Mis-information - Just Some Facts
It has been suggested that a cold sore is not Herpes in this thread. That is inacurate. Cold sores are caused by the the Herpes HSV-I virus and the medical community estimates that up to 90% of the population over 50 years of age has contracted this virus - see below.
Not as serious as Herpes HSV-II (genital herpes), it can be transferred to other parts of the body (including the genitals) and the virus cannot be irradicated from your body.
The Herpes outbreak referred to in this Thread is a general warning that you will hear at the STI Clinic when you go for testing and according to my sources there is no register of infected SP's at MP's and there is no banning by licensing as they have no means to be informed and would be on very difficult legal grounds because Herpes HSV-I is so widespread.
It has been mentioned to me that BLE is simply passing on the STI Clinic warning because SP's and their clients have a higher risk of contracting the infection. It is not a situation where BLE has identified that the SP's at MP's are causing a break out of the infection.
The Facts About Cold Sores
By Stuart Maddin, MD, FRCPC
Cold sores, or fever blisters, are common among Canadians.
Read the facts about cold sores and the virus that causes them. Cold sores are caused by the Herpes HSV-1 virus which is very widely spread. North American
Fact:
Cold sores are caused by the herpes simplex virus. There are two types of this virus and cold sores are usually caused by type 1 (known as HSV-1). The other type of herpes simplex virus, HSV-2, usually causes genital herpes
In general, we are infected with HSV-1 when we are children; in the majority of these initial (“primary”) infections, there are no symptoms
Usually, the virus infects our mouths. Some children experience mouth and gum symptoms (“gingivostomatitis”) or a sore throat (“pharyngitis”).
Fact: Cold sores are the result of the virus reactivating in our bodies
Once HSV-1 has entered our bodies, it never leaves. The virus moves from the mouth to quietly reside (“remain latent”) in the central nervous system.
In approximately one third of people, the virus can “wake up” or reactivate to cause disease
When reactivation occurs, the virus travels down the nerves to the skin where it may cause blisters (cold sores) around the lips, in the mouth or, in about 10% of cases, on the nose, chin, or cheeks
Many people who suffer from cold sores are aware in advance that a cold sore is about to break out — they have a tingling or burning feeling, redness, itching, or pain (“prodromal symptoms”) around their lips or mouth
Cold sore outbreaks may be influenced by stress, menstruation, sunlight, sunburn, fever, or local skin trauma.
Fact: The virus that causes cold sores is infectious
30%-60% of children below 10 years of age are infected with HSV-1. They have acquired the virus from family and friends through sharing utensils or toothbrushes, and from kissing
The virus is transmitted from cold sores and also when there are no symptoms, as it can make copies of itself on the skin in the absence of a blister. This phenomenon is called “asymptomatic shedding”
By 50 years of age, 80%-90% of us harbour HSV-1 because we have caught it from someone close to us
HSV-1 can sometimes be transmitted to newborn babies by family members or hospital staff who have cold sores; this can cause a severe disease called neonatal herpes.
Fact: The virus from cold sores can infect other areas of the body
People can transfer the virus from their cold sores to other areas of the body, such as the eye, skin, or fingers; this is called “autoinoculation”
Eye infection, in the form of conjunctivitis or keratitis, can happen when you rub the cold sore, then rub your eyes before washing your hands
Finger infection (“herpetic whitlow”) can occur when a child with cold sores or primary HSV-1 infection sucks his/her fingers
HSV-1 can infect your genital area if you engage in oral sex with a partner with a cold sore
Fact: Early treatment can help eliminate the cold sore
Some products can accelerate healing if they are used at the prodromal stage of the cold sore
Prescription drugs include acyclovir cream or capsules (Zovirax®) and penciclovir cream (Denavir®); also, Health Canada recently approved a one day course of 2 grams valacyclovir caplets (Valtrex®) for prodromal use
Docosanol cream (Abreva®) can be bought without a prescription
Frequent hand washing minimizes the risk of transferring the virus to other areas of your body
