Nosocomial pneumonia due to Haemophilus influenzae

Nosocomial pneumonia due to *Haemophilus influenzae* is a hospital-acquired lower respiratory tract infection caused by the Gram-negative coccobacillus *Haemophilus influenzae*, developing 48 hours or more after inpatient admission It primarily affects hospitalized patients, particularly those undergoing mechanical ventilation, older adults, individuals with structural lung disease, or those with impaired airway clearance and consciousness

Pathophysiologically, the condition arises when endogenous or aspirated organisms from the upper respiratory tract colonize the lower airways, triggering alveolar inflammation, exudate accumulation, and impaired gas exchange

Pathophysiologically, the condition arises when endogenous or aspirated organisms from the upper respiratory tract colonize the lower airways, triggering alveolar inflammation, exudate accumulation, and impaired gas exchange Clinically, it is defined by new or progressive pulmonary infiltrates on chest imaging accompanied by systemic and local signs of infection, such as fever, purulent sputum production, leukocytosis, and worsening respiratory failure
