Accelerating Electronic Laboratory Reporting (ELR)

Electronic Laboratory Reporting (ELR) is the electronic transmission from laboratories to public health of laboratory reports which identify reportable conditions. ELR has many benefits, including improved timeliness, reduction of manual data entry errors, and reports that are more complete.

Modernizing Mortality Surveillance Systems

The National Vital Statistics System (NVSS) is the nation’s birth, marriage, divorce, and death registry system. The NVSS initiative will transition the current system to electronic reporting to produce more rapid mortality reporting.
