    nationally reportable disease in the United States since the 19 40’s. Cases reported in other parts of the United States occur most commonly from May to August, with the peak activity occurring in June and July. The highest incidence rate is observed in individuals 55 to 64 years of age.

    Rocky Mountain spotted fever was first discovered in the Snake River Valley of Idaho in 1896. It was frequently fatal and many people in the region got sick. By 1900, it had been found in Washington, Arizona, and New Mexico. Today it is found throughout the United States, Canada, Mexico, and South America.

    At the moment, there are around 326 million people living in the United States, a country that’s 3.5 million square miles (9.8 million sq km) in land area. But throughout the nation’s history, neither of these numbers have stayed constant.

    In 1937, Parker et al. identified a unique spotted fever rickettsia borne by the Gulf Coast tick (A. maculatum) (figure 1A); this rickettsia was eventually named Rickettsia parkeri in Parker's honor. When these investigators infected guinea pigs with R. parkeri, they observed a febrile illness in the animals that was similar to but milder than Rocky Mountain spotted fever (RMSF) , which led Parker and others to speculate that R. parkeri might also cause an RMSF-like disease in humans. In 200...

    Patients. Serum, whole blood, and skin biopsy specimens are routinely submitted to the Centers for Disease Control and Prevention (CDC) by clinicians and state health departments for specialized diagnostic tests when a spotted fever rickettsiosis is suspected in patients with compatible clinical signs and epidemiologic features. For patients residing within the US range of A. maculatum endemicity for whom an eschar or vesicular rash was reported to the CDC during 1998–2007, specimens were eva...

    Patient characteristics. Six confirmed and 6 probable cases of R. parkeri rickettsiosis were identified in patients from Alabama, Florida, Kentucky, Maryland, Mississippi, South Carolina, and Virginia during 1998–2007 (figure 1 and table 1). Patients (8 men and 4 women) had an age range of 23–83 years (median age, 53 years). Ten patients (83%) became ill between late July and early September. Seven patients reported a tick bite, and eschars were identified definitively at bite sites for 6 pat...

    During 1998–2007, we identified 6 confirmed and 6 probable cases of R. parkeri rickettsiosis by passive surveillance of specimen submission to the CDC for diagnostic assays. Cases occurred across a wide geographic region that approximated the US distribution of A. maculatum. The probable cases were identified by assays specific only to the level of SFGR; however, other supportive data strongly suggest that each of the patients with probable cases was infected with R. parkeri. All had a relati...
