sexually transmitted disease; venereal disease
An older, somewhat euphemistic term for sexually transmitted diseases, now largely replaced by 性感染症 (seikansenshō) in medical contexts. Still understood but may sound dated.
Venereal disease was once a serious social problem.
He went to the hospital for treatment of a sexually transmitted disease.
General term for venereal disease, less clinical than 性感染症 but more common than 花柳病.
Compound of 花柳 (karyū, 'flowers and willows', a euphemism for the red-light district) and 病 (byō, 'disease'). The term reflects historical associations between sexually transmitted diseases and licensed quarters.
