The Centres for Disease Control and Prevention refutes the claim by stating that the Hantavirus was first detected in 1993.
Other early cases of Hantavirus have been discovered by examining samples of tissue belonging to people who had died of unexplained adult respiratory distress syndrome. The earliest known case of Hantavirus that has been confirmed has been the case of a 38-year-old Utah man in 1959.
