Neonates with H influenzae disease present within 24 hours of birth; these infections are caused by NTHi strains, which colonize the maternal genital tract.

Premature birth, premature rupture of membranes, low birth weight, and maternal chorioamnionitis are associated with H influenzae disease.

Manifestations may be nonspecific and may include those of bacteremia, sepsis, meningitis, pneumonia, respiratory distress, scalp abscess, conjunctivitis, and vesicular eruption.

NTHi is a major cause of pneumonia in infants in developing countries.
