Animal Feces Exposure

A number of human pathogens can be found in animal feces, yet the feces from these animals pose a currently unquantified risk to human health.  It is possible that WASH interventions may fail due to persistent exposure to fecal pathogens of animal (zoonotic) origin.  In close collaboration with Karen Levy's research group, we are working to explore the potential human health risks of exposure to animal feces in low-income settings. This work is funded by the Bill & Melinda Gates Foundation.
