Genital herpes is a sexually transmitted disease caused by the herpes simplex virus (HSV), mainly HSV-2 and a few HSV-1. It is one of the common sexually transmitted diseases. Genital herpes can recur, causing significant health and psychological impacts on patients; it can also infect newborns through the placenta and birth canal, leading to congenital infection in newborns. Therefore, this disease is also one of the more serious public health problems, and attention should be paid to its effective prevention and treatment.

Epidemiology

1. Source of infection

Humans are the only natural host of the herpes simplex virus. Patients in the acute phase or recovery phase, as well as those infected with the virus without obvious symptoms, are the sources of infection of the disease. It is mainly transmitted through viruses present in blister fluid, local exudate, and the surface of lesioned skin and mucous membranes. The disease is mainly transmitted through sexual intercourse and less commonly through indirect transmission through contaminated objects. In addition, mothers with genital herpes can transmit the virus directly to their newborns through the birth canal during delivery, or if they become ill during pregnancy, the virus can be transmitted to the fetus through the placenta.

2. Transmission routes

Infected people mainly transmit the disease to their sexual partners through sexual contact. Men who have sex with men are also at great risk of infection. Sometimes a person with herpes on or around the lips can infect their partner with genital herpes through oral-genital sex. Therefore, different types of heterosexual or homosexual sexual behaviors can spread genital herpes. Since infectious viruses can survive for several hours in moist environments, indirect transmission via fomites is also possible in rare cases.
