Herpes First Outbreak Versus Recurrence Symptoms

When the vulva stings and swells and small blisters form, many people panic and come knocking at the clinic door. Even with the same herpes, the intensity of symptoms, the speed of progression, and the time to recovery are quite different between a first outbreak and a recurrence. Knowing this difference helps you gauge "whether I am now in a first outbreak or a recurrence" and "whether this is a situation where I should start medication right away." In this article, I have organized the difference in symptoms between a first herpes outbreak and recurrence, the progression pattern, and the treatment by stage and management to reduce recurrence, from the perspective of gynecological care.

Herpes is a disease caused by herpes simplex virus (HSV) infection. It is generally known that type 1 (HSV-1) is associated with around the mouth and type 2 (HSV-2) with the genital area, but in actual practice, cross-infection between the oral and genital areas is not uncommon. The U.S. Centers for Disease Control and Prevention (CDC) explains that genital herpes can arise from both HSV-1 and HSV-2.

The biggest feature of this virus is that once it enters the body, it does not disappear. After the initial infection, the virus lies dormant in the nerve ganglia and reactivates depending on the body's state. In the clinic, reactivation often occurs in situations like the following.

• Accumulated fatigue and lack of sleep
• Mental and physical stress
• Immune and hormonal changes around menstruation
• Other infections such as a cold or fever
• Overwork or a drop in condition

When you are first infected with herpes, the symptoms tend to be most severe. The CDC explains that newly infected genital herpes can show a relatively long course with widespread ulcers. In the clinic too, quite a few patients complain, "The entire vulva is raw and feels like it has holes," and "It stings terribly when I urinate."

The reason a first outbreak is harder is that our body does not yet have immune memory against this virus. As the immune system faces the virus for the first time, the range of blisters and ulcers is wide, the pain is strong, and systemic symptoms such as low-grade fever, muscle pain, and inguinal lymph node swelling may accompany it. It often takes around 2 weeks to recover, and it can be longer if immunity is lowered.

Since a first outbreak has severe symptoms, getting care at the early stage and starting antiviral treatment helps the recovery course. The CDC recommends antiviral treatment for all first-outbreak patients. If the vulvar pain is severe enough to make daily life difficult, you can also refer to an article on vulvar pain of a first herpes infection.

Recurrence generally passes more lightly and quickly than a first outbreak. The CDC explains that recurrent outbreaks tend to be shorter and less severe than the first, with fewer lesions and less prominent systemic symptoms. This is because the body already has immune memory against the virus and responds faster.

Another feature of recurrence is the "prodrome." From about a day before blisters appear, that area may first feel itchy, tingling, or prickling. Noticing this signal is important, because according to the CDC, recurrence treatment is most effective when started within a day of the lesion forming or at the prodrome stage.

Recurrence frequency differs by virus type. The CDC explains that genital HSV-2 infection tends to recur more often than genital HSV-1 infection, and that for HSV-1, recurrence and viral shedding decrease rapidly during the first year of infection. That said, there may be individual variation in the recurrence pattern, so it is good to look at your own pattern together through care.

The table below organizes the general differences between a first outbreak and recurrence that I often explain in the clinic. These are typical patterns at most, and actual symptoms may vary individually depending on immune state and condition.

As the table shows, the principle that "the sooner you start, the better" is the same in both cases. If the symptoms are confusing, it is safer to confirm through care than to judge alone.

The center of herpes treatment is antiviral drugs. There are oral drugs and ointment forms, and the CDC treatment guidelines advise using antivirals such as acyclovir, valacyclovir, and famciclovir for both a first outbreak and recurrence. What is important is the timing of starting, and it is reported that the earlier you start in the early symptom stage, the more it helps the course.

Treatment usually proceeds along the following axes together.

• Antiviral treatment: Using oral and topical drugs according to the timing and symptoms of the outbreak
• Pain relief: Anti-inflammatory analgesics, wound care to protect the affected area, and so on
• Maintaining cleanliness and dryness: Reducing irritation and keeping the affected area dry
• Immune management: Sufficient sleep and nutrition, stress control

For those with frequent recurrences, "suppressive therapy," taking a fixed dose daily, may be considered. The CDC explains that suppressive therapy helps reduce recurrence frequency and lower the viral shedding that occurs when there are no symptoms and the risk of transmission to a partner. That said, which approach fits differs depending on recurrence frequency and lifestyle, so it is good to discuss and decide through care.

One thing to make clear is that, at present, there is no treatment that completely removes the herpes virus from the body. The CDC also states that herpes is not a disease that is cured but a disease that can be managed with medication. So the goal is set not on "eradicating the virus" but on "calming symptoms quickly and reducing recurrence to manage it well." For additional questions about treatment options, you can also get help from an article on whether herpes can be treated by injection.

As important as drug treatment is lifestyle management that reduces the triggers of recurrence. Reactivation of herpes often coincides with the point when immunity is lowered, so keeping your usual condition well is itself recurrence management.

• Reduce fatigue and lack of sleep, and maintain a regular life
• Pay more attention during periods when immunity wavers, such as around menstruation, a cold, and overwork
• Manage stress and keep balanced nutrition

It is good to also remember transmission management. In clinical experience, many people misunderstand that "if there are no symptoms, it is not transmitted," but the CDC explains that the virus can be shed and transmitted to a partner even when there are no symptoms. Therefore, avoid contact until lesions have fully healed, and if recurrences are frequent, I recommend discussing suppressive therapy and transmission prevention together in care. The point that it can be transmitted even without symptoms is explained in more detail in an article on why herpes can be transmitted even without symptoms.

In the following cases, I recommend getting care without putting it off. In particular, when symptoms appear for the first time, it is likely a first outbreak, so early treatment is important for both recovery and subsequent recurrence management.

• When blisters, ulcers, or severe pain appear on the vulva for the first time
• When pain on urination is so severe that daily life is difficult
• When systemic symptoms such as low-grade fever and muscle pain accompany it
• When recurrences repeat often and interfere with life

At our Wooahan Women's Clinic, we conduct antiviral treatment matched to the timing of the outbreak, management to aid symptom relief and recovery, and consultation on lifestyle management to reduce recurrence, together. If similar symptoms repeat, looking at an article for those who cannot sleep because of vulvar itching together may help. We are a 5-minute walk from Exit 4 of Apgujeong Station in Gangnam.
