Cold sores, also called fever blisters, are a highly contagious viral infection that spreads through contact. Although it is highly contagious, having the viral infection doesn’t mean it will affect daily life. As discovered in a study done by the World Health Organization, about 67% of the global population under the age of 50 has HSV-1, or herpes simplex virus - 1, the cold sore virus that causes oral herpes. Despite it being so present in our society, most people never exhibit symptoms of herpes simplex simply because their body can control the virus. They are not to be confused with canker sores which happen inside the mouth due to stress, hormones, biting yourself, or allergies. A dermatologist can visually identify cold sores as a result of HSV from the symptoms. There are two types of HSV: herpes simplex virus type 1 (HSV-1) and sometimes the herpes simplex virus type 2 (HSV-2). Further testing on the patient’s blood or the cold sore fluid may be done on patients with a weakened immune system. Our care team will help you achieve your perfect health!
