Incidence and distribution of herpes simplex virus types 1 and 2 from genital lesions in college women.

During a 9-month period, 9,772 women were treated at the student health center's gynecology clinic. Herpes simplex virus was isolated from 30 of 57 patients clinically diagnosed as suffering from a herpetic or herpetic-like genial infection for a virological incidence rate of 0.31%. Using virus plaque diameter in chick embryo cells and heat stability of viral thymidine kinase, 37% of the isolates were classified as herpes simplex virus type 1 and 63% were classified as herpes simplex virus type 2.
