From the Document: "The Laboratory Outreach Communication System (LOCS) is managed by the Division of Laboratory Systems (DLS) in the Center for Surveillance, Epidemiology, and Laboratory Services (CSELS). Currently, LOCS is a functional CDC [Centers for Disease Control and Prevention] mailbox (LOCS@cdc.gov) designed to provide updates and answer questions from clinical laboratories through coordination with professional organizations, CDC programs, and state public health laboratories. The mailbox is managed and monitored by DLS staff and is active during regular business hours. Information and updates are sent to clinical laboratories through professional organizations. This system is available to other CDC programs and may also be used during emergency responses to disseminate information in collaboration with CDC's Joint Information Center in the Emergency Operations Center."
