Coxsackie group A commonly cause ?
Coxsackie A viruses are part of the Enterovirus genus. They are divided into groups A and B. Group A is associated with herpangina, hand, foot, and mouth disease (HFMD), and sometimes herpetic gingivostomatitis. Coxsackie B is more linked to viral myocarditis, pericarditis, and pleurodynia (Bornholm disease). So the question is asking what Coxsackie A commonly causes. The options are missing, but the correct answer must be one of the diseases caused by Coxsackie A.
Assuming the options include herpangina, HFMD, and maybe others like meningitis (which can be caused by both groups), I need to structure the explanation. The core concept is the clinical manifestations of Coxsackie A. The correct answer would be herpangina or HFMD. Let's say the correct answer is herpangina.
Now, I need to explain why herpangina is correct. Herpangina is characterized by fever, sore throat, and vesicles in the posterior pharynx. Coxsackie A16 is a common cause. Then, for the wrong options, if another option is myocarditis, that's Coxsackie B. If another is HFMD, that's also Coxsackie A, but maybe the question is different. Wait, the user's correct answer is missing. Let me check the original question again. The user wrote "Coxsackie group A commonly cause ?" with options A-D and correct answer blank. The correct answer is likely herpangina or HFMD. Let's assume the correct answer is herpangina.
So, in the explanation, the core concept is the difference between Coxsackie A and B. The correct answer is herpangina. The wrong options could include myocarditis (B), meningitis (possible for both but more B), HFMD (also A but maybe another option). The clinical pearl would be to differentiate between A and B. Let me structure the explanation accordingly. Need to make sure each part is concise and fits within the character limit. Also, check for precise terminology and exam-relevant points.
**Core Concept**
Coxsackieviruses are single-stranded RNA enteroviruses divided into groups A and B. Coxsackie A viruses predominantly cause vesicular oral and skin lesions, while Coxsackie B viruses are linked to systemic infections like myocarditis and pleurodynia.
**Why the Correct Answer is Right**
Coxsackie group A is the primary causative agent of **herpangina**, characterized by fever, sore throat, and painful vesicles on the posterior pharynx. This is due to direct viral cytopathic effects on the oropharyngeal mucosa. Coxsackie A16 is the most common serotype associated with this condition.
**Why Each Wrong Option is Incorrect**
**Option A:**
