Who is at highest risk for suffering complications from Hib?

Asplenic patients (people without a spleen or who have dysfunctional spleens such as individuals with sickle cell anemia or celiac disease) are predisposed to the development of serious infections from Haemophilus influenzae, Neisseria meningitides, and Streptococcus pneumoniae.  Persons with underlying medical conditions such as HIV infection, alcoholism, cancer, pulmonary disease, and women who are pregnant may also be at greater risk of an infection that may to lead to complications.  In the case of bacterial meningitis, including H. influenzae meningitis, developing complications or dying is related to age, underlying health of the patient, severity of the disease, and timing of antibiotic therapy.
