    Abstract:
    We have investigated whether the copy number of varicella-zoster virus (VZV) in saliva correlates with the clinical symptoms in patients with Ramsay Hunt syndrome. A real-time quantitative polymerase chain reaction assay was used to examine the VZV DNA copy number in saliva samples from 37 patients. We detected VZV DNA in 6 of the 7 patients with oropharyngeal zoster lesions (86%) and in 17 of the 30 patients who had zoster lesions only on the skin (57%). Patients with oropharyngeal zoster lesions had a high VZV load in their saliva, and the difference between the copy number in patients with oropharyngeal zoster lesions and those without was around 10,000 copies per 50 microL. In addition, patients with oropharyngeal zoster lesions showed worse recovery of facial function than those without. It seems that the VZV DNA level in saliva reflects the kinetics of viral reactivation in the facial nerve, as well as in the oropharyngeal epithelium, in patients with Ramsay Hunt syndrome.
