Adults at risk for infection by sexual exposure. Risk factors associated with sexual transmission among MSM (men who have sex with men) include having multiple sex partners, history of another STD, and anal intercourse. The most common source of HBV infection among adults in the United States is sexual contact. Heterosexual transmission accounts for approximately 39% of new HBV infections among adults,
and transmission among MSM accounts for approximately 24% (CDC, unpublishe data, 2001–2005). Serologic evidence of HBV infection (i.e., anti-HBc positive) has ranged from 10% to 40% among adults seeking treatment in STD clinics (62–64) and from 10% to 25% among MSM aged <30 years (65; CDC, unpublished data, 1999–2000). Follow-up studies identified HBV infection in 20%–42% of susceptible heterosexual
partners of persons with acute hepatitis B (66–68). Among susceptible heterosexual spouses of persons with chronic HBV infection, the seroprevalence of HBV infection
ranged from 25% to 59% (69–71).
