ABSTRACT
Background and Objectives: Scrub typhus is an acute febrile illness transmitted by the bite of trombiculid mite in the larval stage. Scrub typhus is rare in pregnancy and there is paucity of data on the clinical outcome of scrub typhus during pregnancy. Material and Methods: We present five cases of scrub typhus complicating pregnancy who were admitted in the obstetric ward at AIIMS Rishikesh, India during the antenatal period for management. Results: The first patient presented at term pregnancy in semiconscious state while the rest were preterm between 31 and 34 weeks period of gestation. The age at presentation was 21-31 years. All five had febrile illness of >5 days' duration along with cough. Fever investigations like blood culture, peripheral smear for malarial parasite, dengue serology, widal test, and urine culture were negative. Serology for scrub typhus was positive in all. Once diagnosis was confirmed for scrub typhus, patients were given the drug of choice azithromycin 500 mg twice daily for five days. Scrub typhus complicating pregnancy led to maternal mortality in one patient. It resulted in one preterm delivery, one intrauterine fetal death, and rest three were delivered at term with good perinatal outcome. Conclusion: Scrub typhus is common in endemic areas like Uttarakhand, India. It has a poor fetal outcome. If diagnosed early and treatment started, maternal and fetal prognosis can be favorable. As large case series are unavailable in literature, it is difficult to predict the course of disease which at times may be fulminant.
