USPHS

The United States Public Health Service (USPHS) Commissioned Corps, established in 1889, is one of the eight uniformed services of the United States. Originally formed to provide medical care to merchant seamen, the USPHS rapidly expanded its mission to protect, promote, and advance the health and safety of the nation. USPHS officers have served alongside the military in every major conflict since World War I, providing critical medical, research, and public health support. Today, the USPHS Commissioned Corps responds to public health emergencies, disease outbreaks, and natural disasters both domestically and internationally.
