Contact tracing, use of surgical masks, hand hygiene and social distancing represent a bundle of effective measures to control SARS-CoV-2 spreading among healthcare workers in a paediatric hospital

Severe Acute Respiratory Syndrome Coronavirus-2 (SARSCoV-2) is the causative agent of pandemic coronavirus disease 2019 (COVID 19). Protection from virus exposure in children’s hospital is a pivotal aspect of SARS-COV-2 pandemic control. Healthcare workers (HCW) could play an important role in viral infection in-hospital spread. Infection control measures were thus implemented to protect fragile patients and healthcare workers.We retrospectively described a HCW infectionscase-series due to SARS-CoV-2 from February 24th to July 31stat the IRCCS Istituto Giannina Gaslini. Seven separate cases of SARS-CoV-2 infection were observed among healthcare workers, with a total of 395 contacts, and 23 (6%) secondary case. A program of contact tracing and quarantine of SARS-CoV-2 positive HCW, screening of asymptomatic HCW, use of surgical masks, hand hygiene, social distancing and use of PPE in COVID-19 cases assistance prevented the spread of the virus to patients and blocked the diffusion within the hospital
