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 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 ...
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.

Each year flu related complications in the USA affect close to 100,000 asthmatics, and millions more are seen in the emergency room because of severe shortness of breath. The CDC recommends that asthmatics are vaccinated between October and November, before the peak of the flu season. Flu vaccines take about two weeks to become effective. [28]
Cases disproportionately occur in children, but most severe causes are among the elderly, the very young, [1] and the immunocompromised. [4] In a typical year, influenza viruses infect 5–15% of the global population, [3] [62] causing 3–5 million cases of severe illness annually [1] [2] and accounting for 290,000–650,000 deaths each year ...
The 1889–1890 pandemic, often referred to as the "Asiatic flu" [1] or "Russian flu", was a worldwide respiratory viral pandemic. It was the last great pandemic of the 19th century, and is among the deadliest pandemics in history. [2] [3] The pandemic killed about 1 million people out of a world population of about 1.5 billion (0.067% of ...
