Spanish Flu (Influenza A Virus H1N1)
100th Anniversary of the
Spanish Flu (1918 - 2018)
There were four influenza pandemics in the last century. The 1918 Spanish flu was the mother of all pandemics in two ways: it was the deadliest, and, remnants of that viral strain led to the other outbreaks.
In a typical flu season up to 500,000 people will die. The 1918 pandemic sickened up to 40% of the world, killing an estimated 50 million!
