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)
Invasive Haemophilus influenzae disease, including Hib disease, is also tracked with active laboratory-based surveillance. This is conducted by the Emerging Infection 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
