A statement from the UK Family Planning Association said genital herpes is carried by many tens of thousands of people who do not know they are carrying it because they have never had an attack or if they have it has been only a minor attack amounting to a mild sore throat and perhaps microscopic blisters in the genital area...
Genital herpes is caused by a virus that lives or lies dormant in the nerves and is related to that causing cold-sores, chicken pox and shingles. Like those other things it is only infectious while the sufferer is having an attack...
Just as you wouldn't kiss someone with an active cold-sore for fear of catching it, you shouldn't have sexual contact with a genital herpes sufferer while they are having an attack...
In many cases it will be obvious an attack is taking place from the presence of blisters that will sometimes have the appearance of a weeping cold sore but, according to the news report, can have many appearances ranging from tiny white pimples to the above and, as previously mentioned, might not have any outward signs that are visible at all!
Other than never having contact with a sufferer there is really no foolproof method of avoiding catching the virus, though the sensible precautions of having a good look around your partner's genital or oral area under a strong light and with a magnifier and quizzing them about sore throats and general state of health might shift the odds in your favour.
To the best of my knowledge only the use of the femidom provides any physical protection against infection.
I hope this will have prompted a list of questions to put to your doctor when you see him.
Just as with cold sores, genital herpes sufferers can manage the condition more easily and reduce the number of attacks by concentrating on their general good health and well-being.
