A disseminated infection, for example, has extended beyond its origin or nidus and involved the bloodstream to "seed" other areas of the body.

This infection can involve the entire sole of the foot and extend onto the sides of the foot.

The infections involve mucous membranes, skin, and the respiratory tract.

The infection may be potentially serious or life-threatening and involve the entire body (systemic).

The infection usually involves the small intestine, but over time, the disease may affect various parts of the body, including the heart, lungs, brain, and eyes.

The infection occasionally involves the prostate gland, seminal vesicles, or epididymes and testes.

The infection usually involves the herpes simplex virus type 2, which is sexually transmitted.

The infections involve the Fusarium fungus, which is frequently found in drains and sinks, particularly in tropical regions.

External incision and drainage is performed if infection involves the perimandibular spaces.
