Herpes simplex virus dispersal by Hyfrecator® electrodes

The dispersal of herpes virus by electrodes has been studied. A Birtcher Hyfrecator® electrode was used to treat skin biopsy samples to simulate the clinical setting. Discharge of the electrode over a drop of dye demonstrated that droplets can be showered over 5 cm. The virus could survive on a contaminated electrode at room temperature for at least 5 min. Contaminated electrodes were not sterilized by electrical discharge, and virus transfer to skin samples was demonstrated after contact treatment. Virus could not be recovered from probes after treating contaminated skin samples. We conclude that it is essential to sterilize probes between patients to avoid transmission of infection.
