Epidemiology, Clinical Presentation, Lab Diagnosis and Outcome of Scrub Typhus Outbreak in a Tertiary Care Center in Southern Rajasthan.

Scrub typhus is also known as tsutsugamushi disease or bush typhus. It is a mite-borne acute febrile illness caused by Gram-negative intracellular organism called Orientia tsutsugamushi, which belongs to the family of Rickettsiaceae. The aims and objectives are to study the epidemiological patterns, different clinical manifestations and complications associated with scrub typhus. This was a prospective study which was carried out over a period of 12 months from January 2019 to December 2019 in patients of scrub typhus admitted in various medical wards of MB Govt. Hospital and RNT Medical College, Udaipur, Rajasthan. All the patients admitted with history of acute febrile illness suspected to be scrub typhus were assessed in the study. All these patients were evaluated by the set protocol in the form of detailed history, physical examination and relevant systemic examination. A total of 3,814 suspected patients of scrub typhus were tested in our microbiology laboratory and 1,340 patients were reported positive. Out of these, only 480 patients who were admitted in our medical wards were enrolled in our study and evaluated. We conclude that in rural Rajasthan, any patient who presents with fever, myalgia, hepatosplenomegaly and multiorgan dysfunction syndrome, a diagnosis of scrub typhus should be suspected.
