Hand, Foot, and Mouth Disease
- Coxsackievirus A causes Hand, Foot, and Mouth Disease, characterized by:
- Red vesicular rash
- Fever
- Ulcers in the mouth and throat
- The disease is most common in summer and affects children.
Herpangina
- Coxsackievirus A also causes Herpangina, a viral infection of the mouth, characterized by:
- Vesicular ulcerated lesions around the soft palate and uvula
- Fever
- Sore throat
- Pain on swallowing (common cold symptoms)
Pleurodynia (Bornholm's Disease)
- Coxsackievirus B causes Pleurodynia, also known as "Devil's Grip", characterized by:
- Abrupt onset of spasmodic pain in the chest
- Fever
- Malaise
- Headaches
- The disease is known for its extreme unilateral sharp pain in the chest.
Cardiovascular Infections
- Coxsackievirus B can cause myocardial and pericardial infections, leading to:
- Scattered myofiber necrosis
- Migration of WBC's into the heart
- Dilated cardiomyopathy
