Symptoms vary depending on the microorganism involved. Bacterial infections like Chlamydia and Gonorrhea may cause abnormal vaginal discharge, pain during intercourse, and burning sensation during urination. Viral infections such as HPV may present with genital warts or abnormal cervical cells detected during a Pap smear. HSV typically causes painful sores or blisters. Yeast infections result in itching, burning, and thick, white vaginal discharge. Trichomoniasis may produce a frothy, greenish-yellow discharge with a foul odor.
