📖What is Scrub Typhus?
Scrub Typhus is an acute infectious disease caused by the bacterium Orientia tsutsugamushi, transmitted to humans through the bite of infected chigger mites found in areas with dense vegetation. The disease is characterized by high fever, a distinctive black scab called an eschar at the bite site, and can progress to severe multi-organ complications if untreated. It is endemic to rural and semi-rural parts of Asia, including many regions of India, particularly during and after the monsoon season. Early antibiotic treatment is highly effective and dramatically reduces the risk of severe complications.
