| Outbreak | Main European Pattern | Public Health Implications |
|---|---|---|
| COVID-19 (2020–2025) | Dominant health crisis of the period; early waves caused high mortality, while Delta and Omicron renewed transmission and pressure on health systems. | Excess mortality, social and economic disruption and a need for coordinated preparedness, communication and equitable vaccination. |
| Mpox (2022) | Rapid rise in cases in several Western European countries and concentration among men who have sex with men. | Called for targeted surveillance, community engagement, non-stigmatizing communication and focused vaccination. |
| Measles resurgence/poliovirus detection | Measles resurgence linked to falling vaccination coverage, pandemic-related service disruption and misinformation, especially in Eastern and South-Eastern Europe, while 2024 VDPV2 wastewater detections in five countries highlighted continuing polio risk. | Made catch-up immunization and restored confidence in routine vaccination urgent. |
| Legionellosis (Poland, 2023) | Cluster centered on Rzeszow and nearby areas, likely associated with the water supply system and affecting mainly older or immunocompromised people. | Highlighted the need for water-quality monitoring, environmental investigation and rapid local response. |
| Acute hepatitis of unknown origin in children (2022) | Europe recorded notable pediatric cases; some were severe and required liver transplantation, while the cause remained uncertain. | Strengthened the case for rapid syndrome-based surveillance and coordinated etiologic investigation. |
| Health Burden | Main Drivers/Pattern | Public Health Implications |
|---|---|---|
| Mental health | Isolation, uncertainty, service disruption and prolonged stress raised depression and anxiety, suicidal behavior and other mental health problems, especially among children, adolescents and health workers. | Longer waiting times, unmet need and concern about suicide trends. |
| Obesity | Sedentary behavior, poorer diet, processed food intake and food insecurity worsened weight-related risk, especially in children and adolescents. | Higher long-term burden of cardiovascular disease, diabetes and other chronic conditions. |
| Chronic diseases | COVID-19 redirected resources, delaying routine visits, screening and treatment for cardiovascular, respiratory and other chronic conditions. | Worse disease control, preventable deaths and later diagnosis. |
| Type II diabetes mellitus | Lower activity, poorer diet and delayed monitoring led to late diagnosis and weaker glycemic control. | Greater cardiovascular, renal and neurologic complication risk; stronger primary care follow-up is needed. |
| Digital addiction | Online schooling and digital social life increased screen exposure, particularly among adolescents. | Sleep problems, lower physical activity, concentration difficulties and poorer mental health. |
| Antimicrobial resistance | Antibiotic overuse and weak infection prevention sustained the spread of resistant microorganisms in human and animal settings. | A persistent “silent epidemic” needing stewardship, surveillance and a One Health response. |
