“…As a result, environmental cleaning has been emphasized as one of the important parts of an effective infection-control strategy. The rationale for using sodium hypochlorite for environmental cleaning in our study was based on the fact that (1) several studies have used 1:100 sodium hypochlorite to control MDR A. baumannii outbreaks successfully [29][30][31][32][33], (2) existing data suggested that cleaning floors with either detergent or disinfectant did not affect nosocomial infection rates [34], and (3) a study reported that a quaternary ammonium compound was inadequate for disinfecting bathrooms and toilets [29]. In contrast, studies have suggested that hypochlorite-based environmental cleaning can be associated with a reduced incidence of hospital-acquired Clostridium difficile infection [35][36][37].…”

“…Several studies suggest that the environment serves as a reservoir of infectious FLP for infection of humans, animals and plants [8,15,44]. Whereas other works conclude that the contaminated environment is only a minor factor within the complicated nature of infectious diseases [2,16,17,29,40]. To reflect these diverse opinions, we hypothesize three scenarios where the environment acts as a (I) Transition, (II) Transition-Reservoir and (III) Reservoir.…”

The basic reproduction number R 0 for a compartmental disease model is often calculated by the next generation matrix (NGM) approach. When the interactions within and between disease compartments are interpreted differently, the NGM approach may lead to different R 0 expressions. This is demonstrated by considering a susceptible-infectious-recovered-susceptible model with free-living pathogen (FLP) growing in the environment. Although the environment could play different roles in the disease transmission process, leading to different R 0 expressions, there is a unique type reproduction number when control strategies are applied to the host population. All R 0 expressions agree on the threshold value 1 and preserve their order of magnitude. However, using data for salmonellosis and cholera, it is shown that the estimated R 0 values are substantially different. This study highlights the utility and limitations of reproduction numbers to accurately quantify the effects of control strategies for infections with FLPs growing in the environment.

“…Most studies have shown that similar results in lowering microbial growth can be achieved by using detergents or disinfectants, but neither appears to affect the rates of HAI (Daschner et al 1980;Danforth et al 1987). Some studies advocate that the use of a disinfectant in floor cleaning is reasonable practice (Rutala & Weber 2001;Wilcox et al 2003).…”

Hospital hygiene may be associated with hospital-acquired infection. This study evaluated four hospital cleaning methods: 'mop and vacuum', 'spray clean' and 'wet scrub' for floors, and one steam cleaning method for curtains. A standardised microbiological screening method was used to sample the environment before and after cleaning in order to quantify total viable counts as well as identify specific organisms. The results showed that all floor cleaning methods reduced the overall microbial load, although high counts and bacterial pathogens occasionally persisted despite cleaning. Spray cleaning gave marginally better results than traditional mopping and vacuuming. Wet scrubbing significantly reduced levels of coagulase-positive staphylococci (p = 0.03), which, in combination with routine methods, produced an effect that persisted for at least a week. Steam cleaning of curtains also reduced microbial counts (p = 0.08), but had little effect on Staphylococcus aureus and other potential pathogens. These results might help managers assess the costs of different cleaning methods against potential infection control benefits in a hospital.
