Retrospective analysis of clinico-laboratory parameters, outcome and predictors of scrub typhus co- infection in covid-19 affected children.

The objective of this study was to describe clinico-laboratory parameters, outcome and predictors of scrub typhus co- infection in COVID-19 affected children. Ours was a retrospective analysis done in a tertiary care pediatric COVID facility. COVID-19 positive children in the age group of 1 month to 12 years who were tested for scrub typhus co-infection between May to August 2020 were included in the study. In all positive cases, clinical, laboratory, treatment and outcome data were analyzed. Relevant data were compared between scrub typhus confirmed, and suspected but negative patients. All six patients with co-infection had fever for >5 days and four had features of cerebral involvement. These had lymphocytic pleocytosis in cerebrospinal fluid (CSF) analysis and two had eschar. Screening for scrub typhus in persistently febrile children residing in highly endemic areas is highly recommended.
