I can't tell you all the  preventative health care that is done in this state due to the dedication of the staff of Alaska Public Health. First check out the State of Alaska Department of Public Health website. Then go visit them or give them a call, I am sure they can help you learn what you do not know.  I will mention that Alaska is a rural state and that a lot of their health care comes from Public Health and the wonderful visiting nurses, you recall them back in the day when they were in your neighborhood with their black bag, well,  Alaska's Public health Nurses are still doing their thing. I knew one Alaska Public Health Nurse who flew her own Cessna on the job to visit the remote villages. I came to Alaska in the 1970's to be a Bush nurse but my calling was not there. One of my most memorable experiences was the H1N1 Flu epidemic nationwide. Public Health in Alaska had a mass campaign to get people to wash their hands and that they did.
