Inactivation of influenza A virus on copper versus stainless steel surfaces.
Influenza A virus particles (2 x 10(6)) were inoculated onto copper or stainless steel and incubated at 22 degrees C at 50 to 60% relative humidity. Infectivity of survivors was determined by utilizing a defined monolayer with fluorescent microscopy analysis. After incubation for 24 h on stainless steel, 500,000 virus particles were still infectious. After incubation for 6 h on copper, only 500 particles were active.
