Created in May, 2015, by Centers for Disease Control and Prevention (CDC), Epidemiologist, Caitlin M. Worrell, M.P.H., this image depicts a collection of dried blood samples, obtained from school children in Haiti, as part of a transmission assessment survey (TAS), being carried out in the Dondon Commune in Northern Haiti. The results of such surveys allows the national program to determine if mass drug administration has been successful in reducing the prevalence of lymphatic filariasis (LF). This was one of the entries in the 2015 CDC Connects, Public Health in Action Photo Contest.
Lymphatic filariasis (LF), more commonly known as elephantiasis, is a disfiguring parasitic disease. Globally, approximately 1.34 billion people are at risk for contracting LF and developing the disfiguring physical manifestations associated with this disease. Through mass drug administration the global community has made great progress towards eliminating LF as a public health problem. Further, the elimination of LF in the Americas is a CDC winnable battle. In support of this, CDC has partnered with the Haiti Ministry of Public Health and Population (Ministere de la Sante Publique et de la Population) and local NGOs, to support mass drug administration and provide technical assistance for impact evaluations, known as transmission assessment surveys (TAS).
