Since the introduction of Hib conjugate vaccines, the incidence of invasive disease caused by H. influenzae in the United States has decreased dramatically; however, a considerable burden of non-Hib disease is still present in the oldest and youngest age groups. There is no evidence of substantial replacement disease with non-b serotypes in young children in the United States.

Public health workforce development efforts during the past 50 years have evolved from a focus on enumerating workers to comprehensive strategies that address workforce size and composition, training, recruitment and retention, effectiveness, and expected competencies in public health practice. We provide new perspectives on the public health workforce, using data from the Public Health Workforce Interests and Needs Survey, the largest nationally representative survey of the governmental public health workforce in the United States. Five major thematic areas are explored: workforce diversity in a changing demographic environment; challenges of an aging workforce, including impending retirements and the need for succession planning; workers’ salaries and challenges of recruiting new staff; the growth of undergraduate public health education and what this means for the future public health workforce; and workers’ awareness and perceptions of national trends in the field. We discussed implications for policy and practice.
