Improving Capacity for Public Health Laboratories in California CHEAC Annual Meeting October 9, 2019
Laboratories Disease Enforce NGHA surveillance regulations Investigate infectious food- Provide lab testing when water- and no other resources vector-borne available diseases Lab tours and Laboratory outreach events competency and training MOUs, networks Continuous and quality collaborations improvement with other labs Applied research from observations during Participate in routine testing strategic planning

Research Public Health Labs Clinical Response Regulation
Public HealthLaboratories • Focused on health of population (notindividual clinical treatment) • Test human, animal and environmental samples • T est for reportable diseases, emergingdiseases and outbreaks • Often have tests not available in commercial laboratories; can develop new tests asneeded • Required to follow clinical and environmental testing regulations, employ licensedpersonnel, and pass regulatory inspections
Laboratory ResponseNetwork • National laboratory network to detect biological, chemical and radiological threats and emerging pathogens • Categories of laboratories: Sentinel, Reference, Advanced and National • California Public Health Laboratories participate at Sentinel, Reference and Advanced levels https://emergency.cdc.gov/lrn/

New Technologies • Whole Genome Sequencing (WGS) and Next Generation Sequencing (NGS) • PulseNet, TB, Shigella, Influenza, Norovirus, Measles, Hepatitis A • T echnical consultation for WGS wet lab Serratia outbreak – HAI Investigation applications and data analysis Google images Historical Legionella isolates
LRN Infrastructure: Best Practices • Network for disease surveillance and outbreak detection • Standardized methods & equipment through regularly updated lab protocols and communications with Sentinel and Reference PHLs • Functional redundancy • Communication and collaborations among different jurisdictions • Resource for guidance and training • Relationships with local clinical labs • Relationships with first responders • Important for PHLs to be involved in preparedness exercises and Homeland Security drills to maintain communication and contacts
Frequently asked questions • How many BSL‐4 labs are there in California? • None • Only 14 Advanced BSL‐3 laboratories in the US • Can we borrow a BSL‐3 lab in an emergency? • Unless everything is exactly the same, would need days‐weeks to start testing • Clinical regulations (CLIA) require test validation, equipment verification and personnel competency for any changes
