Surface contamination with any bacteria did not vary by frequency of cleaning or frequency of illness (p>.05). Copyright: © 2013 Miko et al. Two recent studies by Roberts et al. Little is known about the prevalence or significance of environmental contamination in the university setting. No, Is the Subject Area "Infectious diseases" applicable to this article? Whether such contamination has clinically meaningful effects on infection risk is unanswered at present. As such, this population may be well suited for hygiene interventions with sustained impact over adult life. A Chartered Chemist and … Liquid hand soap was the most common product used for hand hygiene (n = 418, 83.4%) with a minority regularly using hand sanitizer (n = 179, 35.7%). This research was approved by the Columbia University Medical Center Institutional Review Board (CUMC IRB) and conducted with the assistance of Student Health Services, Housing Services, and Dining Services. Contamination of certain surfaces was common, with at least one third of all bookshelves, desks, refrigerator handles, toilet handles, and bathroom door handles positive for >10 CFU of bacteria per 4 cm2 area. While the vast majority of study participants (n = 461, 92%) believed that hand washing was important for infection prevention, there was a large amount of variation in reported personal hygiene practices. 65 students (13%) missed class over the previous month due to these complaints; 56 (11.2%) sought medical care. The aim of personal hygiene is to promote standards of personal cleanliness, within the setting of the condition where people live. In 2018 IFH published a consensus report which sets out why hygiene in home and everyday life is such an important part of public health, and what needs to be done to change hygiene understanding and hygiene behaviour as a means to tackle some of the key present day health issues such as reducing antibiotic resistance and reducing pressure on our health systems. Several objects showed a high burden of bacterial contamination, with over 90% of computer keyboards positive when cultured late in the day. As this is the first study of dormitory residents to evaluate the relationship between environmental colonization, reported hygiene habits, and reported health status, it is not possible to assess for congruence with other studies. Environmental Hygiene, Environmental Services, Clinical Interventions By Kelly M. Pyrek Numerous studies have demonstrated that contaminated environmental surfaces in healthcare facilities can contribute to the transmission of infectious pathogens and that the cleaning and disinfection of these high-touch surfaces has been suboptimal. Hygiene at household level and Hygiene at the community level. The presence or absence of clinical infection prior to microbiological sampling may have altered endogenous bacterial shedding into the environment or cleaning habits. The environmental sampling protocol was subsequently explained to study participants. Regular face- and hair-washing, application of deodorant, and the use of soap and feminine hygiene products are other important aspects of personal hygiene to consider. Oral hygiene---or the process of caring for the teeth and gums---is vital for optimal health and attractiveness. Benjamin A. Miko, Coagulase-positive Staphylococcus was detected in three participants' rooms (5%) and coliforms were present in six students' rooms (10%). examined S. aureus surface contamination at the University of Washington (specifically, the dental school clinic, general university campus, student homes, and surrounding community) , . These conditions include unsanitary water supplies, waste disposal systems, food sources, and temporary or permanent housing structures. Several survey respondents reported symptoms of an infectious disease over the preceding month. e81460. found that a multifactorial hygiene campaign including decontamination of classroom surfaces reduced the risk of gastroenteritis among a cohort of school children . Analyzed the data: BAM BC KH. The purpose of this study was to characterize the personal and environmental hygiene habits of college students, define the determinants of hygiene in this population, and assess the relationship between reported hygiene behaviors, environmental contamination, and health status. While every effort was made to culture surfaces in a timely manner, some subjects were cultured up to two weeks after survey completion, further impairing our comparison of questionnaire data with microbiological findings. The most commonly noted health conditions were asthma (n = 45, 9%) and seasonal allergies (n = 55, 11%). about 80 % of illnesses are caused due to poor environmental and personal hygiene. In addition, sample size may have limited our ability to identify statistically significant associations. Type 1 diabetes mellitus (n = 2, 0.4%) and cardiovascular disease (n = 1, 0.2%) were rarely noted. A total of 501 students completed the study survey. The >10 CFUs cut point was chosen for this dichotomous analysis because of its clinical relevance as an inoculation dose for particular pathogens (e.g., S. aureus) and its statistical discrimination (>10 CFUs represented the upper quartile of our environmental specimens). Our Environmental Hygiene Group is led by Registered Occupational Hygienist Broderick Mossman and staffed by a team of experts in the field. While the toxin is being removed, the hygienists might also hold forums explaining the symptoms and treatments of MRSA to anyone who is affected by it. https://doi.org/10.1371/journal.pone.0081460.t002. The instrument retrospectively assessed specific aspects of health and hygiene over the preceding 30 days. Microbiological samples were collected using pre-moistened rayon-tipped culturette swabs (Becton Dickinson, Franklin Lakes, NJ). Similar to military barracks, college dormitories house large numbers of young adults in close proximity, often with variable infection control practices. Participants included in our previous study were not included in this analysis. Maintain personal and