Summary

Scrub typhus is a disease caused by a bacteria called Orientia tsutsugamushi and transmitted to people through bites of infected chiggers (larval mites). After the 2015 Gorkha earthquake in Nepal, a sudden upsurge in scrub typhus cases was reported with repeated outbreaks from different parts of the country. This study has documented epidemiology of scrub typhus and its causative agents in human, rodent and chigger mites confirming the local transmission O. tsutsugamushi with a firmly established ecology in Nepal. The local transmission of the diseases from most parts of the country demands strengthening for systematic surveillance, early outbreaks detection, and immediate response actions including treatment and preventive measures.
