The 4,572 cases reported 1988 represent a ninefold increase since 1982, when national surveillance was established, and doubling of over previous year (2,368 were 1987). has spread from its original geographic focus northeast to include 43 states, with marked regional differences incidence rates. New York state alone 56% all 1988. Six northeastern states (New York, jersey, Connecticut, Pemisylvania, Rhode Island, Massachusetts) accounted for 80% nation's 1987 These addition Wisconsin, Minnesota, California, collectively account 95% 1987-1988. A preliminary analysis indicates that Pacific primarily occur broader range months different age distribution than other regions. Differences tick vector species, their rates infection, ecology may be reflected risk epidemiologic patterns disease.
