What is scrub typhus?

Scrub typhus is an infectious disease caused by bacteria called Orientia tsutsugamushi. It is transmitted to humans through the bites of infected larval mites, known as chiggers. Scrub typhus is commonly found in rural areas of Southeast Asia, Japan, China, India, and northern Australia.

Symptoms of scrub typhus typically develop within 10-12 days after the bite of an infected chigger. These symptoms may include:

1. Fever: High fever (up to 105°F) is a hallmark symptom of scrub typhus.

2. Headache: Severe headaches are common.

3. Muscle Pain: Aching and pain in the muscles, especially in the legs and back, are frequently experienced.

4. Rash: A characteristic rash often develops on the trunk, arms, and legs. It initially appears as small, red spots that can become larger and merge to form a solid red patch.

5. Swollen Lymph Nodes: The lymph nodes closest to the bite or the affected area may become enlarged and tender.

6. Chills: Chills and shivering may accompany the fever.

7. Cough: A dry cough is sometimes present.

8. Gastrointestinal Symptoms: Nausea, vomiting, and abdominal pain may occur.

9. Confusion and Disorientation: In severe cases, confusion and disorientation may develop.

It's important to seek medical attention promptly if you develop a fever and any of the symptoms mentioned above, especially if you have recently been in an area where scrub typhus is known to occur. Early diagnosis and treatment can significantly improve the outcome of the infection.
