Worldwide more deaths occur due to conditions that can be ameliorated by behavior change. Changing health behaviors using models popularized in non-western countries has not proven particularly successful. The purpose of this study was to test variables elicited during qualitative interviews and cultural conversations to develop a model of health behavior change from the ground up in Vietnam. Village leaders and women representatives from the Women's Committee were trained as health advocates to facilitate changes in health practices that led to parasitic and infectious diseases...

INTRODUCTION: Reproductive health of adolescent girls is crucial as it determines the health of future generations. School girls when experiencing menarche find themselves in a setting without water, toilets or a supportive female teacher to explain the changes happening in their body. An important concern for adolescent girls is to have adequate, correct knowledge along with facilities and the cultural environment to manage menstruation hygienically and with dignity. Hence, the present study was done to assess knowledge and practices about menstruation in adolescent school girls of an urban slum...

BACKGROUND: In resource-limited settings where laboratory capacity is limited and response strategy is non-specific, delayed or inappropriate intervention against outbreaks of Norovirus (NoV) are common. Here we report interventions of two norovirus outbreaks, which highlight the importance of evidence-based modeling and assessment to identify infection sources and formulate effective response strategies. METHODS: Spatiotemporal scanning, mathematical and random walk modeling predicted the modes of transmission in the two incidents, which were supported by laboratory results and intervention outcomes...

BACKGROUND: Previous studies have shown that women have higher concentrations of the endocrine disruptor bisphenol A (BPA), but an intervention to reduce BPA is lacking in women. To test the hypothesis that an intervention to reduce BPA would decrease urinary BPA concentrations over 3 weeks, 24 women (mean ± standard deviation [SD]; 22.1 ± 2.8 kg/m(2) body mass index, 20.9 ± 1.5 years) were randomly assigned to an intervention or control. MATERIALS AND METHODS: The intervention included weekly face-to-face meetings to reduce BPA exposures from food, cosmetics, and other packaged products...

Household members of cholera patients are at a 100 times higher risk of cholera infections than the general population because of shared contaminated drinking water sources and secondary transmission through poor household hygiene practices. In this study, we investigated the bactericidal concentration of free chlorine required to inactivate Vibrio cholerae in household drinking water in Dhaka city. In laboratory experiments, we found that the concentrations of free chlorine required to inactivate 10(5) colony-forming units (CFU)/mL of V...

Oral rinses containing chemotherapeutic agents, such as cetylpyridinium chloride (CPC), can alleviate plaque-induced gingival infections, but how oral microbiota respond to these treatments in human population remains poorly understood. Via a double-blinded, randomised controlled trial of 91 subjects, the impact of CPC-containing oral rinses on supragingival plaque was investigated in experimental gingivitis, where the subjects, after a 21-day period of dental prophylaxis to achieve healthy gingivae, received either CPC rinses or water for 21 days...

Acanthamoeba, a free-living amoeba, is widely distributed in the environment, water sources, soil, dust, and air. It can cause keratitis in contact lens wearers with poor hygiene and also fatal granulomatous amebic encephalitis (GAE) in immunocompromised hosts. The aim of this study was to gain some insights into the distribution and genotypes of the potentially pathogenic species of Acanthamoeba present in water sources in north of Iran. Total 43 Acanthamoeba species were isolated from 77 water samples taken from different water sources within the Mazandaran province in Northern Iran (Sari city and suburbs)...

Legionellae are waterborne bacteria which are capable of causing potentially fatal Legionnaires' disease (LD), as well as Pontiac Fever. Public concern about Legionella exploded following the 1976 outbreak at the American Legion conference in Philadelphia, where 221 attendees contracted pneumonia and 34 died. Since that time, a variety of different control methods and strategies have been developed and implemented in an effort to eradicate Legionella from building water systems. Despite these efforts, the incidence of LD has been steadily increasing in the U...

There is little evidence on prevalence or risk factors for soil transmitted helminth (STH) infections in Timor-Leste. This study describes the epidemiology, water, sanitation and hygiene (WASH), and socioeconomic risk factors of STH and intestinal protozoa among communities in Manufahi District, Timor-Leste. As part of a cluster randomised controlled trial (RCT), a baseline cross-sectional survey was conducted across 18 villages, with data from six additional villages. Stool samples were assessed for STH and protozoal infections using quantitative PCR (qPCR) and questionnaires administered to collect WASH and socioeconomic data...

This study aimed to investigate the effects of alcohol-based hand hygiene solution (ABHS) use by care providers on point-of-care alcohol breath analyzer interpretation under different clinically relevant conditions. Among each test condition (foam vehicle with immediate testing, gel vehicle with immediate testing, allowing hands to dry after the use of ABHS, and donning gloves after the use of ABHS), alcohol was detected in breath at 1 minute after use of ABHS. Because the use of ABHS by individuals administering breath alcohol detection may result in false-positive detection of alcohol, staff using these devices should consider traditional hand hygiene with soap and water...

India's Kumbh Mela remains the world's largest and longest mass gathering. The 2013 event, where participants undertook a ritual bath, hosted over 70 million Hindu pilgrims during 55 days on a 1936 hectare flood plain at the confluence of the Yamuna and Ganga Rivers. On the holiest bathing days, the population surged. Unlike other religious, cultural, and sports mass gatherings, the Kumbh Mela's administration cannot estimate or limit the participant number. The event created serious and uncommon public health challenges: initiating crowd safety measures where population density and mobility directly contact flowing bodies of water; providing water, sanitation, and hygiene to a population that frequently defecates in the open; and establishing disease surveillance and resource use measures within a temporary health delivery system...

Intestinal parasites are important enteric pathogens. Poverty, low quality of food and water supply and poor sanitation systems are the important factors associated with intestinal parasitic infections. These kinds of infections can be a good index for hygienic and sanitation status of the society. This study aimed to determine the prevalence of intestinal parasitic infections among humans referred to Dr. Sharifi Clinical Laboratory, Isfahan, Iran, 2014. In this cross sectional study, 652 fecal samples (286 males and 366 females) from humans who had stool examination test from January to August 2014 were chosen...

Herd immunity arises when a communicable disease is less able to propagate because a substantial portion of the population is immune. Nonimmunizing interventions, such as insecticide-treated bednets and deworming drugs, have shown similar herd-protective effects. Less is known about the herd protection from drinking water, sanitation, and hand hygiene (WASH) interventions. We first constructed a transmission model to illustrate mechanisms through which different WASH interventions may provide herd protection...
