| Type of System |
National web-based platform |
National network of public health laboratories |
Network of state health departments that work with CDC |
National laboratory-based system |
Network of state health departments that work with CDC |
| Purpose |
Integrate and streamline previous outbreak reporting systems |
Help CDC compare different norovirus genotypes, link outbreaks to a common source, monitor circulating genotypes, and identify new ones |
Improve timeliness, completeness, and consistency of norovirus outbreak reporting, and quickly assess current norovirus activity, past activity, and impact of future norovirus genotypes |
Timely monitor temporal and geographic circulation patterns of cases of select viruses |
Encourage laboratories within jurisdictions to participate and improve reporting of diagnostic results for select viruses to NREVSS |

| Type of Data Collected |
Aggregate clinical and epidemiological data, including date and location of the outbreak, # of people who became ill and their symptoms, and the pathogen that caused the outbreak. |
Genotype information for norovirus, basic epidemiological data, such as transmission route and outbreak location and patient demographic data. |
A minimum set of epidemiological and laboratory data reported to NORS
Genotype information uploaded to CaliciNet. |
Total # of weekly laboratory tests performed for the seven viruses, the method used for detection, and # of those tests with positive results. |
Same type of laboratory data that NREVSS collects.
Genotype information for specimens sequenced at public health laboratories. |
| Relationship to Other Norovirus Systems |
NORS obtains norovirus genotype data from CaliciNet. |
CaliciNet data linked to NORS to provide genotype information |
NoroSTAT combines a subset of NORS and CaliciNet data. |
NREVSS participation increased through NREVSS Enhanced. |
NREVSS Enhanced increases laboratory participation in NREVSS. |
| Who Reports (Source of Data) |
State, local, and territorial health departments |
Federal, state, and local public health laboratories who complete a CaliciNet certification, or who partners with a certified CaliciNet Outbreak Support Center (CN-OSCs). |
14 participating state health departments (CO, MA, MI, MN, NE, NH, NM, NC, OH, OR, SC, TN, VA, WI) |
Clinical and state laboratories
See list of participating labs |
6 participating state health departments (CO, MI, MN, NV, TN, WI) |
| How to Report |
Outbreak data entered into an online interface |
Lab data electronically uploaded to a national database. |
Suspected and confirmed norovirus outbreaks reported to CDC through NORS and CaliciNet within 7 days of outbreak notice. |
Data electronically submitted to CDC. |
Data electronically submitted to CDC. |
| Data Dissemination |
