This study aimed to estimate the influenza burden in Portugal in 2013/14 - 2018/19 seasons.Key messages: Lower burden of influenza is found in seasons with A(H1) co-dominance. Higher burden of influenza is found in seasons with A(H3) circulation. Health surveillance systems are essential to provide data for a better understanding of the epidemiology and extent of seasonal influenza.engInfluenzaMonitorização e Vigilância em SaúdeEstados de saúde e de doençaconference object
