Surveillance

National Notifiable Diseases Surveillance System (NNDSS)

National surveillance for invasive Haemophilus influenzae disease, including Hib disease, is conducted through the National Notifiable Diseases Surveillance System (NNDSS). NNDSS is a computerized public health surveillance information system that provides the Centers for Disease Control and Prevention (CDC) with weekly data regarding cases of nationally notifiable diseases. Non-invasive Haemophilus influenzae disease is not nationally notifiable. Learn more about NNDSS.


Active Bacterial Core surveillance (ABCs)

ABCs

Invasive Haemophilus influenzae disease, including Hib disease, is also tracked with active laboratory-based surveillance. This is conducted by the Emerging Infections Program's Active Bacterial Core surveillance (ABCs) to:

  • Determine the incidence and epidemiologic characteristics of invasive Haemophilus influenzae disease
  • Monitor impact of the Hib vaccination program
  • Detect possible emergence of disease due to non-b Haemophilus influenzae
  • Determine appropriate verification and validation criteria for serotyping
