For most people, the diagnosis of genital
herpes (Herpes Simplex Virus 2 or HSV2) is a shock. For others,
the diagnosis maybe a confirmation of suspicions they have had
about their own health or their partner's behavior. Seeking to
answer the question of how the patient contracted the condition
often leads to a search for blame and then self-recrimination.
Living with herpes is something that initially may take some
psychological adjustment for some patients. It need not mean
the end of your sex life or that you will need to remain
celibate for the rest of your life.
Firstly HSV2 and HSV1, better known as the cold sore virus, are
just two of a related group of seven viruses that are known to
infect humans. Others include the Varicella-Zoster virus,
commonly known as chicken pox and shingles. Diagnosis of
infection with either HSV1 or 2 can be established with a blood
test known as the Western Blot test; the upside of this test is
that a patient who does not have active lesions may be
diagnosed through the presence of antibodies to either strain.
Accuracy of this test is only 90-95% depending on the lab
involved. Some instances have occurred where patients were
diagnosed with either a false positive or a false negative. The
most accurate diagnosis is with a physician taking the top off
a fresh lesion, obtaining a swab from the base of the lesion
and a lab growing a viral culture from it. Extracting a viable
swab from the lesion can be quite painful for the patient.

HSV2 traditionally involved
infections in genital areas, with the virus
lying dormant in the sacral nerve at the base
of the spine during periods when the patient is
not experiencing lesions. HSV1 traditionally
involves infections around the mouth and nose
and lies dormant in the trigeminal nerve in the
neck during non-active phases of the disease.
Current epidemiology studies across the Western
World indicate the incidence of HSV2 to be
around one in eight people, or 12% of the
population. Only one in five of those with
antibodies have been diagnosed.
In real terms, in a room containing forty
people, five have HSV2 but only one knows they
have it. A further three of the five may have
had an isolated symptom once or twice. This
would have appeared so insignificant that they
mistook it for a pimple, infected hair follicle
or a boil. The final one in five is someone who
has never had a symptom and may never do so.
For this patient, and the other three
undiagnosed patients, accusations of infection
(generally followed by accusations of
infidelity) from a partner are often met with
counter accusations and disbelief. A
conservative estimate of the world population
with HSV1 antibodies and the ability to infect
others is around 90%. Of these, roughly 45% are
symptomatic. If you have been diagnosed with
either infection, it is very possible you
contracted it from someone who has no idea they
have it themselves.
People have received the messages about safe
sex and changed some of their practices,
believing that only penetrative sex requires
safe sex. Sexual health specialists now report
that half the new HSV diagnoses in clinics have
been microbiologically confirmed as HSV1 on the
genitals, in the general community it is now
estimated that 20% of all herpes infections in
the genitals are in fact HSV1. On the plus side
for the infected patient, when the HSV virus is
not living in its ideal host environment (i.e.
HSV1 infection of genitals, oral HSV2
infection) infections have been generally
documented to be less severe and happen less
frequently.

Another mistake many patients make, is
assuming that they are not infectious during a dormant or
asymptomatic phase of their disease. Studies have shown that
even when a couple who are clinically discordant (i.e. one is
positive and the other is negative) use what is recognized as
gold standard treatment for reduction of risk to partners, the
rate of transmission in a 12-month period is still 10%. This
management of infection control involves the use of condoms
during all sexual encounters and complete abstinence from sex
during the positive partner's symptomatic phases.
Interestingly, sexual health experts report that if one partner
has remained negative for 10 years in a clinically discordant
partnership, it is very unlikely that they will contract the
disease after this time. It is speculated that they have some
immunity/protection either natural or acquired that science has
not yet managed to identify.
A true primary infection of HSV2 can last for up to ten days,
it involves a systemic response, where all the glands in the
body are swollen, much as if the patient has influenza, as well
as the obvious genital burning, itching, pain with urination or
complete inability to urinate. Many patients think they are
presenting with a primary infection, but, severity of symptoms
indicates to the physician, this is in fact a recurrence. In
these cases the patient's primary infection would have been
asymptomatic, but, for some reason, they have become run down
and their immune system is not responding as it did when they
were first infected. These and subsequent recurrences of HSV2
are usually around five days in duration, unless there is a
serious immune system deficiency. In this case, the treating
physician should refer the patient for further testing.
Because HSV transmission requires skin-to-skin contact and
viral shedding to occur, typically an infection of HSV2 is
specifically confined to the genitals. Affected areas include
the vulva and labia in women and penis and scrotum in men, due
to penetrative intercourse being quite localized. Where a
patient has been infected with HSV1 on the genitals, the area
is usually larger and vesicle distribution more extensive due
to oral sex skin-to-skin contact covering a more extensive
surface area of the genitals. Both viruses may be treated
effectively with anti-viral drugs.
As stated earlier, each virus has its ideal host environment.
For the patient infected with HSV1 on the genitals, this means
subsequent infections are usually less virulent, and in some
cases may only ever recur once or twice in their lifetime. For
the patient infected with HSV2 on the genitals, the incidence
of recurrence can vary greatly. Recurrences are related to the
health of the immune system. Triggers may include stress, poor
diet, lack of sleep, sunburn and in some women, their menstrual
cycle. During the first year of infection, the number of
recurrences may range from one to twelve, with an average being
four to five. During subsequent years the immune system
responds better, the patient learns what will trigger a
recurrence and usually tries to avoid it. Eventually most
patients can experience as few as one to two recurrences per
year. Also, as the patient learns to better recognize the
symptoms of an impending recurrence, they are able to
administer anti-viral drugs earlier. This can minimize the
length and duration of the attack, and possibly prevent lesions
altogether. It is important for the patient to remember that
despite avoiding a recurrence, they are still shedding the
virus and they are still potentially infectious to their
partner.
Maintenance doses of anti-virals may be taken daily to reduce
the number of recurrences. Up to 50% of patients on these
therapies report an absence of recurrences in a 12-month
period. Where this therapy is discontinued, patients almost
certainly will experience a recurrence within three weeks. This
is generally followed by a reduction in the number of annual
recurrences. There are a small number of female patients who
have required this maintenance therapy with anti-viral drugs
continuously since they first became available, over 15 years
ago, in earlier forms. As recurrences reduce in frequency and
severity, most patients eventually come to terms with their
diagnosis. For some, this is never the case, sexual health
physicians report that they need to refer between 10-20% of
their patients for further psychological counseling. This is in
spite the fact that they are very experienced with the disease
counseling required for this diagnosis.

What is important,
regardless of how well patients appear to cope
with the initial diagnosis, is ensuring access
to information. This can be obtained readily
and anonymously from www.herpes.com,
www.herpeshelp.com or www.genitalherpes.com
these sites contain up to date facts and also
links to other sites. These provide names and
contact details of support groups, local
clinics and sexual health specialists. Although
HSV2 is a lifelong infection, with the right
management and care it is not necessarily
symptomatic, nor should it impede the patient
from enjoying a loving and long-lasting, secure
relationship.
