CAHAN San Diego Confidentiality:

CAHAN San Diego alerts may contain information on investigations in progress and/or diagnoses that may not yet be confirmed. Access to alerts is therefore restricted to specific medical and public health personnel in San Diego County. Once received by an approved CAHAN San Diego participant, CAHAN San Diego alerts should not be further distributed. Local medical professionals should subscribe individually to receive CAHAN San Diego alerts by using the online subscription feature provided on this website.
