Recurrent herpes labialis in skiers

Abstract

Recurrent orofacial herpes infection may be triggered by high altitude skiing, presumably because of solar ultraviolet radiation exposure. Six (12%) of a group of 51 subjects with a history of skiing-triggered herpes observed during 1 week of high altitude skiing experi enced reactivations of orofacial herpes a median of 3¹/₂ days after exposure. Within this group, application of a sunscreen with a sun protection factor (SPF) of 15 failed to influence the reactivation rate as compared with a placebo.

Reactivation of herpes triggered by skiing is common. As application of a sunscreen with an SPF of 15 did not appear to influence the reactivation rate, alternate approaches to the control of recurrent orofacial herpes are needed.
