It is an infectious disease caused by herpes simplex virus infection, which can be transmitted indirectly through sexual intercourse and toilet and bath towels contaminated with the virus. Herpes simplex virus invades the body and replicates in the skin cells, causing local inflammation, blisters, pain, ulcers, itching, etc. If the immune system is good, the small vaginal blisters can crust over and heal after a week or so. If the immunity of the body is low or in case of menstruation, the herpes virus can easily cause symptoms such as swollen lymph nodes, elevated body temperature, and weakness. It is advisable to go to the hospital in time for treatment of genital herpes with antiviral drugs such as acyclovir, and local blisters can be treated with acyclovir ointment.
