In the PAASIM study (Pesquisa Sobre o Acesso à Água e a Saúde Infantil em Moçambique - Research on Access to Water and Children's Health in Mozambique), we are testing if and how improvements in water supply in urban areas of Mozambique reduce or delay enteric pathogen infection, alter gut microbiome composition, and affect enteric dysfunction and  other health outcomes in infants.  Results will contribute novel findings to inform policy on how to optimize investments to improve child health in low-income, urban settings. This work is co-led by Karen Levy at Emory and is funded by an R01 grant from NIAID.  Other collaborators include Joe Brown and Kostas Konstantinidis at Georgia Tech,  Josh Garn at UNR, Tom Clasen, Lance Waller, and Colleen Kraft at Emory, and Mozambican water and health agencies.
