Depending on the stage of the disease, physical findings may include low-grade fever, enlarged lymph nodes (submental, submandibular, cervical, inguinal), and skin rash with typical progression: Macular (1-2 days), papular (1-2 days), vesicular (1-2 days), pustular (5-7 days), scabs (7-14 days)^{_Monkeypox_|_Poxvirus_|_CDC-1|[1]}.

• Low-grade fever (temperature, 100.8°F, 38.2°C)^[2]
  • Fever before rash ​is a key characteristics to identifying monkeypox^{_Monkeypox_|_Poxvirus_|_CDC-1|[1]}

Skin lesions develop after the prodrome (early set of symptoms). The United States Centers for Disease Control and Prevention described following characteristics of lesions to identify monkeypox^{_Monkeypox_|_Poxvirus_|_CDC-1|[1]}:

• Relatively the same size and same stage of development on a single site of the body
• Well-circumscribed, deep seated, and often develop umbilication (resembles a dot on the top of the lesion)
• Disseminated rash is centrifugal (more lesions on extremities, face) ​
• Includes palms and soles​
• often painful until the healing phase when they become itchy (crusts)

The skin lesions usually develop simultaneously as macular (1-2 days), then evolve to papular (1-2 days), vesicular (1-2 days), pustular (5-7 days), and finally scabs (7-14 days).

• Lymphadenopathy (submental, submandibular, cervical)

• Inguinal lymphadenopathy
  • Lymph nodes may increase in size in seldom cases after sexual intercourse^[3]
• Signs of proctitis, or inflammation of the rectum^[4][5]
  • Anal and rectal pain
  • Rectal bleeding
  • Malodorous, mucopurulent discharge
