PY - 2018 T2 - Rudolph's Pediatrics, 23e AB - The types of infectious diseases caused by Haemophilus influenzae have changed considerably in recent years as a result of the widespread implementation of routine childhood immunization against type b organisms, but the organism remains an important pathogen. There are 2 major categories of disease caused by H influenzae: infections caused by unencapsulated strains (nontypeable [NTHi]) and disease induced by encapsulated strains (typeable). The unencapsulated strains are responsible chiefly for infections at mucosal surfaces, including conjunctivitis, otitis media, sinusitis, and bronchitis. In contrast, encapsulated strains are associated with invasive disease. Of the 6 encapsulated strains, type b in particular is associated with septicemia, meningitis, cellulitis, septic arthritis, epiglottitis, and pneumonia. Prior to the availability of an effective vaccine, H influenzae type b (Hib) was the most common cause of pediatric bacterial meningitis in the United States.
