How Often Does Genital Herpes Come Back?Outbreaks Over Time

A first genital herpes outbreak can be painful and frightening. What most people want to know next is how often it will come back. Long-term studies give a fairly clear picture.

The first year

At a research clinic, 457 people were followed after a first outbreak:¹

• 89% of those with HSV-2 had at least one recurrence.¹
• 38% had 6 or more in the first year, and 20% had more than 10.¹
• People whose first outbreak lasted five weeks or longer had recurrences nearly twice as often.¹

Women tended to have fewer recurrences than men:¹

First-year recurrences	Women	Men
None or one	26%1	8%1
More than 10	14%1	26%1

HSV-1 versus HSV-2

A larger study of 664 people and more than 12,000 recurrences found that in the first year after catching the virus, the median was:²

• 1 outbreak with genital HSV-1²
• 5 outbreaks with HSV-2²

It usually eases with time

• Rates were lower in the second year for both types.²
• A third of people had at least two fewer outbreaks a year by year two.²
• People with HSV-2 followed for more than four years had a median of two fewer outbreaks in year 5 than year 1.²

But it’s not a straight line: a quarter had at least one more outbreak in year 5 than year 1.² The authors suggested doctors check in from time to time on whether daily suppressive treatment is still needed.²

The virus can shed without symptoms

Eighteen women with HSV-2 swabbed daily for 70 days, then again about two and a half years later.³

• The virus was detected on 29% of days at first and 19% later.³
• Shedding without symptoms fell from 24% to 13% of days.³

Even with some reduction, the authors found shedding stayed high two years on,³ so fewer outbreaks don’t mean the virus has gone quiet.

What this means for you

1. Track outbreaks with dates so you and your clinician can see your pattern.
2. Review treatment yearly; see episodic or suppressive treatment.
3. Talk with partners about lowering risk.
4. Know your test results; see herpes blood test limits.

Try: “I’ve had herpes for three years and my outbreaks have dropped to two a year. Do I still need daily medicine, and what should my partner know?”

Down There, Decoded covers repeat symptoms in Chapter 7, “Here We Go Again.” Its Down-There Log records each episode with dates and possible triggers, so a pattern is easy to show a clinician. See the book.
