RESUMO
The new Lancet Commission on water, sanitation, and hygiene (WASH) hopes to reimagine and guide global WASH efforts. This comes at a time when unequal living conditions and global disparities in response and recovery have been highlighted by the COVID-19 pandemic and recent large impact trials have delivered mostly disappointing results suggesting the need for radically more effective interventions to improve global public health. We find ourselves at an inflection point in global WASH with an opportunity to build new approaches with potentially more equitable, cost-effective, and scalable solutions. Mobile health (mHealth) technology is an important and innovative tool for WASH advances. Yet, the use of mHealth has not been equally distributed in terms of its benefits nor is its impact guaranteed. In resource-constrained settings, where technology can increase inequalities, special attention should be paid to structural and systemic hierarchies during the development of mHealth programs along with the acknowledgment and understanding how these systems can reinforce the systematic exclusion of those most vulnerable. The WASH sector needs to adapt to a future that is innovative and inclusive with a commitment to rethinking the resources needed to enhance scope and impact. We highlight urban sanitation in Brazil as a case study to demonstrate that mHealth can support and enhance publicly funded infrastructure and to help reimagine WASH for postpandemic and beyond.
