Genital herpes (HSV-1 and HSV-2)

The Greeks named it. Herpes comes from herpein, to creep, describing how the sores spread across the skin. Roman writers record that the emperor Tiberius tried to ban kissing at public ceremonies to stop an outbreak of facial sores doing the rounds, which if true makes him the author of the world's first public health measure against cold sores. Shakespeare has Mercutio describe ladies' lips blistered by plagues. Herpes is not new, and it is not rare. It is one of the most common viral infections on earth.

Getting the fear the right size

Here is the honest calibration Seth would want stated plainly. For the overwhelming majority of people, genital herpes is a manageable skin condition: occasional outbreaks of small sores, usually milder and less frequent over the years, and long stretches of nothing in between. Most people who carry the virus have few or no symptoms and never know. It does not damage fertility, it does not shorten life, and it says nothing about anyone who has it, which by adulthood is a very large share of the population. The 1980s made it a monster; one Time magazine cover branded it the new scarlet letter, before HIV arrived and put the panic into brutal perspective. Most of the dread attached to herpes is a cultural hangover, not a medical fact.

Where the seriousness is real and specific is at the very start and the very end of life. A first outbreak caught in late pregnancy is the genuine danger: neonatal herpes, where the virus passes to a newborn, is uncommon but devastating, carrying a real risk of death and lasting disability, which is why a new outbreak near delivery is managed carefully and can change how a baby is delivered. In people with severely weakened immune systems it can also be serious. Those situations deserve real vigilance. A cold sore on an otherwise healthy adult does not.

How it is handled

Herpes is diagnosed differently from the other infections here. A swab of an active sore is the reliable test, so it is best assessed when something is actually there to see. Blood tests for herpes antibodies exist but are not part of a routine symptom-free screen, and a doctor will explain when they help and when they only cause confusion. There is no cure, but antiviral tablets treat outbreaks well, shorten them, and taken regularly can prevent them, which for the small number of people with frequent recurrences is genuinely life-improving.

The honest summary

Herpes is common, usually mild, and unfairly feared, with two real exceptions that matter enormously: a new infection late in pregnancy, and people whose immunity is compromised. Get the fear the right size, know the exceptions, and it becomes what it usually is: ordinary.
