the high incidence of eb virus infections ( and possibly of other viruses ) in patients with african lymphoma and , to a lesser extent , in patients with lymphosarcoma in the temperate zones , is thought to be due to its being a passenger virus which persists in the human body and , since it is lymphotropic , presents an opportunistic infection of proliferating lymphoid cells .
