A daily swab of the genital area was self-collected for HSV-2 detection by polymerase chain reaction, in order to compare the effect of valaciclovir 1 g once daily for 60 days versus placebo on asymptomatic viral shedding in immunocompetent, HSV-2 seropositive subjects without a history of symptomatic genital herpes infection. Determination of Interactions between Tegument Proteins of Herpes Simplex Virus Type 1. 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.

Distinguishing between infection caused by HSV types 1 and 2, especially in patients with subclinical or unrecognized HSV infection. Infections with HSV types 1 and 2 can differ significantly in their clinical manifestations and severity.

The genomes of human herpes virus type-1 and type-2 share a high degree of sequence identity; yet, they exhibit important differences in pathology in their natural human host as well as in animal host and cell cultures. (UL4, UL29, UL30, and UL31) differs in infections between the two virus types. Detect and differentiate between type 1 and type 2 herpes simplex virus (HSV).
