Exploring all-cause mortality surveillance during the Iberian Peninsula power outage, Spain, 28 April 2025

A general power outage affected the Iberian Peninsula on 28 April 2025. We explored all-cause mortality in Spain using the monitoring system MoMo. Starting 28 April, over 3 days, 147 excess deaths (95% CI: − 35 to 330) appeared to occur in the country, corresponding to a 4.2% increase over expected...

description A general power outage affected the Iberian Peninsula on 28 April 2025. We explored all-cause mortality in Spain using the monitoring system MoMo. Starting 28 April, over 3 days, 147 excess deaths (95% CI: − 35 to 330) appeared to occur in the country, corresponding to a 4.2% increase over expected mortality. A larger significant 7.9% increase was estimated in 65–84-year-olds (94 excess deaths; 95% CI: 63 to 125). While MoMo cannot attribute such excesses to specific causes, findings highlight the usefulness of real-time surveillance systems for assessing large-scale emergencies.
