Coxsackie A Variant Virus, also known as CA16, is a strain of the Enterovirus family that primarily affects infants and young children. CA16 is responsible for causing Hand, Foot, and Mouth Disease, a common viral infection characterized by fever, sores in the mouth, and a rash on the hands and feet. While "Coxsackie A Variant Virus" is the scientific term used to describe this specific strain, it is also commonly referred to as simply "CA16" in medical literature and research. These synonyms help streamline communication among healthcare professionals, enabling efficient discussions and quick identification of the virus and its associated symptoms.
