I am not saying CFS is a tick disease but the following really makes me wonder: There are many reasons suggesting the infectious etiology and, more specifically, Rickettsial-like organisms of CFS. Amongst those reasons: 1. Consider the following : - CFS was first reported in Incline, Nevada in 1984 (1) and developed into epidemic proportions. - Rocky Mountain Spotted Fever originated from the same place in 1916. I guess it could be coincidense, add the fact that there is a very high amount of W. Black Legged Ticks in this area.
