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.
Future flu pandemics, which may be caused by an influenza virus of avian origin, [35] are viewed as almost inevitable, and increased globalization has made it easier for a pandemic virus to spread, [34] so there are continual efforts to prepare for future pandemics [76] and improve the prevention and treatment of influenza.

The result: “56% of one community-obtained virus was similar to one component of the vaccine and 100% of a second flu virus was similar to a different vaccine component,” Dr. Shah says.
Between the fall of 1789 and the spring of 1790, influenza occurred extensively throughout the United States and North America more broadly. First reported in the southern United States in September, it spread throughout the northern states in October and November, appeared about the same time in the West Indies, and reached as far north as Nova Scotia before the end of 1789.
“The flu virus, like all viruses, is not alive, so it can’t be killed,” says infectious disease expert Amesh A. Adalja, M.D., senior scholar at the Johns Hopkins Center for Health Security ...
