This will allow for healthcare workers to create a disposable added layer of protection to their surgical masks, N95s, or homemade masks by using household available products.Background Manual disinfection of medical devices is prone to failure. Disinfection by aerosolized hydrogen peroxide might be a promising adjunctive method. We aimed to assess effectiveness of dry mist of hydrogen peroxide (HPDM) on noncritical medical equipment. Methods One cycle of HPDM was applied on a convenience sample of 16 different types of "ready to use" noncritical medical devices in a closed, but nonsealed room. Of every object, 2 adjacent areas with assumed similar bacterial burden were swabbed before and after HPDM deployment, respectively. After culturing, colony forming units (CFU) were counted, and bacterial burden per cm2 calculated. Results Of 160 objects included in the study, 36 (23%) showed a CFU-count of zero both before and after HPDM use. A decrease from a median of 0.14 CFU/cm2 (range 0.00-125.00/cm2) to a median of 0.00 CFU/cm2 (range 0.00-4.00/cm2) (P less then .001) was observed. The bacterial burden was reduced by more than 90% in 45% (95% CI 37-53) of objects. No pathogenic bacteria were identified. Discussion HPDM reduced bacterial burden on noncritical medical items. Since cleanliness of the included "ready to use" objects was high and no pathogens were found before nebulization, the HPDM device did not increase patient safety in this setting. Conclusion HPDM nebulization can be a useful nonmanual adjunctive disinfection method in high-risk settings.When two objects are presented in alternation at two locations, they are seen as a single object moving from one location to the other. This apparent motion (AM) percept is experienced for objects located at short and also at long distances. However, curr
