May 13, 2022: The Centers for Disease Control and Prevention listed six Connecticut Counties in the High/Orange category as part of its COVID-19 Community Levels Map. Only Fairfield and New London Counties are listed in the Medium/Yellow category. Residents in these counties should wear a mask indoors in public; stay up to date with COVID-19 vaccines and get tested if they have symptoms. Additional precautions may be needed for residents who are at high risk for severe illness. Visit the CDC COVID-19 Community Levels Map for updates.

Healthcare Associated Infections and Antimicrobial Resistance (HAI-AR)


Welcome to the Connecticut Department of Public Health's (CTDPH) website for healthcare associated infections (HAIs) and antimicrobial resistance (AR). A HAI is an infection that a patient gets while receiving healthcare. Antimicrobial resistance is the ability of bacteria and other micro-organisms to resist being killed by antibiotics or other medicines used to treat them. These pages have information about HAIs and AR and how they are prevented, data on HAIs and AR from healthcare facilities and the state as a whole, and an overview of the CTDPH's HAI-AR Program.

Healthcare Associated Infections - Community Interference (HAIC)


What's New


  1. In collaboration with the Centers for Disease Control and Prevention (CDC) and nine other Emerging Infections Program centers, DPH participated in a major national study of Healthcare Associated Infections (HAI) in hospitals. This study was recently published in the New England Journal of Medicine.
  2. In collaboration with an author from the University of Connecticut School of Medicine, DPH HAI-AR Program and Katherine A. Kelley State Public Health Laboratory staff have published a new scientific article on a serious emerging fungal infection that resist to treatment: Candida auris.
  3. Connecticut Carbapenem-resistant Enterobacteriaceae provider factsheet
  4. Antimicrobial resistance reporting of carbapenem resistance has been expanded from Enterobacteriace (CRE) to include Acinetobacter baumanni (CRAB). Clinical laboratories reporting CRE and CRAB are also requested to submit the isolates to the State Public Health Laboratory.
  5. The DPH HAI Program is offering Infection Control and Assessment Response visits to long term care facilities, and through the IPRO End Stage Renal Disease Network of New England, to outpatient hemodialysis centers. This CDC-funded activity is an on-site consultation service enabling facilities access to tailored assessments and technical assistance to improve infection control.
