Tracking Threats Using Data
CDC gathers data on human infections, pathogens (germs), and reasons or risk factors that cause some people to get a resistant infection. CDC also works with domestic and international partners to strengthen information-sharing networks to fill data gaps and create ways to harmonize how data is reported across countries.
CDC uses several data sources to assess the scope of the problem and track antibiotic resistance. These systems complement each other to provide a comprehensive understanding of known and emerging antibiotic resistance threats. By knowing where and how changes in resistance are occurring, CDC can inform solutions—like containment and prevention, outbreak response, and drug and diagnostic development—to prevent spread and slow resistance.
Antibiotic Resistance Laboratory Network (AR Lab Network), CDC
- The AR Lab Network provides nationwide lab capacity to rapidly detect antibiotic resistance in healthcare, food, and the community, and inform local responses to prevent spread and protect people
- It includes labs in 50 states, five cities, and Puerto Rico, including seven regional labs and the National Tuberculosis Molecular Surveillance Center
- AR Lab Network has a number of components, including Gonococcal Isolate Surveillance Project (GISP), which monitors resistance trends in N. gonorrhoeae bacteria in the U.S.
- Other examples of pathogens (isolates, or pure samples of germs) tested include Acinetobacter, Candida, Carbapenem-resistant Enterobacteriaceae (CRE), Salmonella, and more

Emerging Infections Programs (EIP), CDC
- EIP sites conduct in-depth studies to improve surveillance, prevention, and control of emerging infectious diseases like antibiotic-resistant infections
- The EIP network collects and analyzes patient, healthcare facility, and lab data to track resistant infections across communities and healthcare facilities, identifying gaps and opportunities for prevention

National Antimicrobial Resistance Monitoring System for Enteric Bacteria (NARMS), CDC, U.S. Department of Agriculture (USDA), U.S. Food and Drug Administration (FDA)
- NARMS tracks changes in the antimicrobial susceptibility of certain enteric (intestinal) bacteria found in ill people, retail meats, and food animals in the U.S.
- It helps protect public health by providing information about emerging bacterial resistance, the ways in which resistance spreads, and how resistant infections differ from infections that can be treated with antibiotics
- Learn more: CDC’s NARMS website
National Healthcare Safety Network (NHSN), CDC
- NHSN is the nation’s most widely used healthcare-associated infection tracking system, and includes information on antibiotic resistance and antibiotic use
- It provides facilities, states, regions, and the nation with data needed to identify problem areas, measure progress of prevention efforts, and ultimately eliminate healthcare-associated infections
- Learn more: CDC’s NHSN website
National Tuberculosis Surveillance System (NTSS), CDC
- NTSS collects information on each newly reported case of tuberculosis (TB) disease in the U.S. to measure progress of TB control, prevention, and elimination efforts
- Learn more: CDC’s NTSS website
CDC submits this collected data to the World Health Organization’s (WHO) surveillance system called Global Antimicrobial Resistance Surveillance System (GLASS). GLASS provides a standardized approach to the collection, analysis and sharing of data on antimicrobial resistance at a global level. A component of GLASS called the Emerging Antimicrobial Resistance Reporting (GLASS-EAR) will notify the WHO when new resistance is found, which could influence how these new threats are tracked.

CDC Visual Maps
CDC provides visual maps showing cases of Candida auris (C. auris), carbapenem-resistant Enterobacteriaceae (CRE), and plasmid-mediated colistin resistance (mcr):
- View the map of C. auris, an emerging fungus with some strains resistant to all three major classes of antifungal drugs, a form of resistance not seen before in other species of Candida
View the maps of CRE, which are resistant to nearly all antibiotics, for the following enzymes that can break down carbapenems:
- Klebsiella pneumoniae carbapenemase (KPC)
- New Delhi Metallo-beta-lactamase-1 (NDM-1)
- Oxacillinase-48 (OXA-48)
- Verona Integron-Encoded Metallo-beta-lactamase (VIM)
- View the map of mcr, a gene that makes germs resistant to an antibiotic called colistin, a last-resort drug used to treat difficult-to-treat infections
