Genital herpes is a sexually transmitted disease caused by HSV virus infection. Nearly 60% of patients have a recurrence within one year after the first herpes II virus infection, and the recurrence can be 4-6 times in the first year. The number of recurrences decreases later. There is no specific prevention method for genital herpes, and animal experiments have shown that vaccination with dead HSV vaccine or live attenuated vaccine are immune, so the virus is closely related to certain cancers, so it is not used for routine prevention. Herpes II virus can be latent at the spinal ganglion, and there is no specific drug for the virus. Therefore, when the body’s resistance decreases, the virus replicates and multiplies at the ganglion and then re-emerges along the nerve bundle to the original lesion. The following measures can be taken to prevent genital herpes: 1. forbid intercourse during treatment, and if necessary, the spouse should also be examined. 2, avoid unclean sexual intercourse and improper sexual relations, active genital herpes patients are prohibited to have sexual relations with anyone. 3, after cure or have a recurrence, pay attention to the prevention of cold, cold, strain and other triggering factors to reduce recurrence. 4.Penis condoms may reduce the spread of the disease, especially during the asymptomatic detoxification period, but when genital damage occurs, the use of penis condoms cannot avoid transmission. 5.For the care of local damage, attention should be paid to keep it clean and dry to prevent secondary infection.
