Abstract: The invention provides an automated hand hygiene/infection control monitoring sensor-based system suitable for improving hand hygiene and multiple infection control measures and ensuring compliance by health care workers as well as visitors to hospitals and clinics. The use of biometric identification devices such as cameras for face recognition and profiling, microphones for voice recognition, etc. permit highly accurate identification without the use of removable identification devices such as identification badges which may include bar codes, magnetic strips or wireless devices such as RFIDS. Identification badges are removable and hence susceptible to being lost, misplaced, etc. Visitors are typically not assigned identification badges and hence enforcement of hand hygiene policies is minimal.
