Herpes Spreads, Even Without Symptoms
April 18, 2011 - You don't have to be in the middle of an outbreak to pass virus to sex partner
Most people with genital herpes, a sexually-transmitted viral infection, don't know they have it. And many who know they're infected mistakenly believe they can only pass the virus to their sex partners if they have genital lesions. A new study finds transmission of the virus is much easier than that, and suggests that sexually active people should get tested for genital herpes. The disease not only has serious consequences for pregnant women, but can also make people more vulnerable to HIV, the virus that causes AIDS.
Education
Ninety percent of American teenagers take classes on sexually-transmitted diseases by the time they graduate from high school. Yet despite that, the U.S. Centers for Disease Control reports that teens between the ages of 15 and 19 have higher rates of sexually-transmitted disease than any other age group. Genital herpes is a disease that frequently goes undiagnosed. Most infected people are unaware they have the disease.
Doctors Anna Wald and Christine Johnston, from the University of Washington in Seattle, studied 500 people. Some had genital herpes. Others had never had a herpes outbreak, but they had antibodies for genital herpes, which is also called herpes simplex virus two, or HSV-2. "This was the first study to look over time at people that have HSV-2 infection but dont have a history of genital herpes," says Wald, "and we really did not know before this how often the virus is active in the genital tract of such persons."
The researchers examined swabs the volunteers took of their genital area daily for 30 days. The goal was to find out how often the virus was active. "Many people think with genital herpes infections that they can only spread the virus when they have symptoms," says Johnson. What the researchers found out was quite different. For those who had antibodies for genital herpes, but did not have a history of the disease, the virus turned out to be active about 10 percent of the time. "Even people without a clinical history of genital HSV-2 are capable of spreading the virus to sexual partners," Johnson says.
