In this method a hand is inserted into a Hand Hygiene Hub. The presence of the hand and/or a pathogen on the hand is sensed of a subject. In response to the pathogen and/or hand's presence being sensed, the inserted hand is automatically irradiated with 222 nm Ultraviolet-C light within the Hand Hygiene Hub. The hand is irradiated for a predetermined period of time that is set based on a type of the pathogen sensed. ## Claims ### Claim 1 A method for disinfecting the hands of a subject comprising: inserting one or more body parts in a hand hygiene hub; sensing the presence of a one or more pathogens on a hand of a subject; and automatically irradiating the inserted hand with Ultraviolet light within the hand hygiene hub for a predetermined period of time based on a type of the one or more pathogens sensed. ### Claim 2 (depends on 1) The method as recited in claim 1 further comprising: identifying the type of the one or more pathogens sensed with a controller using pattern recognition. ### Claim 3 (depends on 2) The method as recited in claim 2 wherein the ultraviolet light is emitted at 222 nm. ### Claim 4 (depends on 1) The method as recited in claim 1, wherein sensing the presence of a one or more pathogens on hand includes using one or more ultrasonic transducers transmitting in the sonic range to sense the presence of the one or more pathogens. ### Claim 5 (depends on 1) The method as recited in claim 1, wherein sensing the presence of a one or more pathogens on the hand includes using multiple ultrasonic transducers transmitting in the sonic range and placed in array pattern to sense the presence of the one or more pathogens. ### Claim 6 (depends on 2) The method as recited in claim 2 further comprising: transmitting a signal indicating the identified pathogen type to a processing device; and displaying to a user with the processing device the identified pathogen type. ### Claim 7 (depends on 2) The method as recited in claim 2 wherein automatically irradiating the inserted hand with Ultraviolet light within the hand hygiene hub includes automatically irradiating the inserted hand with multiple ultraviolet light sources within the hand hygiene hub, and placing a least one of the UV light sources below the hand and another of the UV light sources over the hand within the hand hygiene hub. ### Claim 8 A Hygiene hub comprising: a plurality of walls forming a chamber with opening to receive a hand of a subject; one or more sensors coupled with the plurality of walls to detect within the chamber the presence of one or more pathogens present on the hand of the subject; and an ultraviolet light source operative to emit 222 nm ultraviolet (UV) light onto the hand of the subject in response to the one or more sensors detecting the presence of one or more pathogens present on the hand of the subject. ### Claim 9 (depends on 8) The hub as recited in claim 8, further comprising a controller and an archive library stored in a memory of the hub to identify a type of the one or more pathogens using pattern recognition. ### Claim 10 (depends on 9) The hub as recited in claim 9, further comprising a controller operative to set the time the UV light is emitted based on the pathogen type. ### Claim 11 (depends on 10) The hub as recited in claim 10, wherein the one or more sensors include multiple ultrasonic transducers transmitting in the sonic range and are placed in array pattern to sense the presence of the one or more pathogens. ### Claim 12 A method for disinfecting one or more body parts of a subject comprising: placing the one or more body parts adjacent a hygiene device; sensing, with an ultrasonic transducer coupled with the hygiene device and transmitting in a subsonic range, one or more pathogens on the one or more body parts; identifying, using a controller coupled with the transducer, a type of the one or more pathogens on the one or more body parts; and irradiating the one or more body parts with 222 nm Ultraviolet light for a predetermined period of time, the predetermined time set based on the identified type of the one or more pathogens. ### Claim 13 (depends on 12) The method as recited in claim 12 wherein sensing the presence of a one or more pathogens on the one or more body parts includes using multiple ultrasonic transducers transmitting in the sonic range and placed in array pattern to sense the presence of the one or more pathogens.
