    The number of SFR cases has risen in the last two decades, from 495 cases in 2000, to a peak of 6,248 in 2017. However, cases reported in 2018 were slightly lower.
    Because of the inability to differentiate between spotted fever group Rickettsia species using commonly available serologic tests, it is unclear how many of those cases are RMSF, and how many resul...
    The number of SFR cases reported to CDC per year have generally increased over time with distinct increases since the mid-1990s.
    Notably, while the number of cases and incidence rose, the case fatality rate (i.e., the proportion of SFR patients that died as a result of infection) has declined since the 1940s when tetracyclin...
    The current case fatality rate for SFRs using surveillance data is still roughly 0.5% of cases.
    Although SFR cases can occur during any month of the year, most cases reported illness in May–August.
    This period coincides with the season when adult Dermacentorticks are most active.
    Seasonal trends may vary depending on the area of the country and tick species involved.
    SFR cases have been reported throughout the contiguous United States, although five states (Arkansas, Missouri, North Carolina, Tennessee, and Virginia) account for over 50% of SFR cases.
    In Arizona, RMSF cases have recently been identified in an area where the disease had not been previously seen. From 2003 to 2018, nearly 430 cases were reported with a case-fatality rate of about 5%.
    SFR cases are more frequently reported in men than in women.
    People over the age of 40 years account for the highest number of reported cases, however, children under 10 years old represent the highest number of reported deaths.
    Persons with glucose-6-phosphate dehydrogenase (G6PD) deficiency.
    Surveillance data shows higher risk for hospitalization in people with compromised immune systems (e.g., resulting from cancer treatments, advanced HIV infection, prior organ transplants, or some m...
