in older patients. The incidence of LD in persons younger than 35 years is less than 0.1 cases per 100,000 people.
