The Pandemic Flu Survival Guide, from Stephenson Strategies http://stephensonstrategies.com was recently released and is available for only $9.95 (including updates) from mobile content web sites, including PocketDirectory.com.

It is available for Palm and Microsoft Windows handhelds and smartphones. It was developed by Homeland security strategist and planning expert W. David Stephenson who complied vital and current information from the World Health Organization (WHO), the U.S. Centers for Disease Control (CDC), the US pandemicflu.gov web site, the UK Health Protection Agency, and it is supplemented by material from other sources.
The data is compressed into more than 150 listings in 6 categories: sources for latest information, preparations, staying healthy, travel precautions, the illness and its treatment, and human & economic impacts. The information ranges from checklists for family medical and food supplies to an extensive set of business continuity recommendations.

E-mail and/or RSS feeds notify subscribers of updates as the changing situation dictates.

While $9.95 is very reasonable for a handheld medical program, don't forget there are some quality free resources as well.
