Haemophilus septicemia

Haemophilus septicemia is a severe, life-threatening invasive bloodstream infection caused by bacteria of the genus *Haemophilus*, most prominently encapsulated or nontypeable strains of *Haemophilus influenzae* Pathophysiologically, the organism breaches mucosal barriers—often following upper respiratory colonization—and disseminates into the vascular system, triggering a dysregulated systemic inflammatory response characterized by fever, hemodynamic instability, hypoperfusion, and the potentia...

Haemophilus septicemia is a severe, life-threatening invasive bloodstream infection caused by bacteria of the genus *Haemophilus*, most prominently encapsulated or nontypeable strains of *Haemophilus influenzae* The condition most commonly affects vulnerable populations, including infants, young children, older adults, and immunocompromised individuals, such as those with functional or anatomic asplenia or hypogammaglobulinemia

Pathophysiologically, the organism breaches mucosal barriers—often following upper respiratory colonization—and disseminates into the vascular system, triggering a dysregulated systemic inflammatory response characterized by fever, hemodynamic instability, hypoperfusion, and the potential for rapid progression to septic shock, multiorgan failure, or metastatic seeding to the meninges and joints
