I’m sure my boyfriend doesn’t have herpes, a patient recently told Dr. Shrier, a researcher on sexually transmitted infections, goes through this kind of conversation all the time.Lydia Shrier, an adolescent medicine specialist at Children’s Hospital Boston. Patients tell her that they’ve never had blisters or lesions or sores, and so cannot possibly have genital herpes. It falls to her to disabuse them of these notions, saying: “You can have lesions or not, you can have symptoms or not, you should basically be operating the same way, which is to assume that everyone has herpes.” That means taking precautions, from limiting sexual contact to using condoms. I read the article about five times myself, saying, wow, and I do this for a living.This blocks viral replication and later gene expression by the virus.Now Knipe and his colleagues have shown that compounds that block this crucial step in HIV infection also prevent genital herpes and other herpes virus infections from taking hold.The new study, by quantifying how much virus is shed even in the absence of symptoms, “is a real ‘aha! FLATOW: You’re saying that between 50 and 75 percent of them have herpes type 2? More reasons that herpes has spread so far and wide: It does not need intercourse to spread; mere skin-to-skin contact is enough.

Wald said, “Asymptomatic shedding may be the central phenomenon of transmission.” In the old days, doctors would warn herpes patients to avoid sexual contact mainly when they had active lesions, believing that was the only time they were really contagious. -In the general population, one-fifth of women and 11.5% of men are infected. If someone with HSV-1 performs oral sex, the receiving partner may contract genital herpes, though it is HSV-1 rather than the typical 2.But evidence has long been growing that herpes can be transmitted even when no lesions are visible. And HSV-1 is so widespread that pretty much everyone gets it by the time they’re elderly, she said.Meanwhile, Knipe and his colleagues are continuing to fight these viruses on another front.
