Modeling Infectious Diseases in Healthcare Network (MInD - Healthcare)

Supporting Research that Models the Spread of Healthcare-Associated Infections (HAIs) and Antibiotic Resistant (AR) Infections

Healthcare-associated infections (HAIs) are linked with high rates of disease and death. In the last few decades, HAIs, including those that are increasingly resistant to antibiotics, are becoming much more common and a significant public health threat.

In order to develop evidence-based prevention strategies, we must understand how HAIs are transmitted within healthcare facilities and in the community. MInD-Healthcare will support innovative transmission modeling research to expand our knowledge of what drives the spread of HAIs and estimate the benefits of preventive measures.  The 6 newly awarded sites will work collaboratively to increase our understanding and response to HAIs and antibiotic-resistant (AR) infections in the US. Each site has also received supplemental funding to conduct additional work to support the Coronavirus disease 2019 (COVID-19) response efforts. Additional information concerning COVID-19 modeling can be found here (

What is CDC doing to better understand the transmission of HAIs and assess prevention strategies?

CDC funds innovative research to:

  1. Develop tools and methods to understand the spread of HAIs and AR infections
  2. Predicting outbreaks and burden trends of HAI pathogens
  3. Assess the potential effects of intervention strategies

Multi-scale Modeling and Phylodynamics for HAIs

AR and HAI aims:

  • Develop improved approaches for inferring routes of acquisition of HAIs and optimizing HAI surveillance and control
  • Develop and apply methods to explore the fitness effects of antibiotic-resistant traits on pathogen phylogenies and speed the methods to quantify fitness for large numbers of strains

Contact Network Transmission Modeling of HAIs

AR and HAI aims:

  • Develop and validate longitudinal models of HAI risk that incorporate the individual patient’s history prior to hospitalization, including community and healthcare exposures. Assess the effects of latent HAI transmission and transmission by asymptomatic carriers.
  • Develop and validate fine-grained models of HAI transmission that overlays all aspects of hospital operations on top of a detailed spatial model of the hospital, and evaluate the effectiveness of non-pharmaceutical interventions through agent-based simulations that are sufficiently fine-grained to demonstrate emergent behaviors such as combinatorial cascades
  • Develop and validate statistical and mathematical models of regional HAI transmission that reflect the underlying patterns observed in practice and creating publicly available tools to guide surveillance and effective regional outbreak response

  • Applying deep learning methods to forecasting demand on ICU beds based on facility operational features, patient demographics, and diagnostic test results
  • Developing, prototyping, implementing and deploying new technology to measure the acquisition, natural history, and transmission of COVID-19 in healthcare facilities

These investments are part of CDC’s Antibiotic Resistance Solutions Initiative and empower the nation to combat AR and the threat it brings to people, modern medicine, and to the healthcare, veterinary, and agriculture industries. These investments work toward meeting national goals to prevent drug-resistant infections.
