Can scrub typhus cause long-term complications?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

My sister was recently diagnosed with scrub typhus, and I am worried. She has been having a high fever, severe headaches, and body pains. The doctor gave her some antibiotics, but she still seemed weak. We also noticed a black sore near her arm, which I think is the eschar that the doctor mentioned. How long does it take for the antibiotics to start working? Can this condition lead to any long-term damage? Should we be worried about her kidneys or any other organs being affected? Also, how can we make sure no one else in the family gets infected? We have pets at home, could they be carriers of the infection?

Thanks.

Hello,

Welcome to icliniq.com.

I can understand your concern.

Symptoms of scrub typhus usually begin within 10 days after infection. Signs and symptoms include:

  1. Fever and chills.

  2. Headache.

  3. Body aches and muscle pain.

  4. A dark, scab-like region at the site of the chigger bite (also known as eschar).

  5. Mental changes, ranging from confusion to coma.

  6. Enlarged lymph nodes.

  7. Rash.

If not treated appropriately, scrub typhus can be fatal and may lead to organ damage and severe bleeding.

Blood test:

  1. Alkaline phosphatase (ALP): Elevated levels of ALP are common in scrub typhus patients.

  2. Alanine aminotransferase (ALT): Elevated levels of ALT are common in scrub typhus patients.

  3. Aspartate aminotransferase (AST): Elevated levels of AST are common in scrub typhus patients.

Prevention:

  1. No vaccine is available to prevent scrub typhus. Reduce your risk of getting scrub typhus by avoiding contact with infected chiggers. When traveling to areas where scrub typhus is common, avoid areas with lots of vegetation, and brush where chiggers may be found.

  2. Always follow product instructions.

  3. Reapply insect repellent as directed.

  4. Treat clothing and gear with 0.5 percent permethrin or purchase permethrin-treated items.

  5. Permethrin kills chiggers and can be used to treat boots, clothing, and camping gear.

  6. Treated clothing remains protective after multiple washings. See product information to learn how long the protection will last.

  7. If treating items yourself, follow the product instructions carefully.

  8. Do not use permethrin products directly on the skin unless advised by a physician.

Laboratory tests:

  1. PCR (polymerase chain reaction).

  2. ELISA (enzyme-linked immunosorbent assay).

  3. Weil Felix test.

Treatment:

  1. Scrub typhus should be treated with the antibiotic Doxycycline. Doxycycline can be used in persons of any age.

  2. Antibiotics are most effective if given soon after symptoms begin.

  3. People who are treated early with Doxycycline usually recover quickly.

Complications:

  1. Acute respiratory distress syndrome (ARDS) is a severe complication that requires prompt diagnosis and treatment.

  2. Acute kidney injury (AKI).

  3. Myocarditis is a complication that can be life-threatening.

  4. Acute liver failure.

  5. Encephalitis (swelling of brain due to the inflammation).

  6. Pericarditis (inflammation of the pericardium).

  7. Cardiac arrhythmia.

  8. Acute hearing loss.

  9. Septic shock.

  10. Multiple organ dysfunction syndrome (MODS).

I hope this information will help you.

Thanks.
