A method for protecting individuals from spreading infections in medical, social and public facilities, the method comprising: defining at least one antinfection zone with specific antinfection requirements for different individuals in this zone; carrying out an antinfection practice before entering the antinfection zone for protecting hands and, optionally other exposed body parts, of an individual against infections; said antinfection practice comprising: coating the hands and other exposed body parts with a antiseptic skin spray containing calcium fluoride; subjecting the hands and other exposed body parts with a sprayed matrix of polymers; using an antinfection device at the entrance of the antinfection zone to apply antinfection practice to the hands and other exposed body parts of an individual; wherein sensors in the device identify individuals, assess the antiseptic efficacy of the antiseptic skin coating by counting the free suspended negative ions from the calcium fluoride using fluorescence measurement and determine the effective antinfection time afforded by the coating; wherein a computer system in the device records the identity, antiseptic efficacy and antinfection time said information being recorded as an individual's antinfection profile in a database; and controlling the antinfection practice using an embedded computer system. defining at least one antinfection zone with specific antinfection requirements for different individuals in this zone; carrying out an antinfection practice before entering the antinfection zone for protecting hands and, optionally other exposed body parts, of an individual against infections; said antinfection practice comprising: coating the hands and other exposed body parts with a antiseptic skin spray containing calcium fluoride; subjecting the hands and other exposed body parts with a sprayed matrix of polymers; using an antinfection device at the entrance of the antinfection zone to apply antinfection practice to the hands and other exposed body parts of an individual; wherein sensors in the device identify individuals, assess the antiseptic efficacy of the antiseptic skin coating by counting the free suspended negative ions from the calcium fluoride using fluorescence measurement and determine the effective antinfection time afforded by the coating; wherein a computer system in the device records the identity, antiseptic efficacy and antinfection time said information being recorded as an individual's antinfection profile in a database; and controlling the antinfection practice using an embedded computer system. coating the hands and other exposed body parts with a antiseptic skin spray containing calcium fluoride; subjecting the hands and other exposed body parts with a sprayed matrix of polymers; using an antinfection device at the entrance of the antinfection zone to apply antinfection practice to the hands and other exposed body parts of an individual; wherein sensors in the device identify individuals, assess the antiseptic efficacy of the antiseptic skin coating by counting the free suspended negative ions from the calcium fluoride using fluorescence measurement and determine the effective antinfection time afforded by the coating; wherein a computer system in the device records the identity, antiseptic efficacy and antinfection time said information being recorded as an individual's antinfection profile in a database; and controlling the antinfection practice using an embedded computer system.
