Unpacking the Enabling Factors for Hand, Cord and Birth-Surface Hygiene in Zanzibar Maternity Units. Health Policy and Planning, June 2017. A study of maternity units in Zanzibar, finds a lack of essential infection prevention practices like knowledge and training, and infrastructure requirements to enable clean hands, such as constant running water.
Understanding the Challenges of Improving Sanitation and Hygiene Outcomes in a Community Based Intervention: A Cross-Sectional Study in Rural Tanzania. International Journal of Environmental Research and Public Health, June 2017. In rural Tanzania, researchers studied how factors such as water storage and usage, safe excreta disposal, and other hygiene practices—not just the availability of water alone—are critical for interventions to prevent the spread of waterborne diseases.
A Method to Test the Efficacy of Handwashing for the Removal of Emerging Infectious Pathogens. Journal of Visualized Experiments, June 2017. The authors of this paper describe a laboratory method to assess the efficacy of handwashing for removing micro-organisms from hands and their persistence in rinse water. The method fills research gaps on handwashing efficacy.
Provision Versus Promotion to Develop a Handwashing Station: The Effect on Desired Handwashing Behavior. BMC Public Health, May 2017. Diarrhea in children tends to increases when they start eating solid foods, possibly due to poor hand hygiene by the caregiver during food preparation. This three-month pilot intervention helped households set up handwashing stations and tested the feasibility of integrating this intervention with a child feeding program.
Behavioral Antecedents for Handwashing in a Low-Income Urban Setting in Bangladesh: An Exploratory Study. BMC Public Health, May 2017. This study states that the rate of handwashing with soap is influenced by a broader range of factors, many unrelated to fecal contamination, that indicate to people when and where to wash their hands. This study attempts to create a comprehensive list of these factors.
Does Targeting Children with Hygiene Promotion Messages Work? The Effect of Handwashing Promotion Targeted at Children, on Diarrhoea, Soil-Transmitted Helminth Infections and Behaviour Change.Tropical Medicine International Health, May 2017. This literature review of handwashing interventions targeting children found only limited research and a lack of sufficient evidence to determine the most effective means to increase handwashing with soap among children.
Impact of an Intensive Perinatal Handwashing Promotion Intervention on Maternal Handwashing Behavior in the Neonatal Period. Hindawi BioMed Research International, April 2017. Researchers examined the impact of intensive handwashing promotion on handwashing behavior of mothers of neonates. They found that intensive promotion resulted in increased availability of soap and water at handwashing places, but only a modest increase in maternal handwashing with soap.
Hand Hygiene Intervention Strategies to Reduce Diarrhoea and Respiratory Infections among Schoolchildren in Developing Countries: A Systematic Review. International Journal Environmental Research and Public Health, April 2017. The objective of this review was to identify hand hygiene intervention strategies to reduce infectious diseases such as diarrhea and respiratory tract infections among schoolchildren. The review adds to the existing evidence that multi-level handwashing interventions can reduce the incidence of diarrhea, respiratory infections, and school absenteeism.
Handwashing and Ebola Virus Disease Outbreaks: A Randomized Comparison of Soap, Hand Sanitizer, and 0.05% Chlorine Solutions. PLoS One, February 2017. The authors in this study evaluated six handwashing protocols for efficacy of handwashing on nonpathogenic model organisms and persistence of organisms in rinse water. It was found that chlorine-based methods may offer a benefit of reducing persistence in rinse water.
Contextual and Psychosocial Determinants of Effective Handwashing Technique: Recommendations for Interventions from a Case Study in Harare, Zimbabwe. American Journal of Tropical Medicine and Hygiene, February 2017. This case study identifies behavioral determinants of effective handwashing, which include knowledge of how to wash hands effectively, availability of a handwashing station with functioning water tap, and self-reported frequency of handwashing.
Nonrandomized Trial of Feasibility and Acceptability of Strategies for Promotion of Soapy Water as a Handwashing Agent in Rural Bangladesh. American Journal of Tropical Medicine and Hygiene, February 2017. This trial finds that soapy water may increase habitual handwashing by addressing barriers of cost and availability of handwashing agents near water sources. It recommends further research on ways to scale-up soapy water as a handwashing agent to study health impact.
Exploring the Link Between Handwashing Proxy Measures and Child Diarrhea in 25 Countries in Sub-Saharan Africa: A Cross-Sectional Study. Journal of Water, Sanitation and Hygiene for Development, March 2017. This study examined the link between handwashing measures and child diarrhea, finding that the availability of handwashing resources is important for preventing child diarrhea, as are handwashing promotion programs, which should be tailored to the unique context of each country.
