2. Recurrent Oral Herpes Most patients have only a couple of outbreaks a year, although a small percentage of patients experience more frequent recurrences. HSV-2 oral infections tend to recur less frequently than HSV-1. Recurrences are usually much milder than primary infections and are known commonly as cold sores or fever blisters (because they may arise during a bout of cold or flu). They usually show up on the outer edge of the lips and rarely affect the gums or throat. In most cases there are local, highly contagious vesicles on the lip or at the gingiva. 3. Etiology: Factors which triggers the reactivation of the virus: 1. Fever 2. Cold 3. upper respiratory infection 4. exposure to the sun or cold air 5. Fatigue 6. Menstruation 7. UV light exposure 8. psychic stress 4. Diminished host resistance is the common precipitating factor for the reactivation of Herpes Simplex Virus (HSV). 5. Clinically.. Some patients get an Aura sensation (they are able to sense that a lesion will soon develop. Lesions starts out as vesicles and maybe fleeting vesicles. Occurs particularly on the bound down mucosa which is attached to the periosteum. 6. Treatment/Prognosis: Topical Acyclovir can be prescribed. Acyclovir serves to shorten the duration of the disease by one to two days. Instruct patient for proper nutrition, oral care, appropriate fluid intake. Prognosis is self-limiting. 7. The End.
