title: Rapid contamination of the environments with varicella-zoster virus DNA from a patient with herpes zoster.
abstract: Patients with zoster are considered to be less contagious than varicella patients because their infection is localised. It is not known, however, when and for how long a spread of varicella-zoster virus (VZV) from a zoster patient begins and continues and the extent of virus spread from the patient. The polymerase chain reaction (PCR) was used to detect VZV DNA in samples obtained from the hands and throat of a patient with zoster and from her room environments including surfaces of the back of a chair, the door handle, the table and the air conditioner filter. VZV DNA was detected on the surfaces of the back of the seat and the table and in peripheral blood mononuclear cells (PBMCs) and serum on Day 4 of the illness. VZV DNAemia persisted for 4 days until Day 7 of the illness. It was also detected in samples collected from throat and the air conditioner filter on Days 6 and 7 of the illness respectively. All of the surfaces, that were examined in her home environment, were contaminated with VZV DNA by Day 7 of the illness. The present study showed rapid and wide spread of VZV DNA in the environment even from a patient with zoster.
