Herpes, explained

What herpes is

Herpes is a common skin virus. Its proper name is the herpes simplex virus, usually shortened to HSV. Once you have it, it stays in the body for the long term, quiet most of the time and occasionally causing an outbreak — a patch of small blisters or sores on the skin.

There is no medicine that removes the virus from the body, and for most people there does not need to be. It is manageable, and it is usually minor. Naming it plainly matters here: a lot of what makes herpes feel hard is what people believe about it, not what the virus actually does.

It sits in the same family as the viruses behind cold sores and chickenpox — extremely common, mostly ordinary, and something a large share of adults carry without ever thinking much about it.

HSV-1 and HSV-2

There are two closely related types.

• HSV-1 is the type most people first meet as cold sores around the mouth.
• HSV-2 is the type more often associated with genital herpes.

The old, tidy split — HSV-1 above the waist, HSV-2 below — no longer holds. Either type can appear in either place. What the type is called matters far less than how it actually behaves for you: how often outbreaks come, and how much they bother you. Both types are managed in much the same way.

How it shows up

Herpes does not show up the same way for everyone. Many people have very mild symptoms, or none they ever notice. When it does show up, there are two patterns worth knowing.

The first outbreak

A first, or primary, outbreak is usually the most noticeable one. It can involve tender blisters or sores, and some people also feel generally unwell — a bit like fighting off a cold — for a few days. It can be uncomfortable, and it can be a shock. It also tends to be the worst it gets. If this is where you are right now, start with just diagnosed — it is written for exactly this moment.

Recurrences

After the first one, later outbreaks are called recurrences. They are usually shorter and milder than the first, and for most people they become less frequent over time. Many people learn to recognise a prodrome — the tingling, itching or warning signs that can arrive a day or two before an outbreak. Noticing the prodrome early is useful, because it is the point at which a plan does the most good. There is more on all of this in outbreaks and triggers.

How common it is

This is the part most people are never told. Herpes is one of the most common infections there is. The World Health Organization estimates that 3.8 billion people under 50 — about two in three — carry HSV-1, the type behind most cold sores, and that 520 million people aged 15 to 49, around one in eight, carry HSV-2, the type more often linked to genital herpes (WHO, 2020 estimates).

The exact numbers vary by source and by country, and they are best read as broad estimates rather than precise facts. But the direction is not in doubt: this is ordinary, and it is everywhere. If you have just been diagnosed, you are in very large company, whether or not the people around you have ever said so.

When there are no symptoms

Herpes can be present on the skin from time to time without any outbreak and nothing to see or feel. This is sometimes called asymptomatic shedding. It is normal, and it is part of why the virus is so common: it can be passed on even when there is nothing visible.

That is worth understanding plainly rather than fearing. Steps like daily suppression, condoms, and avoiding contact during an outbreak can lower the risk of passing it on — they do not remove that risk, and no honest source will tell you they do. We cover what the evidence actually says, with the numbers you can share, in suppression and transmission.

Living with it, and managing it

Herpes is manageable, and most people settle into managing it without much fuss. Because the virus can't be removed from the body, the goal is simpler: fewer outbreaks, milder ones, and a way to deal with one quickly when it starts.

Broadly, there are two approaches, and many people use both at different times:

• Episodic — a rescue pack. A short course kept at home, ready to use the moment a prodrome or outbreak starts. It helps an outbreak settle sooner.
• Daily suppression. A daily plan that aims to reduce how often outbreaks happen, and to lower the risk of passing herpes on — though it doesn't remove that risk. It is usually considered when outbreaks are frequent or bothersome, or when reducing transmission risk matters to you.

Neither approach removes the virus. What a plan can do is make outbreaks less frequent and help them settle faster — that is management, and no honest source will promise you more. Which approach fits is a conversation with a clinician, and it can change over time. You can see how the plans are shaped on plans.

Where the stigma came from

If herpes is this common and this manageable, why does it carry so much shame? The answer is more recent, and more manufactured, than most people realise.

According to the account set out by the Herpes Viruses Association, genital herpes was largely unremarkable in public attitudes until the 1980s, when pharmaceutical marketing and press coverage turned a common virus into a symbol of shame (this is the account given by the Herpes Viruses Association and widely repeated; we have not independently verified the history). In other words, the stigma is younger than the treatment for it. It was built — which means it can come apart.

That is the whole idea behind Interval: a common virus, met with ordinary competence. Calm is not us minimising anything. It is us being accurate.
