Haemophilus influenzae type b infection

*Haemophilus influenzae* type b infection is a bacterial disease caused by the encapsulated, Gram-negative coccobacillus *Haemophilus influenzae* serotype b Pathophysiologically driven by its polyribosylribitol phosphate capsule, which evades phagocytosis, the pathogen can cause localized mucosal illness or progress to life-threatening invasive diseases, characteristically manifesting as acute bacterial meningitis, epiglottitis, bacteremic pneumonia, septic arthritis, and purulent bacteremia

It predominantly affects infants and young children under five years of age, as well as immunocompromised or asplenic adults, following nasopharyngeal colonization and subsequent mucosal or hematogenous dissemination
