New Information on Herpes

Source: Curr Opin Infect Dis. 2014;27(1):75-83.

OK so we all know Herpes is bad news. How bad news? This bad news:

  1. It cannot be cured. Once you have it, you have it for life.
  2. It is highly contagious and spread by skin-to-skin or skin-to-mucosa contact EVEN WHEN a person does not have any symptoms. This is called asymptomatic viral shedding. More on that later.
  3. It increases the risk of contracting HIV 2 to 3 times.
  4. It can infect a baby during delivery and cause the baby to become very sick.
  5. It can cause very painful blisters and ulcers.

Some new information was recently made available on Herpes and I would like to share it with you.

  • Herpes Type 1 infects the mouth and Herpes Type 2 infects the genitals right? WRONG!

HSV 1 (Herpes Simplex Virus Type 1) is found to be twice as commonly found in the genitals compared to HSV 2 (Herpes Simplex Virus Type 2). So if you test positive for HSV 1, it could be because you have had cold sores your whole life. It could also be because you have HSV 1 infection in your genitals. Unfortunately, there is no way for you to know unless you actually develop symptoms in the genitals. How often people who are infected in the genitals with HSV 1 develop symptoms is discussed below.

  • How many people in the world actually carry Herpes?

HSV 1 – 80% to 90%. Oh yes. Scary thought. HSV 2 – 16% (This study is only for people between the ages of 19 and 49. It could be more if the age range was wider.) Yes it is extremely common. Which means universal screening for Herpes might not be too useful. In other words, if you do not have symptoms, you might not want to screen for Herpes as statistically, there is a good chance your test will turn out positive.

  • How many people develop symptoms?

When a person is first infected with HSV 1, 74% of them do NOT develop any symptoms. Same goes for HSV 2 except the number is a little lower at 63%.

As time goes by, 57% of people infected with HSV 1 in the genitals will develop symptoms. The number is much higher for HSV 2 at 89%. Those with HSV 1 infection of the genitals have a median of 1.3 outbreaks per year and those with HSV 2 infections of the genitals have a median of 4 outbreaks per year.

This means there are a good number of people infected with HSV that go through life happily oblivious of the fact.

  • What’s this thing about asymptomatic viral shedding?

That means even when a person does not show any symptoms, he/she is still shedding the virus and can infect someone else. Recent very smart studies using repeat genital sampling and spatial mathematical modelling have demonstrated that reactivations are brief (i.e. <12 h) and occur frequently. More specifically, 80% to 90% of people infected with HSV 2 undergo asymptomatic viral shedding in approximately 20% of days.

This means that many people are spreading Herpes without even realizing it. This makes it very challenging if not impossible to completely protect oneself from getting Herpes.

  • Should I screen for Herpes?

Hmm. No surprise the jury is still out on this one. In Singapore there is no recommendation for universal screening for Herpes. Similarly, in the US, screening is not recommended by the US Preventive Services Task Force. The reason given is that current blood tests are not all that accurate and that is a very fair statement. The other concern is that Herpes screening can lead to ‘detrimental psychological outcomes’. I definitely can relate to that. Many of my patients, completely well and asymptomatic, are driven to near madness because of a positive Herpes test. Of course when there is a clinical need, you should still screen for Herpes. The emotional and psychological aspect of it just has to be dealt with. However, universal screening for Herpes is still not recommended because there are no studies to actually show that people who know that they carry Herpes will change their behaviours to lower transmission rates.

If there is a good reason for you to screen for Herpes, please do it.

  • Any chance of a vaccine in the near future?

Sorry nope. Vaccine trials for Herpes has been nothing short of disappointing. Kinda like vaccine trials for HIV actually. There is a candidate for a Therapeutic Vaccine but it is only in Phase 1. Industry insiders will know to tell you not to hold your breath.

  • Conclusion

Statistically, it is more likely that you are carrying Herpes than not. If you develop symptoms like blisters or ulcers in the genital region, go see your doctor immediately. Swab tests of the blister or ulcers are much more accurate than blood tests for Herpes. There are medicines that you can take that will reduce the number of days you have to suffer with the symptoms. There are also medicines you can take to prevent outbreaks and reduce the risk of passing it on to your partner.

