The U.S. Centers for Disease Control and Prevention (CDC) is using wastewater surveillance to monitor trends in antibiotic resistance across the nation. This approach provides community-level data on the presence of genes that make germs resistant to antibiotics, offering a broader picture than clinical testing alone.
According to the CDC's latest data, the National Wastewater Surveillance System (NWSS) has detected genes for resistance to several key antibiotics, including those considered last-resort treatments. The data reveals geographic variations, with certain resistance genes being more common in specific regions of the country.
Public health officials state this surveillance is a crucial tool for understanding the spread of antimicrobial resistance (AMR). Tracking these patterns in wastewater can help identify emerging threats early and guide local prevention and response efforts.
The CDC emphasizes that this data complements traditional public health surveillance. The agency continues to work with state and local partners to expand the network and refine the methods for detecting antimicrobial resistance threats in community wastewater.
