How common is ABV in the USA?     In the United States, over half of adults have been infected with ABV by age 40. Once ABV is in a person's body, it stays there for life and can reactivate.  Match terms with descriptions based on the text above. You can use an answer more than once or not at all.                                                             "Over half of adults have been infected with ABV by age 40."                                                             ABV could belong to this group of viruses: A. Human Papilloma Viruses B. Incidence of ABV C. Herpesviruses D. Prevalence of ABV by age 40
