Conclusion
This study documented the incidence, clinical course, and outcomes of pregnancy-related GAS infection and sought to elucidate the factors associated with infection severity. Deferral of medical intervention of more than 24 hours from the first signs of infection had the most important impact upon maternal deterioration. Antibiotic prophylaxis during labour may reduce GAS complications, warranting further study to detect specific risk factors and to reassess GAS screening, antibiotic prophylaxis and prevention policies.
