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. The virus was first identified in Guizhou. It spread to Singapore in February 1957, reached Hong Kong by April, and US by June. Death toll in the US was approximately 69,800. Estimates of worldwide deaths caused by this pandemic varies widely depending on source; ranging from 1 million to 4 million, with WHO settling on "about 2 million". Asian Flu was of the H2N2 subtype (a notation that refers to the configuration of the hemagglutinin and neuraminidase proteins in the virus) of type A influenza, and an influenza vaccine was developed in 1957 to contain its outbreak. The Asian Flu strain later evolved via antigenic shift into H3N2 which caused a milder pandemic from 1968 to 1969. Both the H2N2 and H3N2 pandemic strains contained avian influenza virus RNA segments. "While the pandemic human influenza viruses of 1957 (H2N2) and 1968 (H3N2) clearly arose through reassortment between human and avian viruses, the influenza virus causing the 'Spanish flu' in 1918 appears to be entirely derived from an avian source (Belshe 2005)."

What was the panic of 1957?
Asian Flu Pandemic of 1957-58
In what year did the bird flu pandemic happen?
The bird flu pandemic has happened 4 times in recorded human history. It has occurred in 1918, 1957 as the Asian flu, 1968 in Hong Kong, and in 2009 as the swine flu.
When did the swine flu enter Maine?
In early 2009 at the start of the pandemic.
What questions must scientist answer to fully understand the 1918 flu pandemic?
Is it a the flu epidemic or flu pandemic
Did the Swine Flu start from Japan?
No, the 2009 pandemic swine flu (A-H1N1/09) is thought to have begun in Mexico. The types of flu that mutated to become this pandemic flu do include one of the Asian forms of the H1N1 that pigs get, but the location of the first cases of H1N1/09 was Mexico. See the related questions for more information.
If you had H2N2 flu in 1957 do you need H1N1 shot?
Yes. There has never been a vaccine made for a strain that was close enough to the current H1N1/09 pandemic flu to have allowed our immune systems to make antibodies that would be a good fit to the new flu. So, no prior vaccinations will have provided any protection for the pandemic swine flu. When you can get an H1N1/09 flu vaccination, you should go ahead and get one to be protected.
What are the effects of a flu pandemic?
the effects of a flu pandemic don't need to be lethal because the meaning of the word pandemic is that the disease is spreading fast on a global scale.
What was the worst pandemic?
The 1918 pandemic of the Spanish Flu killed multiple millions world wide.
What is a pandemic flu?
Pandemic Flu Pandemic refers to contagious or infectious diseases that are usually worldwide or spread across several continents. Some examples of diseases that have caused past pandemics would be cholera, small pox, the bubonic plague, typhus, the Spanish flu, and the Asian flu. Flu refers to influenza. Human influenza pandemics, such as the 2009 novel swine flu (A-H1N1/09) pandemic, are caused by the influenza virus subtypes of A-H1N1. A-H1N1/09 is the subtype that caused this recent swine flu pandemic. It was declared a pandemic on June 11, 2009 by WHO (World Health Organisation).
