Figure

Figure. Evidence of rickettsiosis or scrub typhus among US military personnel deployed to South Korea. Black bars indicate postdeployment serum samples from US military personnel with a titer ≥1:100 (seropositive) to typhus group rickettsiae (TGR), spotted fever group rickettsiae (SFGR), or scrub typhus group orientia (STGO) IgG, as determined by ELISA. White bars indicate personnel determined by paired serum sample analyses to have seroconversion or 4-fold rise in titer between predeployment and postdeployment serum samples, indicating evidence of infection with the corresponding pathogen during deployment.
