Abstract

Introduction: Scrub typhus, caused by Orientia tsutsugamushi and transmitted by bite of larval trombiculid mite of the Leptotrombidium genus and is a vector borne zoonotic disease. It has been predominantly reported from Southeast Asia, the Asian Pacific Rim, and Australia. The incidence of this disease is increased in India. These patients show an acute undifferentiated febrile illness and laboratory confirmation is essential. Delay in diagnosis may be fatal.
Aim : To assess the Scrub typhus burden among acute febrile illness patients.
Materials and Methods: This Cross-sectional study, conducted in Dept. of Microbiology, Basaveshwara Medical College & Hospital, Chitradurga, Karnataka, India. Study duration was from August 2020 to January 2021. In this study, a total of 100 febrile illness patients were involved. Among them, 66 were males and 34 females. Under aseptic conditions, venous blood samples were collected from all subjects. Serum was separated by centrifugation, aliquoted, and stored at ?20°C for further testing. The serum sample was tested for scrub typhus IgM ELISA using the INBIOS kit. Samples were also checked for dengue fever, typhoid fever, leptospirosis, and malaria. The serum samples that tested positive for any other infectious disease mentioned above (with or without detectable rickettsial antibodies) were excluded from the study. Data was represented in numbers and percentages.
Results : In this study, out of 100 samples 30 were seropositive. Of the 30 seropositive scrub typhus cases, women were 11 (37%) and men were 19 (63%), suggesting that seropositivity was more in men than women. Among the seropositive cases, maximum number of the cases were in 16-30 years (33%) of age, followed by 31–45 years (23%). In this study, more number of positive cases 17 (56.6%) were found during the post-monsoon season i.e., October and November 2020. Fever, the most common symptom (100%). Headache, reported in (70 %) of cases, myalgia (40%), abdominal pain (37%), cough (23%), vomiting (20%), lymphadenopathy (17%), rashes (13%), hepato-spleenomegaly (10%), eschar (3%).
Conclusion: The study results may conclude that Scrub typhus seropositivity rate was higher in males than females and also to be included in differential diagnosis of fever of unknown origin.