If you truly have been found to have Herpes don’t freak out. I know it sucks to be diagnosed with an STD that will stay with you for life but really things could be worse. At least Herpes is not going to kill you. It may cause you to have painful blisters or ulcers that can be controlled with medicines. It will not be passed to your children. The way infants are infected is if the mother has active Herpes blisters in the genital region at the time of delivery. If that is the case, your doctor can discuss alternatives with you like delivering the baby via a C-Section.

If you have Herpes don’t freak out. Manage the problem.

    Hi Doc,

    I have went for a blood test for HIV testing and my Hspv 2 was at the borderline 1.1. Anything above 1.1 is considered herpes positive. So I was prescribed Acyclovir tablets. Please advise should I go another testing say three mths or six mths time?

    • In my opinion the HSV 2 IgG test titer about 1.1 is not considered positive. This is a complicated topic. You should discuss it with your doctor who did the test for you.

  2. Good day Drs.
    worried sick about Herpes..8 days post exposure ( protected as far as i remember). i came down with a bad bout of frequent small volume urination. this lasted for approx 12 hrs and urination was back to normal but had on and off Dark urine for the next few days.. once again on the 18 day had the same bout of frequent short urination whic lassted for just 5 hrs. both these occasions my urination didnt burn. but my low volume and ocasion dark urine still persist. I am in the process of testing for HIV and 21 days later as of date have cleared the RNA and 21st day P24 antigen antibidy test.
    have also completed my Urine stds 10 days post exposure Gonnorea etc tested negative.. however the urine did indicate bacteria but the culture indicated no significant growth. also Pus+ Ketones ++ epithelial cells 15 wbc 1
    mucus 1.. proteins +*.. Am very concered as the culture showed no growth it could be a viarl such as herpes.. please help need your expert advice.. I am totally stressed out and sadly my alcohol consumption has.sky rocketed.
    thanking yoy kindly

    • What I can say is that your symptoms do not sound like Herpes to me. Whether or not you have Herpes can only be determined by screening tests. I suggest you go back to the doctor who did your initial tests for you to talk about your Herpes concerns.

      • Good day Dr.Tan,
        Thank you for your reply. Also a very big thank you for all your articles and forums.
        It has been a great source of comfort in this extremely stressful time.
        I will be dropping in nxt week to do the entire Std checks. (30 days).
        Sorry to repeat myself. But given my Urine parameters. Could the Dark urine be a lingering UTI or because of the presence of proteins could it be more so because of a kidney problem. given that there is no pain and the dark urine shows up every 3rd to 4th Pee..
        Thanking you again.

  3. Good day

  4. Good day Drs.
    worried sick about Herpes. i have completed all the urine based test and all is clear. my concern is that on the 8th day post exposure i had a bout of frequent urination and this lasted for about 12 hours.. the symptoms stopped but slight irritantion and on and off dark urine persisted.. 18 days post exposure had the same episode of urination and it too lasted for just 5 hrs.. however dark urine on and off dark urine still persist. my urine culture 11 days post exposure indicated no growth however there was bacteria in urine.. with wbc 1. epithelial cells were high 15. ketones high and proteins +* also plus +. worried if this could be the signs of Herpes.. besides the urination problem no other signs.. please advise.. thanking you

  5. Recently I had done a HSV type 1 and 2 lgG Ab test. I had a 3.21 result for type 1 and 0.29 for type 2. What does the result mean? Is my type 1 highly contagious? I have never have cold sore on my lips but had at one period had serious acne outbreak at my chin area more than 10 years ago which I thought was due to late night sleep. It is already healed and no recurrence after that period. I am having a new man in my life and is worrying about the herpes transmission to him.

    • I’m surprised your doctor did not explain this to you. HSV 1 is very common and it usually affects the mouth region. You can also get it in the genital area. It is difficult to tell unless you have had symptoms before.
      It is best to speak to your doctor about this and discuss what you can do to reduce the risk of transmission.

