An estimated 2 million people contract health-care associated infections on a yearly basis, according to the CDC, resulting in nearly 100,000 deaths and, per the National Center for Biotechnology Information, between $30 billion to $45 billion in expenses to hospitals nationwide. The CDC-funded "Benefits of Enhanced Terminal Room Disinfection" study found the use of a disinfection robot may have a major impact on those numbers, with a robot cleaning "decreas(ing) the relative risk of colonization and infection of target multi-drug resistant organisms among patients admitted to the same room by a cumulative 30% in a hospital setting, with 93% compliance of standard disinfection protocols."
