what is hsv 2

HSV-2, or herpes simplex virus type 2, is a sexually transmitted virus that primarily causes genital herpes. It is mainly transmitted through sexual contact with infected individuals, and the virus can be shed from the skin or mucous membranes even in the absence of visible sores. HSV-2 infection is common and can be asymptomatic or cause outbreaks of blisters or sores. The virus is most contagious when sores are present, but it can also be transmitted when no sores are visible. Condom use and medical male circumcision can provide some protection against HSV-2 infection
