[Impact of the SARS-CoV-2 pandemic on a human milk bank].

Introduction: the pandemic caused by SARS-CoV-2 led to the declaration of the state of sanitary alarm between March and June 2020 in Spain. The activity of human milk banks was affected during that period, making it necessary to implement new measures in order to promote milk donation and diminish said impact. Method and objective: the aim of the study was to evaluate the impact of the state of alarm decreed from March 14 to June 22, 2020 on the breastmilk bank at Hospital Virgen de las Nieves, Granada, Spain, in comparison with the same period during the previous year. To that end, a retrospective descriptive study was undertaken in which the activity indicators of the breastmilk bank were collected and compared to data from the milk bank at Hospital Virgen de las Nieves and peripheral collaborating centers. Results: during the first state of alarm in 2020 a global reduction was seen in new donor registrations, number of donors who donated milk, donated mean volume per mother, and total volume of received and pasteurized milk. However, new registrations and number of donors who donated milk during this period increased in Granada's breastmilk bank. Discussion: the new measures adopted in the breastmilk bank in Granada, such as encouraging milk donation in mothers with admitted newborns in the Neonatal Unit, increasing information given to mothers, and home collection of donated milk, allowed to attenuate the impact of the pandemic while guaranteeing safety.
