Transmission of Herpes Simplex Virus via Oral Sex

American Family Physician. 2006;73(7):1153.

to the editor: I am trained in, and am an avid supporter of, family medicine. As a lecturer on sexually transmitted infections, I was eager to read the article by Dr. Beauman, “Genital Herpes: A Review,”1 in the October 15, 2005, issue of American Family Physician. The article was thoughtful and the author handled the complexities of genital herpes simplex virus (HSV) infection well.

I was dismayed, however, by the patient education handout entitled, “Genital Herpes: What You Should Know,”1 which followed the article and has a significantly inaccurate statement in the first paragraph. The handout states: “Genital herpes is caused by a different type of the same virus that causes cold sores on the mouth.”1 This statement does not reflect the current incidence of HSV-1 among new cases of genital herpes.24 Historically, HSV-2 was by far the most common cause of genital herpes; however, studies5,6 over the past few years document a rising incidence of HSV-1 in genital lesions, as high as 50 percent in adolescent populations and as high as 78 percent in college populations.

Explaining the transmission of genital herpes and the risks of oral sex to young people, who often do not view oral sex as “sex,” requires that we, as family medicine specialists, be on the forefront of educating our patients about this worrisome trend. This statement in the handout is outdated and a disservice to our patients.

editor’s note: Thank-you to Dr. Groves for pointing out the discrepancy between the article and patient education handout. As Dr. Beauman states, both types of herpes simplex virus (HSV-1 and HSV-2) may cause genital infections that are clinically indistinguishable. We agree that oral-genital contact is an underrecognized but increasingly common mode of transmission of both types of herpes simplex virus. Accordingly, this patient education handout has been updated on our Web site (https://www.aafp.org/afp/2005/1015/p1541.html).
