Editorial: Limited services? The role of shared sanitation in the 2030 Agenda for Sustainable Development. JWASH for Dev. In press. There is no reason to stop investing in shared sanitation. ‘Safely managed’ represents a standard countries should aspire to. However, the 2030 Agenda and the human rights recognise the need for intermediate steps and for reducing inequalities. This calls for prioritising investments in high-quality shared toilets in dense informal settlements where it is the only viable option (short of rehousing) for improving sanitation services.

Assessment of the Acceptability and Feasibility of Child Potties for Safe Child Feces Disposal in Rural Bangladesh. AJTMH, June 2017. Residents of this rural Bangladeshi community accepted the child potties and caregivers found them to be a feasible means of managing child feces. The color, shape, design, and size of the potty influenced its acceptability and use. These residents reported that regular use of the potty improved the household’s physical environment and caregiver and child personal hygiene.

Associations between Household Latrines and the Prevalence of Diarrhea in Idiofa, Democratic Republic of the Congo: A Cross-Sectional Study. AJTMH, June 2017. We have observed the profound protective effect of latrines with a superstructure. This study demonstrates that latrines are associated with significant improvements in health even when they do not fully meet the conditions of improved latrines.

More Poop, More Precision: Improving Epidemiologic Surveillance of Soil-Transmitted Helminths with Multiple Fecal Sampling using the Kato–Katz Technique. AJTMH, July 2017. Our findings show that analysis of an additional fecal sample led to increases of 23%, 26%, and 100% for Ascaris lumbricoides, Trichuris trichiura, and hookworm prevalence, respectively.

Integrated surveillance of antimicrobial resistance in foodborne bacteria: Application of a One Health approach. WHO, 2017. This guidance document is to assist countries and other stakeholders in the establishment and development of programmes of integrated surveillance of antimicrobial resistance in the foodborne bacteria (i.e., bacteria commonly transmitted by food) by taking a One Health approach.

Improving water, sanitation and hygiene in health-care facilities, Liberia. WHO Bulletin, July 2017. National leadership was important to identify a vision and to create an enabling environment for changing the perception of water, sanitation and hygiene in health-care provision.

Exposure–response relationship of neighbourhood sanitation and children’s diarrhea. Trop Med Intl Health, July 2017. Our findings suggest that neighbourhood sanitation plays a key role in reducing diarrhoeal diseases and that increase in sanitation coverage may only have minimal impact on diarrhoeal illness, unless sufficiently high coverage is achieved.

Behaviour change intervention to improve shared toilet maintenance and cleanliness in urban slums of Dhaka: a cluster-randomised controlled trial. TMIH, early view. In one of few efforts to promote shared toilet cleanliness, intervention compounds were significantly more likely to have cleaner toilets after six months. Future research might explore how residents can self-finance toilet maintenance, or employ mass media to reduce per-capita costs of behaviour change.

If I do not have enough water, then how could I bring additional water for toilet cleaning?! Addressing water scarcity to promote hygienic use of shared toilets in Dhaka, Bangladesh. TMIH, June 27, 2017. Our pilot demonstrates the potential efficacy of low-cost water storage and behavior change communications to improve maintenance of and user satisfaction with shared toilets in urban slum settings.
