This is a prospective funding opportunity awarded by the Epidemiology and Laboratory Capacity for Prevention and Control of Emerging Infectious Diseases (ELC) grant program designed to protect the public health and safety of the American people by enhancing the capacity of public health agencies to effectively detect, respond, prevent, and control known and emerging (or re-emerging) infectious disease. In an effort to address emerging infectious diseases, ELC has incorporated Program K: Vector-borne diseases into the grant program. The purpose of this program is to support state and local health departments to implement and maintain accurate and relevant surveillance for human disease and their vectors, improve laboratory practices and capacity, and to implement and evaluate prevention strategies. This program comprises all vector-borne surveillance and control activities related to a subset of vector-associated diseases.
