Women with herpes simplex virus (HSV) infection are usually easily identified by the presence of vesicular eruptions in the perivaginal area.
Women tend to seek prompt medical attention due to the high probability of symptomatology attributed to STIs.
Cervical cancer may be considered an AIDS-defining illness.
Urologists can easily differentiate women with urinary tract infections from those with vaginal infections by taking a thorough history of their lower urinary tract symptoms.
Chancroid affects more women than it does men.
