Whether vulvovaginal itching in women is contagious or not depends on the cause of the vulvovaginal itching. In the case of trichomonas vaginitis, the infection can be transmitted through direct contact during sexual intercourse. And if there is vaginal inflammation caused by mycoplasma infection, it can be transmitted through sexual intercourse. However, if the vaginal itching is caused by bacterial infection, mold infection, or dysbiosis, there is usually no obvious contagiousness. Therefore, for women with obvious vaginal itching, it is necessary to determine whether there is vaginal inflammation through routine examination of the leukorrhea, which can be treated with topical medication. And in the case of severe vaginal itching try to avoid sexual intercourse for a short period of time, can effectively improve the symptoms, and can effectively prevent contagion.
