Portugal has recorded excess mortality since the first week of December, according to new data released national health authorities, raising concerns about seasonal health pressures and vulnerabilities among at risk populations. The figures were disclosed the Directorate-General of Health and the National Institute of Health Dr. Ricardo Jorge, which jointly monitor mortality trends across the country.
Excess mortality refers to the number of deaths above what would normally be expected based on historical averages for the same period. Health experts use the measure to assess the broader impact of factors such as infectious diseases, extreme temperatures and pressure on healthcare systems. According to the latest assessment, Portugal has been experiencing sustained excess deaths since early December, coinciding with the onset of winter.
Officials said the increase is likely linked to a combination of seasonal illnesses and environmental factors. Respiratory infections, including influenza and other winter viruses, tend to rise sharply at this time of year, particularly among older adults and people with chronic conditions. Cold weather can also exacerbate cardiovascular and respiratory problems, contributing to higher mortality during winter months.
The health authorities noted that hospitals and primary care services have been under increased strain in recent weeks. Emergency departments have reported higher patient volumes, especially for respiratory symptoms, while staff shortages and delayed access to care may be amplifying risks for vulnerable individuals. Although Portugal’s health system remains operational, officials acknowledged that sustained pressure can have knock on effects on outcomes.
DGS and INSA stressed that excess mortality does not point to a single cause, but rather reflects overlapping pressures on public health. They said detailed analysis is ongoing to determine how much of the increase can be attributed to specific illnesses, delayed treatment or other contributing factors. Similar patterns of excess mortality have been observed in several European countries during winter periods, particularly in years marked strong flu circulation.
Public health experts emphasised the importance of preventive measures. Vaccination against seasonal influenza and Covid 19 remains a key tool in reducing severe illness and deaths, especially among the elderly. Authorities urged people with underlying health conditions to remain vigilant, seek medical advice early and avoid exposure during peak infection periods where possible.
The data has also renewed discussion about long term demographic trends in Portugal. The country has one of the oldest populations in Europe, making it more susceptible to winter mortality spikes. Analysts say this demographic reality underscores the need for targeted protection strategies during colder months, including community outreach and improved monitoring of isolated elderly individuals.
Health officials said they are closely tracking mortality patterns in real time and will update guidance if the situation worsens. They also highlighted the importance of coordination between hospitals, primary care providers and social services to ensure timely support for those most at risk.
Despite the rise in deaths, authorities cautioned against alarmism. Excess mortality is a recognised seasonal phenomenon, and its scale can fluctuate significantly from year to year. However, they acknowledged that sustained excess levels warrant close attention, particularly as health systems continue to recover from recent years of strain.
The DGS and INSA said transparency in reporting is essential for public trust and effective response. identifying excess mortality early, they aim to guide policy decisions, allocate resources more effectively and inform the public about potential risks.
As winter continues, health officials are urging the public to take preventive steps, remain attentive to symptoms and support vulnerable family members and neighbours. Whether mortality levels ease in the coming weeks will depend on how seasonal illnesses evolve and how effectively pressure on the health system can be managed.
