Two international locations reported new polio instances this week: Pakistan, with 3 extra wild poliovirus sort 1 instances (WPV1), and the Democratic Republic of Congo (DRC) with a vaccine-derived case, in accordance with the most recent weekly report from the World Polio Eradication Initiative (GPEI).
Pakistan’s 3 new instances of untamed poliovirus sort 1 (WPV1) occurred in December, thus elevating the nation’s 2024 whole to 73 polio instances.
Within the DRC, one circulative vaccine-derived poliovirus sort 1 was reported, however no different particulars have been supplied.
Report on current wastewater detections in Europe
In different polio information, yesterday European researchers revealed a report in Eurosurveillance detailing the detection circulating vaccine-derived poliovirus sort 2 (cVDPV2) in wastewater samples in Finland, Germany, Poland, Spain, and the UK.
All detections have been made within the second half of 2024. The UK had essentially the most detections, with 12, adopted by Poland (8), Germany (7), Finland (5), and Spain (2). Detection dates ranged from September 16 by way of November 18.
The authors mentioned genomic evaluation exhibits excessive sequence id between isolates from totally different international locations, suggesting genetically associated cVDPV2 strains.
This noticed genetic range argues for almost simultaneous importations of genetically associated viruses.
“This noticed genetic range argues for almost simultaneous importations of genetically associated viruses having occurred into totally different European areas from an unknown nation or space throughout a brief time period though different explanations are potential, similar to some transmission occurring between European international locations,” they wrote.
