Introduction:-
Scrub typhus is a zoonotic rickettsiosis caused by the bacterium Orientia tsutsugamushi. It is transmitted by larvae of the Leptotrombidium mites and is endemic to a region called the tsutsugamushi triangle that extends from Southeast Asia to the Pacific Ocean 1. Scrub typhus commonly infects farmers and field workers 1. The central nervous system (CNS) can often be affected in scrub typhus, with neurological manifestations being present in approximately 20% of cases, either in the form of acute encephalitis, meningitis, or meningoencephalitis2. The clinical manifestations of scrub typhus are variable, with the involvement of nearly every system and organ, alone or in combination 3. Recent epidemiological studies suggest that scrub typhus is a major cause of central nervous system infections in endemic areas 4–6. The neurological manifestation of scrub typhus has become an emerging public health concern beyond current endemic areas, as ecological changes may increase the prevalence of arthropod-borne CNS-infected populations worldwide7. On the other hand, delayed treatment can lead to significant neurological creaks and even death 8.
