Monkeypox disease in a breastfeeding infant.

A previously healthy breastfed 7-month-old infant presented with several papulovesicular lesions, a hyperemic pharynx and a petechial enanthema. His mother had confirmed monkeypox infection with similar skin lesions on the chest wall. Skin-to-skin contact is the most likely mode of transmission of monkeypox. Precautions to limit skin contact during activities such as breastfeeding are recommended if suspected skin lesions are present.
