The 1977 Russian flu was an influenza epidemic that was first reported by the Soviet Union in 1977 and lasted until 1979. The outbreak in northern China started in May 1977, slightly earlier than that in the Soviet Union. The outbreak mostly affected a population younger than 25 or 26 years of age, and was described as mild. It was caused by an H1N1 flu strain which highly resembled a virus strain circulating worldwide from 1946 to 1957. Genetic analysis and several unusual characteristics of the 1977 Russian flu have prompted many researchers to say that the virus was released to the public through a laboratory accident, or resulted from a live-vaccine trial escape. The World Health Organization, however, ruled out a laboratory origin in 1978 after discussions with researchers in the Soviet Union and China.
