Influenza pandemic
The 1977 Russian flu was an influenza pandemic that was first reported by the Soviet Union in 1977 and lasted until 1979.[ 1] [ 2] The outbreak in northern China started in May 1977, slightly earlier than that in the Soviet Union.[ 3] [ 4] The pandemic mostly affected a population younger than 25 or 26 years of age,[ 1] [ 5] [ 6] and was described as mild.[ 6] It was caused by an H1N1 flu strain which highly resembled a virus strain circulating worldwide from 1946 to 1957.[ 1] [ 2] [ 5] [ 6] 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,[ 4] [ 5] [ 7] [ 8] [ 9] [ 10] or resulted from a live-vaccine trial escape.[ 5] [ 11]
