Hamburg Wastewater Shows Wild Poliovirus in First European Finding Since 2010

Officials say routine sewage monitoring detected the virus, with no clinical cases reported.

Overview

  • Germany’s Robert Koch Institute reports the sample was collected on October 6 under a national wastewater surveillance project started in 2021.
  • Genome analysis indicates the virus is closely related to a genetic cluster circulating in Afghanistan, where wild poliovirus remains endemic alongside Pakistan.
  • Health authorities have set up a task force and plan additional sampling to check for any further presence of the virus.
  • The public risk is assessed as very low due to high vaccination coverage with inactivated polio vaccine, though unvaccinated people could still be at risk.
  • The detection highlights ongoing importation risks as the Global Polio Eradication Initiative faces a reported 30% budget cut next year, following recent import-linked cases in Malawi and Mozambique.
