title: Herpes labialis among dental healthcare providers in Nigeria.
abstract: BACKGROUND
  The epidemiology of herpes labialis has been relatively neglected. The objective of this study was to determine the prevalence and risk factors of self-reported herpes labialis among Nigerian dental health providers.
  
  
  METHODS
  This cross-sectional study of final year dental students and dentists undergoing postgraduate training at University of Benin Teaching Hospital, Benin City, Nigeria was conducted in June, 2014. The demographic information, lifetime and period (previous year) experience of the herpes labialis, perceived triggers and action taken during the last episode were obtained using a self-administered questionnaire.
  
  
  RESULTS
  The annual prevalence of herpes labialis was 7.4% while the lifetime prevalence was 22.1%. The lifetime prevalence was significantly associated with marital status, professional status and family history of herpes labialis. However, in binary regression, it was only marital status and family history of herpes labialis that emerged as the determinants of this lifetime prevalence. The most common trigger factors reported by the participants for the last episode of herpes labialis were fever, malaria, fatigue and stress. The actions taken by participants for the last episode of herpes labialis were using drugs without prescription (14.3%), application of lubricant (23.8%), nothing (57.1%) and could not remember (4.8%).
  
  
  CONCLUSIONS
  Data from this study revealed that one out of fourteen and one out of five every studied dental healthcare providers had experienced herpes labialis in the last 12 months and their lifetime respectively. The reduction of fever inducing infections, stress and fatigue which were major triggers will help decrease herpes labialis among this studied group.
