Did the pandemic lead to behaviour changes in WASH practices? This research in rural Odisha reveals a change in handwashing practice due to COVID-19. People engaged in handwashing more frequently, followed a more thorough washing method, and/or used soap. These improved practices remained in place a few months after the pandemic began, and became a new consistent practice, suggesting habit formation. The results highlight the importance of ensuring communities have adequate WASH infrastructure to enable the practice of safe behaviors and strengthen resilience during a large-scale health crisis.
