Low amperage direct electric current inactivates HSV-1 & Adv-5

The purpose of this research was to investigate the effect of constant direct current (DC) on the viral infectivity (Herpes Simplex Virus type 1 & Adenovirus type 5) without using antiviral agents or other chemical disinfectants in vitro. It was found that direct current (200uA in 10 minutes) fully inhibited viral infectivity. 
The applied current density in the above experiments was 20uA/mm² delivered from platinum electrodes.
