What are Some Historical Examples of Zoonotic Spillover?
Several major infectious diseases have originated from zoonotic spillover. For example, the Spanish Flu of 1918 is believed to have originated from avian species, while the H1N1 pandemic in 2009 was linked to a combination of human, swine, and avian influenza viruses. More recently, the SARS and MERS outbreaks have been traced back to bats and camels, respectively.
