APRs antenatal women army conscripts less than 0.15%. increased significantly 1994 1998 patients (p < .001), FSWs TB .05) original provinces. also younger age groups IDUs FSWs. CONCLUSION Vietnam's increasing predominantly most rapidly IDUs. However, are rising still low Vietnam, at present, early phase has time take effective appropriate actions.
