Types of Alerts sent from the Los Angeles County Department of Public Health
CAHAN takes an all hazards approach when a public health response is required. That is, we prepare to respond to all incidents that affect or threaten the public’s health. The following is a list of the types of alerts that are sent from the Los Angeles County Department of Public Health:
- Revised alerts from CDPH or CDC with focus on local relevance/guidance
- Natural disasters that require a public health and/or emergency medical response
- Disease identification prevention, control, treatment, and testing guidelines
- Distribution and availability of medication including vaccine
- Requests for heightened surveillance
- Occurrence of rare or unusual communicable diseases
- Known or suspected disease outbreaks
You can receive CAHAN alerts via e-mail, phone (landline and cellular), Personal Digital Assistant (PDA), fax, or pager, or access them directly on the CAHAN portal.
