What are other examples of pandemics?

Perhaps the most well-known and devastating pandemic is that of human immunodeficiency virus (HIV), which causes acquired immunodeficiency syndrome (AIDS). Another well-known pandemic is the 1918 flu, also known as the Spanish flu, which killed between 40-50 million people.

In 1957, Asian influenza killed 2 million people, and in 1968, Hong Kong influenza killed 1 million people.
