No, in fact, the most common vaginal infection is bacterial vaginosis (BV), which is an infection caused by an imbalance of bacteria in the vagina. Bacterial vaginosis is distinguished by a fishy odor and a thin, grayish-white discharge and a drop in vaginal acidity. BV is caused by an abnormal growth of bacteria and must be treated with prescription antibiotics. By contrast, yeast infections do not usually cause an odor, and the discharge will often be thick, white, and lumpy with associated vaginal itching and irritation. If left untreated, BV may lead to a serious infection of the reproductive organs called pelvic inflammatory disease and complications in pregnant women, including premature birth.
You should see your doctor if your experiencing symptoms like a fishy odor, change in discharge, or sudden irritation within 48 hours after a new sex partner to make sure you do not have a sexually transmitted disease or BV.
Another common vaginal infection is Trichomoniasis (Trich), which is a parasitic infection. Symptoms of Trichomoniasis may include the following: itching, burning, redness or soreness of the genitals, discomfort with urination, or a thin discharge with an unusual smell. The discharge can be clear, white, yellowish, or greenish. Like BV, Trichomoniasis must be treated by a healthcare provider.
There are also non-infectious causes of vaginal inflammation and irritation. These are usually caused by an allergic reaction or irritation from vaginal sprays, douches, spermicidal products, soaps, detergents, or fabric softeners. Burning, itching, or vaginal discharge may be present even if there is no infection.