environmental hygiene to limit monsoon woes. Department of Epidemiology, Mailman School of Public Health, Columbia University, New York, New York, United States of America, Affiliation Importance Of Personal And Environmental Hygiene When working in a healthcare setting, regardless of an individual’s role, every team member is responsible for maintaining not only exceptional personal hygiene but also the cleanliness of their surroundings. Study subjects noted diverse determinants of their hygiene habits. While all individuals would likely benefit from improved hygiene practices, certain populations may be particularly impacted by directed hygiene interventions. Dr Charu Goel Sachdeva. Noel Hendrickson/Blend Images/Getty Images. Most of these practices are done on a daily basis, because of the tendency of our bodies to get unclean easily. Although a growing literature has clarified the determinants and effects of particular hygiene behaviors, many practices remain incompletely understood . The aims of this study were to (1) describe the knowledge, practices, and beliefs about personal and environmental hygiene held by college students living in dormitories; (2) examine and quantify the microbial flora present on surfaces in students' dormitory rooms and bathrooms; (3) determine whether there is an association between reported knowledge, practices, and beliefs about personal and home hygiene and frequency of illness; and (4) determine whether there is an association between microbial flora found in dormitory environments and frequency of illness. Further research into environmental reservoirs of infectious diseases may delineate whether surface decontamination is an effective target of hygiene interventions in this population. While the majority of subjects reported that their living space was cleaned on a weekly basis (n = 314, 62.7%), a subset reported cleaning on a daily basis (n = 53, 10.6%) or monthly basis (n = 61, 12.2%). Two of these students reported cleaning daily, three weekly, two monthly, and one never. Those wishing to volunteer for this portion of the study were asked to provide contact information to schedule the study visit to their living space. Common complaints included cough (n = 272, 54.3%), runny nose (n = 357, 71.3%), upset stomach (n = 247, 49.3%), vomiting (n = 83, 16.6%), diarrhea (n = 97, 19.4%), and fever (n = 65, 13%).

PLOS ONE promises fair, rigorous peer review, Lower classmen were significantly more likely than upper classmen to report washing their hands after using the toilet. Environmental hygienists work with local and federal authorities to uncover potential sources of contamination within these systems. Environmental sampling visits occurred within two weeks of survey completion. It is possible that in certain populations at elevated risk for infection – including college dormitory residents – environmental contamination may be of increased importance, thereby mimicking healthcare populations rather than lower risk community residents. Division of Infectious Diseases, College of Physicians and Surgeons, Columbia University, New York, New York, United States of America, Despite this hypothesis, our study failed to show an association between contamination of dormitory surfaces and (1) dormitory style, (2) reported household hygiene, and (3) reported illness. Environmental hygiene can be looked at from two aspects, viz. Signs of poor health keep many people at distance to avoid getting a disease. Disposable dishes or cups were cleaned frequently (daily n = 280, 55.9%; weekly n = 114, 22.8%). While our study demonstrated significant bacterial surface contamination, coagulase-positive Staphylococcus was infrequently found. Bacterial contamination of specific surfaces was variable, ranging from no growth to CFUs too numerous to count. All participants were given an information sheet describing the study and provided verbal informed consent. Provides a list of industrial hygiene consultants and their fields of activity (control of lead and asbestos in the workplace, ionizing radiation, etc.) Despite these limitations, our study provides new insight into the relationship between hygiene and health in the college dormitory setting. Environmental contamination with coagulase-positive Staphylococcus (e.g., S. aureus) and coliforms was assessed using direct inoculation onto selective agar (mannitol salt and MacConkey, respectively). What Are the Steps of Presidential Impeachment? This does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials, as detailed online in the guide for authors. Recruitment procedures are detailed in our previous research in this population, and briefly described below . Several studies have demonstrated that improved hygiene behaviors – particularly hand washing – are effective in reducing the incidence of certain infections such as viral upper respiratory infection and gastroenteritis , . Wrote the paper: BAM. For the survey portion of our study, pre-enrollment sample size analysis demonstrated sufficient power to detect clinically meaningful differences between comparison groups (95% power for odds ratios of 2 or greater for total sample size of 500). The role of the residential environment has been a focus of particularly controversial debate in recent years. Shared living spaces, close physical contact, and variable hygiene likely contribute to the enhanced transmission of infectious agents in the dormitory setting . You … Presents the types of qualification examinations that are offered by the Industrial Hygiene Faculty to classify members in the existing categories. It is important for maintaining both physical and mental health.

While several studies have documented the importance of hand washing in the university setting, the added role of environmental hygiene remains poorly understood. Reported hand hygiene practices varied greatly among study participants. https://doi.org/10.1371/journal.pone.0081460, Editor: Holger Rohde, Universitätsklinikum Hamburg-Eppendorf, Germany, Received: August 10, 2012; Accepted: October 23, 2013; Published: November 27, 2013.
