Student dies of scrub typhus after 4 days of fever: Key warning signs

A 20-year-old Anna University student died after just four days of fever from scrub typhus, highlighting the importance of recognizing this often-misdiagnosed infection. Initially presenting with high fever, the student's condition rapidly deteriorated, leading to disorientation, confusion, and altered mental state before he was admitted to a government hospital. Doctors found no sign of dengue but confirmed scrub typhus, which had caused respiratory distress and multi-organ failure.

Scrub typhus, caused by bacteria Orientia tsutsugamushi transmitted by infected mites, can mimic other fever-causing illnesses like dengue, malaria, and leptospirosis, making early diagnosis crucial. Symptoms include fever, headache, muscle aches, and a possible scab-like lesion at the bite site, though not all patients develop this.

Doctors should consider scrub typhus, especially in rural or peri-urban environments with mite habitats, and assess symptoms such as deterioration, recent vegetation exposure, and organ involvement.

Early treatment with doxycycline is recommended if scrub typhus is suspected, even before laboratory confirmation. Complications like ARDS, renal failure, meningo-encephalitis, and multi-organ dysfunction can be life-threatening, requiring urgent referral to specialized centers.
