Epidemiologic investigations
In accordance with the medical centre’s policy, an epidemiologic
investigation was carried out after every case of postpartum GAS
infection, and it included screening for group A streptococci carriage
from all healthcare workers who treated the patients from the time of
admission. Personnel screening included cultures of the throat, rectum,
and skin lesions (if present). An institutional investigation was
carried out by The Infection Control Unit in cases of GAS
infection-related isolation, and the healthcare workers who had been
screened during the investigation were sent to the national streptococci
reference laboratory for subtyping analysis in cases of
hospital-acquired infection.
