  1. Abbreviations: HPV=human papillomavirus; MSM=men who have sex with men.
  2. aFor rows measuring the frequency of both HPV types (HPV16 and 18 or HPV6 and 11), when combining specimen types, we included men in the numerator if one type was detected in one specimen (e.g., anal) and the other type detected in another specimen (e.g., external) so that it is possible for the total to be greater than the sum of its parts.
