[Puerperal fever. A survey of an epidemic using a case-controlled study]

Abstract

Puerperal fever caused by group A streptococci (GAS) is a most serious infection deriving from the birth canal after childbirth or caesarian section and is manifest by fever and/or local signs of infections. Secundary infections in the umbilicus or skin can occur in the newborn child. As approximately 5% of the Danish population are carriers of GAS in nose, throat, rectum and/or vagina the risk of infection is present especially in childbirth. GAS epidemics in the community result in increased risk of hospital-acquired GAS infections. In the literature it is recommended to take action and implement preventive strategies when two simultaneous cases occur in one department. We describe the course of seven GAS infections in six patients (two children) in the same obstetric ward over a seven-week period, the elucidation by case-control analysis and the implementation of preventive measures. The importance of good hygienic practices is highlighted.
