Objective: Promoting handwashing with soap to mothers of young children can significantly reduce diarrhoea and pneumonia morbidity among children, but studies that measured long-term behaviour after interventions rarely found improvements in handwashing habits. Expecting mothers may experience emotional and social changes that create a unique environment that may encourage adoption of improved handwashing habits. The objective of this study was to determine whether exposure to an intensive handwashing intervention in the perinatal period (perinatal arm) was associated with improved maternal handwashing behaviour vs. exposure to the same intervention after the end of the perinatal period (post-neonatal arm).
Methods: We identified primiparous women previously enrolled a randomised controlled handwashing intervention trial (November 2010-December 2011) and observed handwashing behaviours at the home 1-14 months after completion of the RCT (January-May 2012). We observed maternal handwashing and estimated the prevalence ratio (PR) of maternal handwashing using log-binomial regression.
Results: We enrolled 107 mothers in the perinatal arm and 105 mothers in the post-neonatal arm. Handwashing with soap at recommended times was low overall (4.6%) and comparable between arms (PR = 0.9, 95% CI 0.5, 1.5).
Conclusions: This handwashing intervention was unable to develop and establish improved handwashing practices in primiparous women in rural Bangladesh. While pregnancy may present an opportunity and motivation to do so, further studies should assess whether social, individual and environmental influences overcome this motivation and prevent handwashing with soap among new mothers.

Background: To reduce the spread and transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), schools implemented a series of non-pharmacological interventions such as handwashing stations and cleaning protocols. A baseline assessment of the available interventions and readiness scores for SARS-CoV-2 prevention was conducted in primary schools in Maputo City, Mozambique.

Whilst improving hygiene and sanitation behaviours is key to cost-effective and sustainable water, sanitation and hygiene interventions, measuring behaviour change remains a challenge. This study assessed the validity and reliability of pictorial 24-h recall (P24 hR), a novel method using unprompted recall of past activities through pictures, compared to structured observation for measuring handwashing with soap (HWWS) and safe child faeces disposal in rural Malawi. Data were collected from 88 individuals across 74 households in Chiradzulu district using both methods over a two-day period, with the recall period of the P24 hR corresponding to the period of structured observation completed the previous day.

Introduction: Behaviour change interventions have the potential to improve sanitation and hygiene practices in urban settings. However, evidence on which behaviour change interventions have successfully improved sanitation and hygiene practices in urban settings is unclear.
Methods: We performed electronic searches across five databases and one grey literature database to identify relevant studies published between January 1, 1990 and November 20, 2023 in English.

Background: Routine epidemiological data are essential for monitoring the effectiveness of preventive chemotherapy (PC), optimizing resource allocation, and addressing the evolving needs in the elimination of soil-transmitted helminthiasis (STH). This study assesses the prevalence, intensity, and associated risk factors of STH following five rounds of albendazole-based PC in three implementation units (IUs) in Ondo State, Nigeria.
Methodology: Fresh stool samples were collected from 2,093 children aged 5-14 years across 45 systematically selected schools in three IUs: Ese-Odo, Irele, and Ile-Oluji.
