The condition is caused by bacteria. The bacteria occur in mites. Mites are small, spidery insects. Mites infect mice. You can get infected by being bitten by a mite.

First of all a papule appears on the skin. The papule turns into a wound covered by a dark scab. When the wound heals, it leaves a scar behind. You can then get a fever. You may also get headaches and be more sensitive to bright light. The lymph nodes may swell up. The lymph nodes are small bean-shaped objects. They are found throughout the body. Lymph nodes filter the tissue fluid. They are part of the defense system. Reddish papules and small blisters may form all over your body on your skin. These skin changes do not affect the flats of your hands or the soles of your feet.
