Acute Communicable Disease Control

Because of the Los Angeles County Department of Public Health’s (LAC DPH) recent restructuring, it is vital to refine disease investigation and response protocols for a several communicable diseases. In September 2018, a range of LAC DPH representatives (AMDs, PHNSs, PHNs, and ACDC staff) met to discuss and draft improvements to the protocols. These revisions strive to: streamline investigation and response processes while not jeopardizing public health and safety, reduce DPH workload, improve timeliness and efficiency of disease investigations, as well as prioritize efforts for diseases with greater public health impact. An overview of these revisions will be conducted during a webinar on December 5 and a more in-depth training will be held on December 19 (see below). Further revisions will be made based upon input from staff and the changes will not go into effect until January 14, 2019.

The following are the overall key changes to the protocols that have been proposed.
  • Reduce the number of in-person site visits
    • As appropriate, assess the situation by phone; follow-up by phone as warranted
    • Provide site visits as needed (i.e., for special circumstances) and if requested
  • Reduce AMD sign-off -- Responsibility switches to PHNSs
    • Only for select disease investigations
    • Purpose: Improve timeliness and efficiency and increase autonomy of PHNs
  • Limit exclusion of cases and contacts to those with greater likelihood of disease transmission
    • Reduce workload of follow-up and continued testing
    • Improve relations with the public
