The 1957 influenza pandemic (the "Asian flu") was one of the famous influenza pandemics in history.The "Asian Flu" was a category 2 flu pandemic outbreak of avian influenza that originated in China in early 1956 lasting until 1958. It originated from mutation in wild ducks combining with a pre-existing human strain.
Date. February 1957-1958 (Possible 1959) The 1957-58 influenza pandemic, also called Asian flu was a time when many people caught H2N2 influenza A and became sick. Westerners first learned about this influenza when it was in Singapore. It killed 1.1 million people.
In February 1957, a new influenza A (H2N2) virus emerged in East Asia, triggering a pandemic (“Asian Flu”). This H2N2 virus was comprised of three different genes from an H2N2 virus that originated from an avian influenza A virus, including the H2 hemagglutinin and the N2 neuraminidase genes. It was first reported in Singapore in February ...
Some immunity against the N2 flu virus may have been retained in populations struck by the Asian Flu strains that had been circulating since 1957. The pandemic did not gain momentum until near the winter school holidays in the Northern Hemisphere, thus limiting the infection's spread. Improved medical care gave vital support to the very ill.
Outbreaks. See also. v. t. e. Avian influenza, also known as avian flu, is a bird flu caused by the influenza A virus, which can infect people. [note 1] It is similar to other types of animal flu in that it is caused by a virus strain that has adapted to a specific host. The type with the greatest risk is highly pathogenic avian influenza (HPAI).
Influenza viruses which have undergone antigenic shift have caused the Asian Flu pandemic of 1957, the Hong Kong Flu pandemic of 1968, and the Swine Flu scare of 1976. Until recently, such combinations were believed to have caused the infamous Spanish flu outbreak of 1918 which killed 40~100 million people worldwide.
The pandemic of 1957-58 ultimately caused 1.1 million deaths worldwide, and it follows the 1918 crisis as the second-most severe influenza outbreak in U.S. history. Some 20 million Americans were ...
