healthcare-associated infections (HAI) program

California Antimicrobial Resistance Lab-Epi Alliance

The California Antimicrobial Resistance Lab-Epi Alliance includes clinical and public health laboratorians, infection control practitioners, and epidemiologists working together to address antimicrobial resistance (AR). The goals of the California AR Lab-Epi Alliance are to enhance situational awareness of healthcare-associated AR pathogens, facilitate information and data sharing, and to connect healthcare facilities and laboratories to additional testing resources.

Participants receive updates and join quarterly webinar conferences on AR regional epidemiology and laboratory testing issues resources. To join the California AR Lab-Epi Alliance, please sign up online.

For additional information contact the HAI Program at HAIProgram@cdph.ca.gov.
