Russian flu 1977/1978 - Russische Grippe 1977/1978

As Russian Influenza one is influenza - epidemic called that occurred in 1977 and the 1978th Worldwide it claimed - depending on the source - 500,000–700,000 deaths.

root cause

It was caused by influenza viruses of the subtype A / H1N1 , the subtype that had also caused the Spanish flu in the years after 1918 . This subtype was first isolated in Northern China in May 1977 , and by January 1978 it had spread worldwide. [1] [2]

Children, adolescents and young adults under 25 years of age were primarily affected by the "Russian flu" during which the sick usually only developed mild symptoms. [3] [A 1]

This is attributed by the experts to the fact that A / H1N1 was predominant worldwide from 1918 and was only replaced by the subtype A / H2N2 , the causative agent of Asian flu , in 1957 . Many born before 1957 had therefore already been exposed to this subtype and thus had a certain immune protection , but not those born after 1957. Since the wave of the disease was limited to young people, it is usually not classified as a pandemic .

The subtype A / H1N1 of the "Russian flu" was so similar to the subtype from the years before 1957 that the suspicion quickly arose that the virus had escaped from a Soviet or Chinese laboratory in the mid-1970s . [4] The small number of deviations ( mutations ) in his genome can only be explained by the fact that the virus had literally been frozen for decades. This thesis was also represented in 1992 [5] by the renowned influenza researcher [6] Robert Webster .

The H1N1 genome of the "Spanish flu" was reconstructed in 2005 by a working group led by Jeffery Taubenberger . [7]

The Russian flu of 1889/1890 was caused by a different subtype.
