A team led by Tufts researchers has found that healthcare costs are rising for infections linked to bacteria in water supply systems. The costs may now exceed $2 billion for 80,000 cases per year, and antibiotic resistance may be contributing to the trend.
“Premise plumbing pathogens can be found in drinking water, showers, hot tubs, medical instruments, kitchens, swimming pools—almost any premise where people use public water. The observed upward trend in associated infections is likely to continue, and aging water distribution systems might soon be an additional reservoir of costly multidrug resistance,” says lead author Elena Naumova.
The Tufts team included Naumova, professor at the Friedman School and Director of the Initiative for the Forecasting and Modeling of Infectious Disease at Tufts University, and Jeffrey Griffiths, professor of public health and community medicine at Tufts University School of Medicine. Both Naumova and Griffiths have a secondary appointment in the Department of Civil and Environmental Engineering (CEE).
CEE postdoctoral fellow Alexander Liss was also an author on the paper, alongside Irmgard Behlau, research assistant professor in the Department of Molecular Biology and Microbiology at Tufts University School of Medicine, and Jyotsna Jagai of the University of Illinois at Chicago.
