Data from: Burden of scrub typhus among patients with acute febrile illness attending tertiary care hospital in Chitwan, Nepal
Description
Objectives: Scrub typhus is an emerging neglected tropical disease, reported from many parts of Asia including Nepal. This study aims to determine the seroepidemiology of scrub typhus among febrile patients attending Chitwan Medical College Teaching Hospital (CMCTH), Bharatpur, Nepal.
Study design and setting: This was a hospital laboratory based prospective study conducted in CMC-TH (a 600-bed hospital) located in Bharatpur, Chitwan district of Nepal.
Participants: A total of 1797 patients visiting CMC-TH with acute febrile illness (temperature more than 380C) were enrolled in this study.
Methods: A total of 1797 blood samples were collected from patients presenting with acute febrile illness. The samples were processed for detection of antibody for scrub typhus by Enzyme Linked Immunosorbent Assay (ELISA) for specific immunoglobulin M (IgM) antibody and Weil-Felix test.
Results: Out of 1797 serum sample of febrile patients, 524 (29.2%) were scrub typhus positive. Maximum seropositive cases were from Chitwan district 271 (51.7%) with predominance among females 314 (35.9%). Scrub typhus was common among age group 51-60 years (37.2%) and farmers 182 (37.8%). Highest seropositivity was found in July 60 (57.7%). Fever was common clinical symptom. Thrombocytopenia was seen in 386 (73.7%) and raised transaminase AST 399 (76.1%) among seropositive cases. Weil-Felix test positive were 397 (22.1%) and IgM ELISA 524 (29.2%). The correlation between IgM ELISA and Weil-Felix test showed statistically significant association (r = 0.319, p<0.001).
Conclusion: High prevalence of scrub typhus implies that acute febrile patients should be investigated for scrub typhus with high priority. There is utmost need of reliable diagnostic facilities at all level of health care system in Nepal. Infection with scrub typhus was found high and this calls for an urgent need to introduce vaccine against scrub typhus. More sustain and vigorous awareness programs need to be promoted for early diagnosis, treatment and control.
