A population-based study, published in Clinical Microbiology and Infection and due to be presented next week at ESCMID Global 2026, has found that influenza was detected in 11% of winter deaths, yet only 17% of these infections were diagnosed before death. The study tested 857 deceased persons across four influenza seasons in Spain, regardless of the reported cause of death.
