Recent decline in gonorrhea incidence in Israel: possible association with the AIDS pandemic

The effect of the AIDS pandemic on the sexual behavior of the general population has not been clearly established. Since trends in the incidence of other sexually transmitted diseases may be a good marker of such behavioral changes, gonorrhea incidence in the civilian and military populations in Israel was examined during the period 1963-87. In the civilian population, the rates were relatively stable until 1967, when they increased to a peak in 1970 and then declined to the earlier levels. In 1982 a further decline began, which accelerated considerably in 1986 when the rates declined by 38%. During 1987 the decline was even more dramatic, with a drop of 60% compared with the rate of the previous year. A similar trend has been noted in the military population. The recent sharp decline in gonorrhea incidence may be related, at least partly, to a change in sexual behavior associated with the fear of AIDS. If so, its magnitude suggests that such changes have not been restricted to high-risk groups.
