There are many reasons for the occurrence of vulvitis, mainly including recent sexual intercourse, the use of unclean sanitary pads, wearing tight, non-breathable pants, as well as not paying attention to vulvar hygiene, not cleaning the vulva for a long time, etc. It could also be due to direct contact transmission, such as through sexual activity, or contact with contaminated towels, underwear, swimwear, as well as sharing wash basins, bathtubs, toilet seats, or swimming in public pools, among others.
