Scrub typhus and leptospirosis in rural and urban settings of central India: a preliminary evaluation

Abstract

Scrub typhus and leptospirosis are bacterial zoonotic diseases reported from different parts of India, whose prevalence in Chhattisgarh is unknown. Our study was carried out to delineate the prevalence of these illnesses there and to assess the clinical profiles of rural and urban patients. A total of 169 patients with acute febrile illnesses (AFI) was enrolled in our study from May to December 2018, of whom 35 (20.7%) tested positive for scrub typhus and only one tested positive for leptospirosis by respective IgM ELISA. Scrub typhus seropositivity was higher in rural patients (25.0%) than in urban (18.1%). Patients in the age group 16-30 years were the most commonly affected. The commonest presenting symptoms were fever with headache (68.57%), extreme weakness (57.14%), myalgia/arthralgia (54.29%) and abdominal pain (51.43%). The preliminary evidence for the presence of scrub typhus in Chhattisgarh necessitates its inclusion in the panel of tests for AFI.
