Living with Rickettsialpox

A rare infection spread by mites that causes a skin sore, fever, and a blister-like rash, and clears on its own.

Understanding Rickettsialpox

Rickettsialpox is a rare infection caused by Rickettsia akari bacteria that are spread by mites.

It starts with a small, painless blister-like bump that usually turns into a sore with a dark scab (eschar). A rash with small bumps and blisters then spreads over the body. People may also have swollen lymph nodes, fever, tiredness, and headaches. GARD says whole-body symptoms go away within 6 to 10 days. It can occur at any age.

GARD lists these symptoms in its summary:
