Now a study out Oct. 22, 2024, in Environmental Research Letters by an international team of investigators led by senior author from University of Maryland’s School of Public Health (UMD SPH) Amir Sapkota, offers a way to predict the risk of such deadly outbreaks using AI modeling, giving public health systems weeks or even months to prepare and to save lives. “Increases in extreme weather events related to climate change will only continue in the foreseeable future. We must adapt as a society,” said Sapkota, who is chair of the SPH Department of Epidemiology and Biostatistics. “The early warning systems outlined in this research are a step in that direction to enhance community resilience to the health threats posed by climate change.” The multidisciplinary team, working across several institutions, relied on temperature, precipitation, previous disease rates, El Niño climate patterns as well as other geographic and environmental factors in three countries - Nepal, Taiwan, and Vietnam - between 2000 and 2019. Using this data, the researchers trained AI-based models that can predict area-level disease burden with weeks to months ahead of time. “Knowing expected disease burden weeks to months ahead of time provides public health practitioners crucial time to prepare. This way they are better prepared to respond, when the time comes” Sapkota said.While the study focused on Nepal, Vietnam, and Taiwan, “our findings are quite applicable to other parts of the world as well, particularly areas where communities lack access to municipal drinking water and functioning sanitation systems,” said lead author of the study Raul Curz-Cano, Associate Professor at Indiana University School of Public Health in Bloomington. Sapkota says AI’s ability to work with huge data sets means that this study is an early step among many he anticipates will result in increasingly accurate predictive models for early warning systems. He hopes this will allow public health systems to prepare communities to protect themselves from a heightened risk of diarrheal outbreaks. The team responsible for the research came from a wide variety of fields, including atmospheric and oceanic science, community health research, water resources engineering and beyond. The research team was comprised of authors from UMD – including its Department of Epidemiology and Biostatistics and Department of Atmospheric and Oceanic Science – and from Indiana University School of Public Health in Bloomington, the Nepal Health Research Council, the Hue University of Medicine and Pharmacy in Vietnam, Lund University in Sweden, and Chung Yuan Christian University in Taiwan.

UMD researcher trains AI to predict diarrheal outbreaks related to climate change

Climate change-related extreme weather, such as massive flooding and prolonged drought, often result in dangerous outbreaks of diarrheal diseases particularly in less developed countries, where diarrheal diseases is the third leading cause of death among young children. Now a study out Oct. 22, 2024, in Environmental Research Letters by an international team of investigators led by senior author from University of Maryland’s School of Public Health (UMD SPH) Amir Sapkota, offers a way to predict the risk of such deadly outbreaks using AI modeling, giving public health systems weeks or even months to prepare and to save lives.
