CaliciNet is the national database that contains what type of data?

• A. Norovirus sequences
• B. Bacterial genome sequences
• C. Foodborne illness outbreak reports
• D. Consumer complaint data

Answer: (A)

CaliciNet is a national surveillance system for norovirus outbreaks that focuses on molecular data to track the virus across outbreaks. The data it stores are norovirus sequences obtained from outbreak samples, along with linked epidemiologic details. Having sequence data enables scientists and public health officials to compare strains, see how they spread, and identify whether seemingly separate outbreaks are connected by the same virus. This is why the best answer is that CaliciNet contains norovirus sequences. It’s not about bacterial genomes, consumer complaints, or outbreak reports alone, though those reports sit alongside the sequencing data to support investigation and response.
