The basics

What you're actually dealing with

Herpes is a common, lifelong, and very manageable infection caused by the herpes simplex virus. There are two closely related types. HSV-1 is the usual cause of cold sores around the mouth, and HSV-2 is the usual cause of genital herpes, though either type can show up in either place. After the first infection the virus settles into nearby nerve cells and stays there, quiet most of the time and flaring now and then as an outbreak.

It is far more common than most people assume. The majority of adults carry HSV-1, often from a childhood kiss no one remembers, and a large share carry HSV-2 without ever noticing clear symptoms. Plenty of people never get an obvious outbreak. When outbreaks do happen they tend to follow a pattern: a day or so of tingling or itching, then a small cluster of blisters that crust and heal over a week or two. Later outbreaks are usually milder and shorter than the first.

There's no cure, but herpes responds well to treatment. Antiviral pills such as valacyclovir can cut an outbreak short when you feel one starting, and a daily dose can prevent most outbreaks and lower the chance of passing the virus to a partner. This library walks through the whole picture: how to recognize symptoms, how the two types differ, how herpes spreads, how it's tested for, what treatment looks like, and the handful of situations that call for in-person care.

Common questions

Quick answers, before you dig in

The questions people ask most after a first herpes diagnosis or outbreak.

See treatment options
They're two strains of the same virus that tend to favor different places. HSV-1 usually causes cold sores around the mouth, and HSV-2 usually causes genital herpes. The catch is that either type can infect either area, so where an outbreak shows up matters more than which type you carry.
A type-specific test is the only way to know which one you have.
No, but it's very treatable. The virus stays in your nerve cells for life, so no medication clears it completely. Antivirals do a lot, though: they shorten outbreaks, prevent most of them when taken daily, and lower the odds of passing herpes to a partner.
Through skin-to-skin contact, usually with the mouth or genitals. That includes kissing, oral sex, and genital contact. The virus can spread even when there's no visible sore, because it sheds from the skin at times with no symptoms, which is why so many people have no idea when they caught it.
Daily antiviral therapy and condoms both lower the risk to a partner.
For a typical outbreak or for ongoing suppression, usually yes. You complete a short online visit, a licensed Vyta.co clinician reviews it, and if an antiviral is appropriate it's sent to a pharmacy near you, often the same day. A first-ever outbreak, pregnancy, or anything unusual is better seen in person, and a clinician will tell you if that's you.
It varies a lot, and it usually eases with time. Some people get a handful in the first year and then very few; others get them rarely from the start. Genital HSV-2 tends to recur more often than genital HSV-1. For frequent or disruptive outbreaks, daily suppressive therapy can prevent most of them.
