In Sri Lanka, rickettsial infections have been increasingly reported over the last 2-3 decades, and they include scrub typhus (ST) caused by Orientia tsutsugamushi and spotted fever group rickettsioses [5–7]. Although SFGR was described less commonly in the Western province of Sri Lanka, in a hospital based study where patient recruitment had been on strict inclusion criteria , with the establishment of Indirect Immunofluorescence antibody (IFA) based diagnostics it became apparent that SFGR are as common as scrub typhus (unpublished data). Furthermore, most cases of SFGR present sporadically throughout the year with no seasonal pattern compared to more seasonal outbreaks of ST (unpublished personal observation). Although the organisms causing SFGR in the Western Province of Sri Lanka are yet to be identified, dog ticks are suspected as the most likely vector transmitting the illness based on the reported experiences of patients.
