NCIRD Surveillance Systems

Viral Surveillance

• Respiratory Virus Laboratory Emergency Department Network Surveillance (RESP-LENS)
  This interactive dashboard tracks emergency department visits for laboratory-confirmed severe acute respiratory coronavirus type 2 (SARS-CoV-2),  influenza (flu), and respiratory syncytial virus (RSV).
• Respiratory Virus Hospitalization Surveillance Network (RESP-NET)
  This site comprises three platforms that conduct population-based surveillance for laboratory-confirmed hospitalizations associated with COVID-19, Influenza, and Respiratory Syncytial Virus (RSV) among children and adults.
• National Emergency Department Visits for COVID-19, Influenza, and Respiratory Syncytial Virus
  This site provides a combined view of emergency department visit data for multiple respiratory conditions as tracked by the National Syndromic Surveillance Program (NSSP).
• National Respiratory and Enteric Virus Surveillance System (NREVSS)
  This laboratory-based system monitors temporal and geographic circulation patterns of RSV, HPIV, HMPV, respiratory and enteric adenoviruses and rotavirus detections.
• National Enterovirus Surveillance System (NESS)
  This passive, voluntary surveillance system monitors laboratory detections of enteroviruses and parechoviruses in the United States.
• U.S. Influenza Surveillance
  The Influenza Division at CDC collects, compiles, and analyzes information on influenza viruses and disease activity year-round in the United States.
• CDC’s WHO Collaborating Center for Surveillance, Epidemiology, and Control of Influenza
  CDC, the WHO collaborating center in Atlanta, conducts research and analysis on information and samples from around the world to monitor changes in influenza viruses with the aim of reducing influenza disease impact through the use of vaccines.

Bacterial Surveillance

• Active Bacterial Core Surveillance (ABCs)
  This laboratory- and population-based surveillance system for invasive bacterial pathogens provides an infrastructure for public health research.

Vaccine Impact

• New Vaccine Surveillance Network (NVSN)
  Seven U.S. study sites focus on population-based surveillance and data collection on the use and impact of vaccines and the impact of vaccine policies.
• Human Papillomavirus (HPV) Vaccine Impact Monitoring Project (HPV-IMPACT)
  Since HPV infections and related diseases are not nationally notifiable, CDC and partners have created a surveillance system to monitor the impact of HPV vaccine on HPV-related cervical disease.
• Influenza Vaccine Effectiveness Network
  CDC uses four primary networks to estimate influenza vaccine effectiveness. Monitoring the performance of influenza vaccines is important for understanding and improving the benefits of vaccine.
