Invasive Haemophilus influenzae type B infections: a continuing challenge.
Invasive Haemophilus influenzae type b infections are a major cause of severe infections in children between 2 months and 5 years of age. Meningitis, arthritis, pneumonia, cellulitis, osteomyelitis, and epiglottitis affect approximately 25,000 patients annually and are a major cause of mortality and morbidity in children. H. influenzae type b clinical syndromes, diagnostic methods, epidemiology, immunity, and treatment are discussed in this review. Although potent antibiotics have long been available for treatment, mortality and morbidity rates have not declined substantially in the last 15 years. Prevention of disease is therefore a continuous medical challenge. Secondary cases can be prevented by identification of the high-risk groups and the application of appropriate techniques, including antimicrobial prophylaxis. Primary prevention is the major goal of current research. H. influenzae type b vaccines currently are available for protection of infants 18 months of age and older. Prevention of primary and secondary disease and future developments, including new vaccine strategies, are stressed.
