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.
The disease was definitively recorded on the continent for the first time in 1647. [1] The Western Hemisphere was then involved in several pandemics during the 1700s, including one in 1761 which, notably, might have begun in North America. [2] [3] Prior to 1789, the last major epidemic of influenza on the continent was in the spring of 1781. [4]
The following is a list of WHO recommended strains for the Northern Hemisphere influenza season. Starting in the 2012–2013 season, the recommendation shifted to include the composition of a quadrivalent influenza vaccine (QIV) that contains both influenza B lineages, alongside a trivalent influenza vaccine (TIV) containing one influenza B lineage.
Pandemic: It’s a scary word. But the world has seen pandemics before, and worse ones, too. Consider the influenza pandemic of 1918, often referred to erroneously as the “Spanish flu ...
The 1889–1890 pandemic, often referred to as the Asiatic flu [57] or Russian flu, killed about 1 million people [58] [59] out of a world population of about 1.5 billion. It was long believed to be caused by an influenza A subtype (most often H2N2), but recent analysis largely brought on by the 2002-2004 SARS outbreak and the COVID-19 pandemic ...

It’s been deemed the worst bird flu outbreak in American history—and the virus is showing no signs of stopping. Since the beginning of this year, nearly 2.5 million birds from commercial and ...
[10] [2] Most commercially available flu vaccines are manufactured by propagation of influenza viruses in embryonated chicken eggs, taking 6–8 months. [2] Flu seasons are different in the northern and southern hemisphere, so the WHO meets twice a year, once for each hemisphere, to discuss which strains should be included based on observation ...
