While vaginal infections can sometimes be easily treated with a single dose of antibiotics, some may not go away because they are resistant to treatment, or they may recur because the conditions that predispose to the infection have not changed. Bacterial vaginosis and vulvovaginal candidiasis (fungus) are the most chronic infections. Fighting these infections requires patience and a holistic approach that includes nutrition and lifestyle changes. Viruses that cause warts and herpes in the external genital area go into a dormant phase in the body, even if the lesions heal and disappear, and can reappear when immunity is weakened.
