Healthcare-associated SARS-CoV-2 transmission in a neonatal unit: the importance of universal masking, hand hygiene and symptom screening in containment.

Following exposure to a health care worker with an influenza-like illness, two preterm neonates and six staff members developed symptoms and tested positive for SARS-CoV-2. This neonatal unit COVID-19 outbreak occurred prior to implementation of universal masking and symptom screening policies. Both neonates and all staff recovered, with no further healthcare-associated SARS-CoV-2 transmission following implementation of effective outbreak containment measures.
