National Center for Infectious Diseases, Division of Viral and Rickettsial Diseases, The Centers for Disease Control and Prevention, Atlanta, GA 30333, USA
N Engl J Med 353:587-94. 2005..This disease is rarely reported in Arizona, and the principal vectors, Dermacentor species ticks, are uncommon in the state.

Centers for Disease Control and Prevention, National Center for Infectious Diseases, Division of Viral and Rickettsial Diseases, Atlanta, Georgia, USA
Vector Borne Zoonotic Dis 6:423-9. 2006..In comparison, only 5% of canine samples from 1996 had anti-R. rickettsii antibodies at titers > or = 32. These results suggest that exposures to RMSF have increased over the past 9 years, and that RMSF may now be endemic in this region... - Human monocytic ehrlichiosis and human granulocytic anaplasmosis in the United States, 2001-2002Linda J Demma

Scrub typhus, Republic of PalauLinda J Demma
Centers for Disease Control and Prevention, Atlanta, Georgia 30333, USA
Emerg Infect Dis 12:290-5. 2006..Sera collected from rodents (Rattus norvegicus and R. rattus) in 2003 and 2005 were tested, and 18 (28.6%) of 63 had IgG antibody titers >1:64. These findings suggest that scrub typhus is endemic in Palau...- Rocky mountain spotted fever in the United States, 1997-2002Alice S Chapman
