National Respiratory and Enteric Virus Surveillance System (NREVSS)

The National Respiratory and Enteric Virus Surveillance System (NREVSS) is a program managed by the CDC that tracks the spread and activity of respiratory and gastrointestinal viruses across the United States. Laboratories, hospitals, and health agencies report their test results for viruses like influenza, RSV, norovirus, and others. This information helps public health officials monitor trends, identify outbreaks early, and make informed decisions about prevention and control measures, such as vaccination campaigns or public health advisories. Ultimately, NREVSS enhances our understanding of virus patterns to protect community health more effectively.
