As climates warm, disease carrying life expands its range. Many diseases are confined to the tropics because their carriers can’t survive freezes, or even cold. There’s a continuum that includes carriers that can survive winters as long as they are short or not severe. As climates warm, their ranges grow, and they diseases spread. Lyme disease has tripled from 10,000 cases to 30,000 cases in less than twenty years. Mosquitoes have greater range. So do jellyfish. Medical professionals require updated training as new diseases enter their area. The response to a symptom may change. Individuals also must learn the need for tactics familiar to their more tropical neighbors, eliminating standing water, etc. Even local wildlife will shift as they, too may be vulnerable.