  6. i read online that herpes rash will heal after some days and disappear. but can a rash that has no symptom and that stays more than 16weeks be herpes?

    • How can a rash have no symptoms? A rash is a symptom. I don’t understand your question.

      • hi doc,

        i mean apart from appearance of the rash there is no other symptom like pain. so was wondering whether a rash that stays for more than 16weeks can be herpes or some other thing like bacterial or fungi.infection.

  7. I’ve been diagnosed with HSV-1. The lab results came back and sadly it was positive, however are you guys able to prescribe suppressive therapy? If so, i would like to book an appointment.

  8. Hello Doc,

    On a medical checkup for my work I had an IgG HSV 2 test come back positive, with a measure of > 200 U/mL. For info, IgG HSV 1 also came back positive – which am really not so concerned about, but both IgM tests for HSV 1 and 2 came back negative.

    I have never shown any symptoms in my life, and in 2009 my wife and I were also tested, and my results for IgG HSV 2 were negative (albeit on that test, at a different hospital, the results were given using an index figure (although the results don’t show the number, only that I fell within the negative range)). Just as for this recent test both my wife and I were tested, and her results for HSV 1 and 2 are both negative.

    I have not had any extramarital affairs, so there has been no ‘funny business’, so am very confused as to how I can now be positive for HSV 2 (or rather, am now showing antibodies present for HSV 2), when my last results from 2009 show that I had no infection?

    Therefore I would like to ask if you had any thoughts on this? I am also not sure on how to compare the U/mL results to that of index figures, so am unable to see if the possibility of a false positive is more or less likely.

    Lastly, we are actually based in Indonesia, but would be very willing to travel to your centre if you think there might be a possibility that this could be a mistaken result.

    Thank you,

    DD

    • It is difficult to comment based on what you described. You had 2 tests at different hospitals and different labs. The best way to go forward is to get yourself re-tested again to be absolutely sure. False negative/false positive result is a possibility. The other possibility is that when you did your first test, you just got infected therefore IgG was still negative.

      • Thank you Doctor. I really appreciate that you have created and are active in this forum – it’s very helpful, obviously for many people.

        If I may ask, given that I was last tested in 2009, and have only been with my wife since then – is it possible that after 7 years that she has not contracted it from me, since we are not regularly using protection? And if it is possible, are you able to comment on the likelihood of the virus not having spreading to her? I realise am asking for speculation, and over the internet no less, but everything I’ve read seems to suggest that the transmission risk is high, even in those without symptoms. So if it is very unlikely that she would not by now also be positive, I’m looking to get on the next plane to SG to get tested there.

        Any advice you could share would be much appreciated. Thank you.

        • Getting yourself tested again is the right thing to do. There is no point asking yourself all these questions because you are not even sure if the test results were reliable.

  9. Hi Doctor,

    I recently did the blood test and i found out the herpes 2 igG result is borderline 1.0. I am wondering whether the test is accurate. Is it mean i have this virus?? I am worrying of it so much!! will the test be fasle-positive? My doctor gave me Acyclovir 7 days treatment and asked me to draw the blood for testing in early May. But i saw some forum and stated their doctor wont have any treatment for borderline.

    Thanks!

  10. Hi, recently I develop some blisters wearing my New shoes. But suddenly recently my legs became itchy and develop some itchiness on my foot and foot sore.

    Even my outer Anus side became itchy. I’m not sure whether it is due to the weather and I have eczema history. Can I have some advice?

  11. hi dr tan

    My recent lab results for HSV-1: 0.07 and HSV-2: 1.77. I was totally shocked when the doctor told me I was positive for herpes. I read from you earlier reply was that anything < 3.5 might yield false positive results. May I ask what other tests can I opt for to confirm that? Thanks.

  12. Worried

    3 weeks ago I fingered a sex worker and had ulcers in my mouth. Now I’m very worried that I have herpes as I had put the finger in my mouth. No symptoms at all till now but I am freaking out. Does mouth ulcers increase the chance of getting herpes? Also, 3 months ago I had swollen lymph node on my neck. Could it be caused by herpes as well?
