Testing for spotted fever group rickettsioses (SFGR) signs (eschar or rash) were found in 87% of SFGR and the criteria for identifying suspected patients are patients; 79% had a rash, 48% had an eschar, and not routinely used in Kazakhstan. In 2019, we per- 13% had neither. Testing of suspected rickettsia casformed a cross-sectional study in 6 sentinel hospitals es resulted in a 27% increase in laboratory-detected in the Pavlodar region. We tested 105 hospitalized pa- SFGR over the mean of the previous 3 years (62 vs. tients with SFGR-like symptoms by using PCR or indi- 49). Broadening the case definition by including fever, rect immunofluorescence antibody assay and identified headache, or myalgia and expanding routine testing for 62 cases of SFGR. Most (78%) cases of disease were suspected cases of SFGR could contribute to improved caused by Rickettsia sibirica and R. raoultii. Cutaneous case detection and earlier treatment.
