Cholera vaccination in Vietnam. US Navy hospital worker in 1966 inoculating a flood refugee against cholera at a refugee centre on Nui Sam mountain, Chau Doc province, Vietnam. Cholera is a bacterial infection of the small intestine that is transmitted via contaminated food or water. The bacterium produces a toxin that causes diarrhoea and severe dehydration, which may be fatal if left untreated. The worker is part of a USAID (United States Agency for International Development) military health team operating in Vietnam. This health aid is being provided during the Vietnam War (1955-1975).
