CARAlert Annual Report: 2020

The CARAlert Annual Report for 2020 is now available.

The 2020 Annual Report provides the results of analyses of data on confirmed critical antimicrobial resistances (CARs) submitted to the National Alert System for Critical Antimicrobial Resistances (CARAlert) for 2020, and trend data for 2017 to 2020. Key findings include:

  • Excluding new CARs introduced in 2019, there was an overall decrease of 21% in CARs reported in 2020 compared to 2019. Carbapenemase-producing Enterobacterales (CPE) are of most concern, because the number of reports and distribution has increased annually since 2016.
  • Overall, the number of reports of multidrug-resistant Shigella species decreased by 9.7% in 2020. There was however a 3-fold increase in reports of this CAR from both New South Wales and Western Australia during 2020.
