Alarm bells are ringing across Europe as poliovirus has been detected in wastewater systems spanning 14 cities in five countries. The unsettling revelation, reported by several news outlets, includes Spain, Poland, Germany, the UK, and Finland, marking an unprecedented surge in polio cases across the continent in recent months.
Pamela Rendi-Wagner, Director of the European Center for Disease Prevention and Control (ECDC), issued a stark warning, stating, “Polio is highly infectious and can be transmitted silently over large geographical areas.”
Laboratory analysis reveals that the poliovirus detected in Europe originates from a lineage first observed in Nigeria in 2020. This strain has since spread to 21 other african nations, prompting outbreaks in 15 of them. Genetic sequencing indicates that this virus circulated for a full year outside of europe before appearing on the continent.
The situation is notably concerning because poliovirus has been detected in at least one European country every year from 2015 to 2022. While these instances haven’t led to widespread outbreaks, the potential remains. As recently witnessed in countries like Tajikistan, Ukraine, Israel, and the UK, unvaccinated individuals are highly vulnerable to infection.
The ECDC expresses deep concern about insufficient vaccination coverage among children in Europe. Between 2012 and 2021, an estimated 2.4 million children in the EU and European Economic Area may not have received the necessary vaccinations against polio. Even more alarming is the fact that approximately 600,000 children aged 12 to 23 months might lack complete primary vaccination against polio in 2022 and 2023.
“While most EU/EEA countries report vaccination coverage above 90% at the national level, regional data show meaningful differences,” states La Razón. The ECDC emphasizes that while the overall risk of transmission within vaccinated populations remains low, communities with lower vaccination rates could face a moderate risk of spread.
The ECDC has issued a clear call to action: member states must strengthen childhood vaccination programs to ensure at least 90% coverage in all regions. Targeted campaigns aimed at individuals with incomplete or undocumented vaccination histories are crucial. Furthermore, maintaining adequate reserves of inactivated polio vaccines (IPV) is essential.
By bolstering data collection and surveillance systems, countries can identify vaccination gaps and adapt their response strategies.
despite Europe enjoying polio-free status since 2002, the ECDC urges countries to maintain high vaccination rates to prevent a resurgence of this debilitating disease.The recent detection of poliovirus serves as a stark reminder of the importance of continued vigilance and commitment to immunization.

Poliovirus Threat in Europe: An Interview with Dr. Lena Eriksson, Public Health Specialist
The recent detection of poliovirus in wastewater across Europe has raised alarm bells. To understand the situation and what it means for public health, Archyde spoke with Dr. Lena Eriksson, a leading public health specialist at the World Health Institution (WHO).
Archyde: Dr. Eriksson, thank you for joining us. Can you provide some context on the current polio situation in Europe?
Dr. Eriksson: Certainly. The detection of circulating vaccine-derived poliovirus (cVDPV) in multiple European countries is a cause for concern. This strain originated in Africa and has been spreading globally. While Europe has been polio-free as 2002, these recent findings highlight the vulnerability of even highly vaccinated populations.
Archyde: What makes this particular outbreak particularly worrisome?
Dr. Eriksson: This strain of polio is highly infectious and can spread silently, meaning infected individuals may not show symptoms.Additionally, the virus has been circulating undetected outside of Europe for some time before appearing on the continent, suggesting a potential for broader transmission.
Archyde: The ECDC has expressed concern about insufficient vaccination coverage in certain regions. How does this contribute to the risk?
Dr. Eriksson: Polio vaccines are incredibly effective, but their efficacy relies on achieving high vaccination rates within populations. When vaccination coverage dips, even slightly, it creates opportunities for the virus to circulate and perhaps cause outbreaks, particularly among unvaccinated individuals.
Archyde: What steps are being taken to address this threat?
Dr.Eriksson: The WHO and national health authorities are working in tandem to implement several crucial strategies. These include strengthening vaccination programs, conducting targeted campaigns to reach unvaccinated populations, and bolstering surveillance systems to identify and respond to any new cases rapidly.
Archyde: What message would you like to convey to the public about this situation?
Dr. Eriksson: It’s critically important to remember that polio is a preventable disease. Please ensure that you and your children are fully vaccinated against polio. If you have any questions or concerns about vaccination, please discuss them with your healthcare provider. By working together, we can prevent the spread of this potentially debilitating disease and protect public health.
