Mouth Disease - Herpes

Herpes

Another very common disorder of the oral cavity is herpes simplex infection (HSV). This virus causes blisters and sores around the mouth and lips. HSV infections are not only annoying but also painful and may keep on recurring. Although many people get infected with the virus, only 10% actually develop the sores. The sores may last anywhere from 3–10 days and are very infectious. Some people have recurrences either in the same location or at a nearby site. Unless the individual has an impaired immune system, e.g., owing to HIV or cancer-related immune suppression, recurrent infections tend to be mild in nature and may be brought on by stress, sun, menstrual periods, trauma or physical stress.
