Here are the steps and topics to work with.

Most importantly start in your own community.  Go to your church and ask them to devote one service to public education.  Ask them what they will be doing at the time of a pandemic and start to organize your local community.  If you belong to a civic group, homeowners or condo association, PTA or even the local Optimist Club, have special meetings. Here is the trick.  We all have networks of other chapters such as Mothers against Drunk Drivers.  The national chapter can notify all local chapters and then they can help educate their own members.
