The following data are abstracted from Gideon and the Gideon e-book series.  Charts were created using an interactive tool driven by over 30,000 base graphs in the program. 
Chart 1 contrasts trends for reported incidence of Lyme disease and Rocky Mountain spotted fever (RMSF). Note that while rates of Lyme disease in 2016 are 15-fold those reported in 1987, those of RMSF increased by a factor of seven. The number of fatal cases for both diseases have remained similar in recent years (i.e., the relative case-fatality rate of Lyme disease has decreased)
Chart 2 summarizes incidence data for a variety of tick-borne and mosquito-borne infections. Note that rates of Ehrlichiosis, Anaplasmosis, Babesiosis, Jamestown Canyon virus infection and Powassan encephalitis have increased since the year 2000. The incidence of LaCrosse encephalitis has decreased, while that of California encephalitis is largely unchanged.
Charts 3 and 4 demonstrate that incidence and reported deaths for Western equine encephalitis, Eastern equine encephalitis, St. Louis encephalitis and West Nile fever have changed little in recent years.
