Does Kaposi sarcoma herpesvirus always lead to Kaposi sarcoma?

Kaposi sarcoma is caused by the Kaposi sarcoma herpesvirus, or herpesvirus 8. However, just because a person has that virus doesn't mean they'll actually develop Kaposi sarcoma. In fact, certain studies claim that anywhere from 5% to 25% of the U.S. population have the Kaposi sarcoma herpesvirus, but only about 6 in every one million people actually develop Kaposi sarcoma each year.
