What is the treatment plan for scrub typhus?

Question

Hello doctor,

Hi doctor, I am a 39-year-old. I recently went hiking, and about a week after I got home, I started having a high fever and severe muscle aches and noticed a small black sore on my leg that looked like an insect bite. I have also developed a rash on my back and chest. I have read about scrub typhus and wonder if it could be the cause. Should I request specific blood tests, like PCR (polymerase chain reaction), to confirm the diagnosis, or is it enough to rely on clinical observation? How soon should treatment with Doxycycline be started to prevent complications? Also, could working with animals at home put me at risk of re-exposure or other infections?

Kindly help.

Hello,

Welcome to icliniq.com.

I understand your concern.

Your symptoms, including the high fever, muscle aches, black sore (eschar), and rash, strongly suggest scrub typhus, especially since you recently went hiking.

Scrub typhus is usually diagnosed based on your symptoms and travel history, and given what you have described, it is very likely that is what you have.

You could consider a PCR or an indirect immunofluorescence assay to confirm the diagnosis with a blood test. Still, it is not strictly necessary since your symptoms and travel history are enough to make the diagnosis.

For treatment, you can start with:

Doxycycline 100 milligrams (take one tablet in the morning and one at night) for seven days.
Paracetamol (1 gram) as needed for fever or pain, up to three times a day.

Make sure to visit a hospital if you develop complications related to scrub typhus or Doxycycline does not seem to work.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
