Infection is typified by bacteraemia and meningitis but pulmonary involvement is rare.
Mortality is 10-20%.
The organism may be spread by cross-infection from other mothers, babies or healthcare workers

Normally, after birth, the cardiovascular system undergoes changes;
- Pulmonary Vascular Resistance Falls
- Pulmonary Blood Flow Rises
- Systemic Vascular Resistance is increased
- Ductus Arteriosus Closes
