Monkeypox patients around the world are suffering from symptoms not normally linked to the virus, leading to missed and mistaken diagnoses, researchers said.

Doctors are reporting some patients with only single sores from the disease, sometimes in the mouth, anus or genitals, according to a study released Thursday by the New England Journal of Medicine. The cases don’t conform to the US Centers for Disease Control and Prevention’s definition of monkeypox.
