ABSTRACT
A recent fatal case of confirmed nosocomial tuberculosis (TB) transmission to a neonate in a kangaroo mother care (KMC) unit highlighted the infection risk to hospitalised neonates in South Africa, a high-burden TB setting. The index case was a 9-week-old infant who presented to another hospital's intensive care unit with severe respiratory distress shortly after discharge from the KMC unit. Contact tracing identified that the infant had been exposed to a postpartum woman with undiagnosed pulmonary TB while in the KMC unit. Molecular testing confirmed nosocomial transmission between the index case and the presumed source case in the KMC unit. We describe the subsequent process of tracing other TB-exposed infants and mothers, the difficulty in confirming TB infection/disease in pregnancy, and the provision of isoniazid preventive therapy in this cohort. We discuss the practical implementation of TB screening approaches in maternity and neonatal wards in high-burden TB settings.

BACKGROUND: Healthcare-associated infections (HAIs) cause substantial morbidity, mortality and healthcare costs. The prevalence of neonatal/paediatric HAI at South African (SA) district and regional hospitals is unknown. OBJECTIVES: To document HAI rates, antimicrobial use for HAI, infection prevention staffing, hand hygiene (HH) provisions and HH compliance rates in neonatal and paediatric wards in two district and two regional hospitals in the Western Cape Province, SA. METHODS: An HAI point prevalence survey (PPS) was conducted in neonatal and paediatric wards at two district and two regional hospitals in the Western Cape during December 2016, applying National Healthcare Safety Network HAI definitions. HAI events and antimicrobial therapy active at 08h00 on the PPS day and during the preceding 7 days (period prevalence) were documented. Provisions for HH and HH compliance rates were observed on each ward using the World Health Organization's HH surveillance tool. RESULTS: Pooled point and period HAI prevalence were 9.9% (15/151; 95% confidence interval (CI) 6 - 15.8) and 12.6% (19/151; 95% CI 8â- 18.9), respectively. Hospital-acquired pneumonia (5/15, 33.3%), bloodstream infection (3/15, 20.0%) and urinary tract infection (3/15, 20.0%) were predominant HAI types. Risk factors for HAI were a history of recent hospitalisation (8/19, 42.1% v. 17/132, 12.9%; p<0.001) and underlying comorbidity (17/19, 89.5% v. 72/132, 54.5%; p<0.004). HH provisions (handwash basins/alcohol hand rub) were available and functional. HH compliance was higher in neonatal than in paediatric wards (125/243, 51.4% v. 25/250, 10.0%; p<0.001). Overall HH compliance rates were higher among mothers (46/107, 43.0%) than nurses (73/265, 27.8%) and doctors (29/106, 27.4%). CONCLUSIONS: Neonatal and paediatric HAIs are common adverse events at district and regional hospitals. This at-risk population should be prioritised for HAI surveillance and prevention through improved infection prevention practices and HH compliance.
