Health care-associated infections (HAI) remain a major cause of patient morbidity and mortality. Although the main source of nosocomial pathogens is likely the patient’s endogenous flora, an estimated 20% to 40% of HAI have been attributed to cross infection via the hands of health care …
In view of the evidence that transmission of many healthcare acquired pathogens (HAPs) is related to contamination of near-patient surfaces and equipment, all hospitals are encouraged to develop programs to optimize the thoroughness of high touch surface cleaning as part of terminal room cleaning at …
Abstract Objective To determine the effectiveness of a UV-C-emitting device to eliminate clinically important nosocomial pathogens in a contaminated hospital room. Methods This study was carried out in a standard but empty hospital room (phase 1) and in a room previously occupied by …
Abstract Carpets are both sinks and sources for exposure to chemicals, allergens, and microbes and consequently influence health, including asthma, allergies, and infectious diseases. Asthmatics, children, and the immune-compromised are particularly vulnerable to health risks resulting from exposure to carpet contaminants. To address this risk, …
Abstract Increasing numbers of hospital-acquired infections have generated much attention over the last decade. The public has linked the so-called ‘superbugs’ with their experience of dirty hospitals but the precise role of environmental cleaning in the control of these organisms remains unknown. Until cleaning …
Abstract Background High-quality vacuum cleaners and vacuum cleaner bags are often recommended to allergic patients as a means of reducing indoor allergen exposure. A number of vacuum cleaners on the market today claim to capture 99.9% of particles 0.3 micron or larger entering the vacuum …
Abstract Recent studies using direct covert observation or a fluorescent targeting method have consistently confirmed that most near patient surfaces are not being cleaned in accordance with existing hospital policies while other studies have confirmed that patients admitted to rooms previously occupied by patients …
Abstract Use of Acid Water to Clean Plastic Cutting Boards One milliliter of culture containing a five-strain mixture of Escherichia coli O157:H7 (approximately 10(10) CFU) was inoculated on a 100-cm2 area marked on unscarred cutting boards. Following inoculation, the boards were air-dried …
Abstract Assessment of the risks posed by severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV) on surfaces requires data on survival of this virus on environmental surfaces and on how survival is affected by environmental variables, such as air temperature (AT) and relative humidity (RH). …
The swabs used for sampling surfaces for microbial contamination are examples of devices that are simple in design and construction, but are difficult to use without discipline and training. This article discusses why this is so. At present, swabs are widely used in the cleaning …
