Abstract
This article reviews Japanese HIV/AIDS surveillance data from 1985 to 2011. It revealed that heterosexual males are more prone to be detected as “AIDS case”, while male homosexuals and females are detected more as “HIV case” irrespectively of sex, age, infection route, residential area and nationality; and probability of detection as “AIDS case” increased with advance of age irrespective of sex and infection route. Interpretation of the data requires further information on clinical latency of AIDS that could be different depending on the infection routes, different sex, and different ages; nature of the acute phase syndrome; and factors that enhance it, such as, route and dose of infection; and mucosal immunity involved in sexually transmitted HIV/AIDS infection and influence of aging and sex on it.
