2009 A/H1N1 Pandemic (initially called “Swine Flu”) During 2009, a substantially different strain of the H1N1 influenza virus was transmitted to humans. It was thought that some older populations were thought to have some immunity directly or via cross- protection from earlier flus. However, since most humans did not have immunity to the virus, the result was pandemic. In the initial stages of the pandemic, it was sometimes referred to as Swine Flu. Using Figure 2, answer the following questions regarding the 2009 A/H1N1 Pandemic.
