Climate change and globalization are two factors leading to disease-carrying viruses finding their way to more places around the world. Scientists say more intensive environmental surveillance could help halt the spread of viruses. One way Fulton Schools Professor Rolf Halden wants to do that is through a global wastewater-monitoring initiative he has launched. He hopes to see more work related to the research he is leading in ASU’s Center for Environmental Health Engineering. Halden and his team are developing new and improved methods of monitoring and analyzing wastewater to reveal information about public health conditions. Such efforts could help pinpoint where viruses are moving.
