The present study describes control methods for influenza virus. We verified the effect of slightly acidic electrolyzed water on influenza virus in both fluid condition and aerosol condition. By the hemagglutination test and the TCID50 test, it was confirmed that virus lost its viral activity drastically. In addition, we introduced the new system adopted electrolyzed water into school facilities. Experimental results showed the effect of keeping adequate relative humidity and decreasing airborne common bacteria and fungi.
