H1N1

In April of 2009, Mexico aknowledged an H1N1 outbreak that had been going on for months in the Mexican state of Veracruz. The World Health Organization got involved as the disease spread globally.In June of 2009, the WHO and CDC declared the outbreak a pandemic. The virus began to decline in November of 2009, and in May of 2010, it declined even more rapidly. Then, on August 10, 2010, Margaret Chan, the Director-General of the WHO declared the pandemic had ended.



Over the course of the pandemic, 18,000 deaths were reported, but due to unconfirmed and unreported cases, and the few months prior to the declaration of an outbreak,the actual number of deaths was higher than that. The mortality rate was between 0.01% and 0.03%, and the global infection rate was approximately 11% to 21%.

Here are some maps that show the number of confirmed cases and deaths all over the world:
