Canker sores are sometimes thought to be caused by HSV, but this is not true. Canker sores occur only inside the mouth, on the tongue, and on the soft palate (roof of mouth), not on skin surfaces. Although they reoccur, they are not contagious, usually are self-limiting, and have almost no complications. Canker sores are caused by substances that irritate the lining of the mouth.
HSV-1 infections can be treated with antiviral medication, such as acyclovir. These medication cannot cure the infection. But, they can help reduce the severity and frequency of symptoms. Prosurx is one of the best antiviral creams for cold sores. It is famous for treating symptoms and preventing outbreaks in the future. For this, you are recommended to apply Prosurx to the sores 2 to 3 times a day. Factors like stress, colds, fever and certain foods may trigger HSV-1 infections. To prevent an outbreak, you need to avoid these triggers.
The herpes simplex virus is probably the most well-known virus of the herpes family, and it is just as contagious. Herpes simplex infects epithelial cells and remains latent in neurons. HSV-1 causes recurrent oropharyngeal lesions, commonly known as “fever blisters" or "cold sores.” It is also the primary cause of sporadic encephalitis (inflammation of the brain), gingivostomatitis (inflammation of the gums and mucous lining of the mouth), and keratoconjunctivitis (severe dryness of the eye that involves the cornea) and dendritic corneal ulcers (also called HSV keratitis) in which the cornea becomes affected by herpetic lesions that look like the dendrites of neurons in the brain.
