A Prospective Study of Sexual Transmission of Human T Lymphotropic Virus (HTLV)–I and HTLV‐II

Abstract

The incidence of sexual transmission of HTLV-II may be similar to that of HTLV-I, and female-to-male transmission may play a more important role than previously thought. HTLV-I and -II proviral load may be lower in sexually acquired infection, because of a small infectious dose.
