The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919.
How long did Spanish flu last in the world?
The influenza pandemic of 1918–19, also called the Spanish flu, lasted between one and two years. The pandemic occurred in three waves, though not simultaneously around the globe.
What killed the Spanish flu?
The majority of deaths were from bacterial pneumonia, a common secondary infection associated with influenza. This pneumonia was itself caused by common upper respiratory-tract bacteria, which were able to get into the lungs via the damaged bronchial tubes of the victims.
Where did Spanish flu start?
While it's unlikely that the “Spanish Flu” originated in Spain, scientists are still unsure of its source. France, China and Britain have all been suggested as the potential birthplace of the virus, as has the United States, where the first known case was reported at a military base in Kansas on Ma.
What animal did the Spanish flu come from?
Presented data support the hypothesis that the 1918 pandemic influenza virus was able to infect and replicate in swine, causing a respiratory disease, and that the virus was likely introduced into the pig population during the 1918 pandemic, resulting in the current lineage of the classical H1N1 swine influenza viruses ...
