Arne Vidar Røed, also known as Arvid Darre Noe, was a Norwegian sailor and truck driver who contracted one of the earliest confirmed cases of HIV/AIDS. He became the first confirmed HIV case in Europe, with the virus spreading to his wife and youngest daughter. His case marked the first documented cluster of AIDS cases before the early 1980s epidemic. Røed's true identity was concealed for many years, and it was not until after his death that his name became known. His illness began in 1968, and he eventually passed away in 1976, with his wife and daughter also succumbing to similar symptoms. Tests conducted a decade after his death confirmed that all three had tested positive for HIV. It is believed that Røed contracted HIV in Cameroon in the early 1960s, where he was known to have been sexually active with multiple partners. His case sheds light on the early spread of HIV and its impact on individuals outside of the United States.
