Herpes No Boyfriend How

“My boyfriend has no symptoms at all, so why did only I get herpes?” It’s one of the most frequently heard questions in the clinic. People who come in startled by a stinging vulva, a sore feeling when urinating, and small blisters almost without exception raise this question. To get straight to the point, the fact that the other person has no symptoms does not mean they are not the source of infection. This is because herpes is a virus that can be transmitted even without visible blisters. In this article, I’ll organize that principle along with the reasons you don’t need to worry too much.

Genital herpes is caused by herpes simplex virus (HSV) types 1 and 2. Type 1 has been known to be common around the lips and type 2 to mainly be involved in the genital area, but recently cases of type 1 causing genital infection are also increasing, so the boundary is not as clear as before. When damaged skin or mucosa is exposed to the virus, infection occurs, and in women, blisters or ulcers are observed around the vulva and the vaginal opening.

Symptoms appear differently from person to person. In the clinic, at the first outbreak, multiple blisters and ulcers often appear at once with severe pain, accompanied by stinging when urinating or flu-like symptoms such as low fever·muscle aches. Conversely, at recurrence, it may pass locally on one side and relatively mildly. If you’re curious about the difference between a first herpes infection and recurrence, it helps to also read an article organizing the difference in symptoms between a first herpes outbreak and recurrence.

The key is asymptomatic viral shedding. Herpes can release the virus to the skin surface even in a state with no blisters or ulcers at all and no pain. This is called asymptomatic viral shedding, and the U.S. Centers for Disease Control and Prevention (CDC) explains that a considerable portion of genital herpes is transmitted precisely during this symptom-free period. It’s a concept similar to the asymptomatic infection we became familiar with through the coronavirus pandemic.

In fact, looking at studies that tracked people infected with HSV-2, the virus was reported to be detected on a certain proportion of days even in people who had never had symptoms. In other words, the other person can transmit the virus while looking perfectly fine, without knowing they themselves are infected. CDC statistics also summarize that most genital herpes infections occur through people who do not know they are infected or who had no symptoms at the time of transmission. So the situation of “my boyfriend is fine but only I got it” is something that is fully explainable medically. The point that herpes can be transmitted even without symptoms is covered in more detail in the story of herpes being transmitted even without symptoms.

Infectivity varies depending on how much virus comes out and at what period. Generally, the possibility of virus detection is highest during the active period when blisters are present, and once scabbing begins, that possibility decreases. However, “decreases” does not mean “none,” and viral shedding is reported even during the scabbed period or periods with no symptoms at all. Also, the period when prodromal symptoms such as stinging or itching are felt tends to have high infectivity, so caution is needed.

Organized by period, it is as follows.

The CDC recommends avoiding sexual contact with an uninfected partner while blisters or prodromal symptoms are present, and being counseled together on the point that there is a transmission risk from viral shedding even when there are no symptoms. If symptoms are suspected, don’t judge alone; please feel free to inquire through do you have suspected symptoms now and need a consultation.

Many people feel discouraged, thinking “Am I the only one like this?” but herpes is a far more common infection than you might think. The World Health Organization (WHO), in a 2024 release, estimated that as of 2020, more than 500 million people among the world’s population aged 15–49 are infected with HSV-2, and stated that more than one in five adults has genital herpes. In the same estimate, women showed a higher infection rate than men, which is explained by the fact that transmission from men to women occurs more readily in sexual contact.

In my clinical experience, this point that it is “more common in women” is something that fosters misunderstanding in the clinic. While the male partner has no symptoms and is not tested, so he doesn’t know he is a carrier, women often have symptoms appear clearly on the vulva and are discovered first. So it’s easy to get the impression that “only I got it,” but if you remember that it is in fact a very common virus, your mind becomes much lighter. Herpes information that women around the world would do well to know is organized further in global herpes infection facts for women.

Unfortunately, to date there is no treatment medication or preventive vaccine that completely eliminates herpes. The herpes simplex virus, once it enters the body, has the characteristic of lying dormant in the nerve ganglia and reactivating when immunity drops, so it is difficult to eradicate the virus itself. So the goal of treatment is set not on “eliminating” but on “managing well.”

Even within the same virus family, human papillomavirus (HPV) has preventive vaccines such as Gardasil·Cervarix that are of great help in preventing cervical cancer, so if you are in the relevant age group, I recommend making sure to get vaccinated. However, the point that HPV also has no treatment medication that eliminates an already-established virus is the same as herpes. You can find detailed information on the HPV vaccine and testing in HPV testing and management important for women, and for whether you can get the vaccine even after already being infected, refer to the whether you can get the HPV vaccine after HPV infection Q&A.

The core of treatment is antiviral medication. Antiviral medication does not completely eliminate the virus, but it is used to reduce the duration that symptoms last, lower the frequency of recurrence, and reduce the risk of transmission. There are broadly two approaches.

• Episodic treatment, taken briefly when symptoms begin: taking it right away at the early stage of prodromal stinging symptoms or when blisters form, to quickly calm the symptoms.
• Suppressive treatment, taken daily for a set period: for cases where recurrence is frequent or symptoms are severe enough to greatly disrupt daily life, taking it daily to reduce recurrence.

According to the CDC and the 2024 European guidelines, suppressive treatment is reported to considerably lower the frequency of recurrence in patients with frequent recurrence, and is summarized as also helping to reduce the risk of transmission to the partner in couples with different infection statuses. There can be individual differences in effect and the appropriate approach, so it is best to decide together with the medical staff after looking at the recurrence pattern and lifestyle pattern. If you’re curious about whether injection treatment is possible, the Q&A on herpes injection treatment is also a helpful reference.

The point I always emphasize in the clinic is to visit quickly without delay if symptoms are suspected. This is because the earlier treatment is started, the faster symptoms improve, the more infectivity is reduced, and the fewer cases of worsening there are.

The most important variable is the individual’s immune status. In cases of good immunity, many people never recur for life after being infected once, or even if they recur, it passes so mildly that they themselves are unaware. Conversely, when immunity drops due to overwork·stress·lack of sleep·other conditions, there is a tendency for recurrence to become frequent. So taking care of the basics such as sufficient sleep, a balanced diet, and stress management becomes part of herpes management itself.

Just because you’ve been diagnosed with herpes, there’s no need to blame yourself excessively or be afraid. As seen above, it is a very common infection, and if managed well, you can live without great disruption to daily life. However, in the following cases, I recommend receiving care without delay.

• When blisters·ulcers newly appear on the vulva or pain·urination pain is severe
• When frequent recurrence becomes a burden on daily life or relationships
• When you are planning a pregnancy or are pregnant (there is a risk of transmission to the newborn, so separate consultation is needed)
• When other sexually transmitted infections are also suspected

If similar symptoms recur or you’re worried about other sexually transmitted infections, looking together at an article organizing what the 12-type sexually transmitted infection test is helps with test selection. If you have symptoms but hesitate over what to do, please feel free to inquire through tell us your symptoms and get a prompt care consultation. I hope you all have a healthy year.
