Most individuals infected with HSV-1 or HSV-2 are asymptomatic or have very mild symptoms that go unnoticed or are mistaken for another skin condition. Clinical manifestations of genital herpes differ between the first and recurrent outbreaks of HSV. 15 Because viral shedding is intermittent, failure to detect HSV by culture or PCR does not indicate and absence of HSV infection.
