Rickettsialpox Overview
Learn About Rickettsialpox
Rickettsialpox is a disease spread by a mite. It causes a chickenpox-like rash on the body.
Rickettsia akari
Rickettsialpox is caused by the bacteria, Rickettsia akari. It is commonly found in the United States in New York City and other cities. It also has been seen in Europe, South Africa, Korea, and Russia.
The bacteria are spread by the bite of a mite that lives on mice.
The disease begins at the site of the mite bite as a painless, firm, red lump (nodule). The nodule develops into a fluid-filled blister that bursts and crusts over. This lump may be up to 1 inch (in) or 2.5 centimeters (cm) wide. These lumps usually appear on the face, trunk, arms, and legs. They do not appear on the palms of hands and soles of feet. Symptoms usually develop 6 to 15 days after coming in contact with the bacteria.
Other symptoms may include:
- Eye discomfort in bright light (photophobia)
- Fever and chills
- Headache
- Muscle pain
- Rash that looks like chickenpox
- Sweating
- Runny nose
- Sore throat
- Cough
- Enlarged lymph nodes
- Loss of appetite
- Nausea or vomiting
The rash is not painful and usually clears within a week.
The goal of treatment is to cure the infection by taking antibiotics. Doxycycline is the medicine of choice. Treatment with antibiotics shortens the duration of symptoms usually to 24 to 48 hours.
Without treatment, the disease usually resolves within 7 to 10 days.
