2009 H1N1 Flu Pandemic
In June 2009, the World Health Organization declared the H1N1 swine flu a pandemic, the first such declaration in 41 years. Pandemic (H1N1) 2009 is a new virus that has not circulated among humans before. The declaration was made not because the swine flu is particularly dangerous, but because it had become so widespread.

This virus is different from previous or current human seasonal influenza viruses and has also caused severe illness and deaths.
