Epidemiologic aspects of recurrent herpes labialis among Jordanian University students

To study the epidemiologic aspects of recurrent herpes labialis (RHL) in a young adult population and to evaluate treatments used by affected patients.

A cross-sectional survey conducted on a random sample of 1000 students of The University of Jordan, Amman, Jordan between May and September 2008. Subjects with RHL were identified and asked to describe their disease and its management. Chi-square and t-test were used to compare differences between groups.

The point prevalence of RHL was 2.3%, annual prevalence was 17%, and lifetime prevalence was 26.4%. The prevalence was related to the place of living, income, and college, but not to gender, marital status, medical history, smoking, or aphthous stomatitis. Eruptions occurred mostly on the left side of the lower lip and systemic upset, stress, and cold weather were the main triggering events. The mean age of onset was approximately 15 years. Of the cases, 51.2% reported at least 2 recurrences annually and 61.7% had positive family history. Nearly one-half of cases have treated the lesions and only 18.2% have used antiviral therapies. Some used lipstick, vaseline, tahini, or toothpaste to cover lesions. Treatment was recommended mostly by relatives and friends, only 26.3% sought treatment advice from medical practitioners.

A high prevalence of RHL among this population was found. There is a need to educate patients with RHL on treatment options available to reduce their distress and to improve their quality of life.
