Molecular Assay Versus Serology for Diagnosis of Scrub Typhus Among Patients With Acute Febrile Illness: A Retrospective Study

The study participants had symptoms like fever, cough, lymphadenopathy, rash, pain in the abdomen, and eschar. Our findings suggest that ELISA and DNA RT-PCR could be used for scrub typhus diagnosis among patients with febrile illness for > 5 and ≤ 5 days, respectively. Both diagnostic methods were found to possess a positive correlation. The findings of ELISA and DNA RT-PCR must be probed further.
