Despite regular disinfection procedures in hospitals, surfaces can be continuously re-contaminated due to high patient traffic, patient and staff use, and intense contact in common areas. Scientific research shows the presence of 60 different potential pathogenic microorganisms, such as Staphylococcus aureus, Enterococcus spp., Escherichia coli, and Klebsiella aerogenes, on "high-touch surfaces" like door handles, bed rails, patient bed headboards, infusion pump/monitor surfaces, nurse station keyboards, stretcher/wheelchair handles, elevator buttons, waiting area chairs, counter/table surfaces, sinks, toilet doors/handles, and cleaning material boxes. These findings indicate that a significant amount of microbial load still remains on many surfaces despite routine disinfection.
For example, taking a waiting room chair (seat + backrest) as a large surface, if calculated based on an equivalent "high-touch surface bacterial load" measured in a hospital, there is a possibility of hundreds of thousands of live microorganisms on the entire surface. This microbiological load indicates that the risk of infection, especially for immunocompromised individuals, should not be overlooked.
By carrying Sterilisa Pro or Sterilisa Mini with you when going to the hospital, individual disinfection can be provided on high-touch surfaces (such as door handles, chairs, elevator buttons, bed rails, stretcher handles). Thus, the "surface → hand → body / items" chain can be broken, reducing the risk of contracting other diseases and supporting the immune system by reducing the additional microbiological load.
