Herpes Simplex Virus Type 1 (HSV-1) infections are acquired through direct person to person contact, most typically by a nongenital route. Recurrent infections are clinically apparent as fever blisters or cold sores. HSV 2 infections are usually acquired through sexual contact. 85% of genital herpes is caused by Type 2 virus and 15% caused by Type 1 virus. This assay helps in determining recent exposure to HSV Types 1 & 2.
