The iTunes app store contains numerous apps that promise to help you track the H1N1 virus, better known to many as the cause of rapidly spreading Swine Flu. It is a worldwide pandemic President Obama recently declared a national emergency. One of the latest apps to address H1N1 is from Harvard Health Publications (a division of Harvard Medical School).

Aptly called The Swine Flu app ($1.99, available here), the application includes science-based information (via videos, animations, text and realtime updates) on the state of the pandemic's spread; practical steps people can take to mitigate their risk of infection; key symptoms to watch for; and how to act in case of a suspected infection. In addition, the application provides businesses with specific information on how to best prepare their enterprises for managing through the pandemic.

Harvard's H1N1 app is the first in series of iPhone applications called HMS Mobile that promises to promote public health.
