Article Synopsis
- A systematic review and meta-analysis was conducted to assess the effectiveness of water, sanitation, and hygiene (WASH) interventions on childhood diarrhoea in low- and middle-income countries, focusing on high-level service interventions.
- The review analyzed data from 124 studies, which included over 200,000 children across different WASH intervention categories, such as water treatment, sanitation improvements, and hygiene practices.
- The findings indicated that treated water, such as through filtration, solar treatment, and chlorination, significantly reduced the risk of diarrhoea by up to 50% compared to untreated water sources.

Article Synopsis
- Low-income countries face higher risks of COVID-19 due to limited healthcare capacity and lack of access to effective preventive measures like handwashing.
- Global data shows that, as of 2019, around 2 billion people (about 26.1% of the global population) did not have access to handwashing facilities with soap and water, with over half of the populations in sub-Saharan Africa and Oceania lacking this essential resource.
- Urgent improvements in access to handwashing and the consideration of disparities in hygiene access are critical for predicting and managing COVID-19 risks in low-income regions.
