During the 1918 Spanish flu pandemic, this practice served to promote the evolution of more virulent viral strains over those that produced mild illness.) When it first killed humans in Asia in the 1990s, a deadly avian strain of H5N1 posed a great risk for a new influenza pandemic; however, this virus did not mutate to spread easily between ...
The "Asian Flu" was a category 2 flu pandemic outbreak of influenzavirus A that first appeared in Guizhou, China in early 1957 and lasted until 1958.

This is a timeline of influenza, briefly describing major events such as outbreaks, epidemics, pandemics, discoveries and developments of vaccines.In addition to specific year/period-related events, there is the seasonal flu that kills between 250,000 and 500,000 people every year and has claimed between 340 million and 1 billion human lives throughout history.
Following the pandemic, seasonal influenza occurred, with subsequent pandemics in 1557 and 1580. [72] The flu pandemic in 1557 was potentially the first time influenza was connected to miscarriage and death of pregnant women. [76] The 1580 influenza pandemic originated in Asia during summer, spread to Africa, then Europe, and finally America. [68]
Due to a lack of laboratory facilities, the exact cause could not be identified, but the disease was considered to represent pandemic influenza. [123] Cases increased again in late July 1969. After a brief decrease, cases again increased until the week ending 4 October, when they then declined. Serology tests at this time indicated pandemic ...
