In Japan, HIV infection is classified as “HIV” or “AIDS” depending upon whether the infection was detected before or after development of AIDS. For male homosexuals, in the plot of the number of “AIDS” versus the number of “HIV”, the plots fell on a straight line with a slope close to 1. When the number of “HIV” stopped increasing, that of “AIDS” stopped increasing. The number of “HIV” in one region or in one age group was correlated with that of other regions or that of other age groups, respectively. No such correlation was detected for male heterosexuals.
Male homosexuals and females were detected more as “HIV” than male heterosexuals. Detection as “AIDS” increased with age in all the infection categories. Our analysis supported by others suggested that the higher rate of detection as “HIV” among male homosexuals and females than among male heterosexuals was attributable to higher risk of the receptive sexual intercourse, and the higher incidence of “AIDS” among elderlies to immunological senescence.
