Emergence of Candida auris

Emergence of Candida auris in Healthcare Facilities in Northern California and Increase in Incidence of Carbapenemase-Producing Organisms

Alameda County Public Health Department (ACPHD) is notifying healthcare providers of the identification of a patient with Candida auris (C. auris) colonization in our jurisdiction in January 2023 transferred from an Acute Care Hospital in Contra Costa County. The patient was identified upon admission screening and had no known risk factors or exposures in healthcare facilities outside of Northern California. Due to the presence of C. auris locally, ACPHD encourages healthcare facilities to screen patients on admission from any long-term acute care hospital (LTACH), subacute/ventilator-equipped skilled nursing facility (vSNF) and any healthcare facility in Nevada state.

Please see full health advisory for detailed information.

Information to Healthcare Providers on Doxy-PEP

There is a new opportunity for prevention of sexual transmitted infections (STIs) for Alameda County residents called doxycycline post-exposure prophylaxis, or doxy-PEP.   This letter provides provisional guidance to healthcare providers on this strategy. As new information becomes available this guidance may be modified. Doxy-PEP is doxycycline 200 mg taken within 72 hours of sex (preferably within 24 hours of sex).

  • Healthcare providers should counsel gay men and other men who have sex with men, and transgender people regarding doxy-PEP as a part of comprehensive sexual health counseling.
  • Gay men and other men who have sex with men and transgender people who have had a recent STI and who are not taking HIV PrEP should be counseled about HIV PrEP and new long-acting formulations (cabotegravir).
  • Adult gay men and other men who have sex with men, and transgender women who are interested in doxy-PEP and who have had a recent STI (chlamydia, gonorrhea or syphilis in the last year), or who are taking HIV PrEP, or who have had more than 1 oral or anal condomless sex partner in the last year, or who are people living with HIV, should be offered doxy-PEP.
  • Doxycycline can be taken as often as every day, depending on frequency of sexual activity, but individuals should not take more than 200 mg within a 24-hour period.

For any questions, please reach to Alameda County Public Health, or 510-267-3220
