Task: Answer Verification
Input (English): Question: Are epstein-Barr virus and human herpes virus-8 associated with juvenile nasopharyngeal angiofibroma?
Answer: Angiofibroma does not appear to be associated with either HHV-8 or EBV, thereby excluding these viruses as potential etiologic agents. The lack of a correlation between the proliferative index and the age of the patient suggests the proposed puberty induced, testosterone-dependent tumor growth may not play a significant role in tumor development.
Output (English): no
