National surveillance shows fewer influenza cases and a drop in intensive‑care admissions, according to the public health institute Dr Ricardo Jorge (Instituto Nacional de Saúde Doutor Ricardo Jorge). However, authorities warn that overall 'excess mortality' remains above typical seasonal levels, indicating the picture is improving but still worrying in aggregate. Those relying on public healthcare should remain vigilant for local updates and follow NHS guidance if they become ill.
Flu cases fall but 'excess mortality' remains concerning

Context & Explainers
The National Institute of Health Ricardo Jorge (Instituto Nacional de Saúde Ricardo Jorge or INSA) is Portugal's public health institute responsible for epidemiological surveillance, reference laboratories, research and technical guidance for the health system. INSA plays a central role in testing, tracking infectious diseases and issuing scientific advice used by the government and the Serviço Nacional de Saúde, so its findings often shape public-health measures and travel or testing guidance.
Excess mortality is the number of deaths above what would be expected based on historical averages (commonly a multi‑year baseline), and it captures deaths directly and indirectly caused by events like epidemics, heatwaves or healthcare disruptions. Portugal’s public health institute INSA (Instituto Nacional de Saúde Doutor Ricardo Jorge) monitors excess mortality to see the broader impact of seasonal illnesses and other stresses on the health system, so a drop in flu cases does not automatically mean overall mortality has returned to normal. Those following public‑health trends should note excess‑mortality figures because they show the pandemic and other factors’ continuing effect on population health.
