• Description:
  Background:
  
  Since the introduction of Haemophilus influenzae serotype b (Hib) conjugate vaccines in the United States, invasive H. influenzae disease (Hi) epidemiology has changed and racial disparities have not been recently described.
  
  Methods:
  
  Active population- and laboratory-based surveillance for Hi was conducted through Active Bacterial Core surveillance (ABCs) at 10 U.S. sites. Data from 2008–2017 was used to estimate projected nationwide annual incidence in cases/100,000.
  
  Results:
  
  During 2008–2017, ABCs identified 7379 Hi cases. Of 6705 (90.9%) patients with reported race, 76.2% were White, 18.6% were Black, 2.8% were Asian/Pacific Islander (PI), and 2.4% were American Indian and Alaska Native (AI/AN). Nationwide annual incidence was 1.8 cases/100,000. By race, incidence was highest among AI/AN populations (3.1) and lowest among Asian/PI populations (0.8). Nontypeable Hi (NTHi) caused the largest incidence within all races (1.3), with no striking disparities identified. Among AI/AN children aged <5 years, incidence of Hi serotype a (Hia) was 16.7 times higher and Hib incidence was 22.4 times higher than among White children. Though Hia incidence was lower among White and Black populations compared to AI/AN, Hia incidence increased 13.6% annually among White children and 40.4% annually among Black children aged <5 years.
  
  Conclusions:
  
  While NTHi causes the largest Hi burden overall, AI/AN populations experience disproportionately high rates of Hia and Hib, with the greatest disparity among AI/AN children aged <5 years. Prevention tools are needed to reduce disparities affecting AI/AN children and address increasing Hia incidence in other communities.
