We prospectively studied all herpes simplex labialis (HSL) episodes in a group of 84 (age, 6 to 71 years) persons who previously had frequent recurrences of HSL to determine whether their recurrences of HSL were different from those of the general population. The mean +/- standard error for number of HSL outbreaks for 6 months was 2.7 +/- 0.3. Age, gender, or season did not influence the recurrence rate. The mean time to vesicle healing of 214 outbreaks was 6.4 +/- 0.2 days. Again, age or gender did not influence healing time. An episode of HSL did not elicit a refractory period to the next attack of HSL. Furthermore, the severity of the previous HSL lesion did not influence the interval to next recurrence or the location of the next lesion. In 47%, the next recurrence of HSL crossed the midline of the face, and in 45%, it moved from one lip to the other. The high recurrence frequency and multiple facial locations of HSL lesions seen in these persons differed from the general population, who report infrequent lesions of HSL at the same facial location.
