Clinical Features
Monkeypox is a rare disease that is caused by infection with monkeypox virus. Monkeypox does not occur naturally in the United States. However, cases have occurred associated with international travel or importation of animals from areas where the disease is more common. The incubation period for monkeypox generally falls within 7-14 days, but can range from 5-21 days. Illness begins with fever, headache, muscle aches, backache, swollen lymph nodes (submandibular, cervical, axillary, or inguinal), chills, and exhaustion. Within 1-3 days following onset of fever, the patient typically develops a rash, often descending from the face to other parts of the body. Lesions progress through macular, papular, vesicular, and pustular stages before falling off. Illness typically lasts 2-4 weeks. Beyond supportive care, there is no proven, safe treatment for monkeypox virus.

Transmission occurs via contact with an animal, human, or materials contaminated with the monkeypox virus, entering the body through broken skin, respiratory tract, or mucous membranes. Human-to-human transmission is thought to occur primarily through large respiratory droplets. As these droplets generally cannot travel more than a few feet, prolonged face-to-face contact is required for transmission. Other means of human-to-human transmission include direct contact with body fluids or lesion material, as well as indirect contact with lesion material (i.e. contaminated clothing or linens). Animal-to-human transmission may occur via bite or scratch, preparation of bush meat, direct contact with contaminated body fluids or lesion material, or indirect contact with lesion material (i.e. contaminated clothing or linens).
