- Poliomyelitis (polio) - World Health Organization (WHO)
Poliomyelitis (polio) is a highly infectious viral disease that largely affects children under 5 years of age The virus is transmitted by person-to-person spread mainly through the faecal-oral route or, less frequently, by a common vehicle (e g contaminated water or food) and multiplies in the intestine, from where it can invade the nervous system and cause paralysis
- Poliomyelitis - World Health Organization (WHO)
Wild poliovirus cases have decreased by over 99% since 1988, from an estimated 350 000 cases in more than 125 endemic countries then, to two endemic countries) Symptoms and risk Polio is a highly infectious disease caused by a virus It invades the nervous system and can cause total paralysis in a matter of hours

Los casos provocados por poliovirus salvajes han disminuido en más de un 99% desde 1988, cuando se calculaba que había 350 000 casos en más de 125 países con poliomielitis endémica Ahora hay casos en dos países Mientras haya un solo niño infectado, los niños de todos los países corren el riesgo de contraer esta enfermedad
- Immunization, Vaccines and Biologicals - World Health Organization (WHO)
Bivalent oral polio vaccine (bOPV) – protects against poliovirus types 1, and 3; Monovalent oral polio vaccines (mOPV1, mOPV2 and mOPV3) – protect against each individual type of poliovirus, respectively; If enough people in a community are immunized, the virus will be deprived of susceptible hosts and will die out
- Disease Outbreak News - World Health Organization (WHO)
Vaccine-derived poliovirus is a well-documented type of poliovirus that has mutated from the strain originally contained in the oral polio vaccine (OPV) The OPV contains a live, weakened form of poliovirus
- Poliovirus detections in European Region underscore importance of . . .
28 November 2024, CopenhagenPoliovirus has been detected through routine surveillance of wastewater systems in 3 countries in the WHO European Region (Germany, Poland and Spain) since September this year While no cases have been detected to date, the presence of the virus underscores the importance of vaccination and surveillance, as well as the ongoing risk that any form of poliovirus poses
- Poliomyelitis (polio) EURO - World Health Organization (WHO)
National and regional surveillance systems and laboratories have ensured that no polio case could have been left undetected Today, although the Region has experienced several episodes of wild poliovirus importation, a sustained effort of immunization and disease surveillance helps maintain the Region's polio-free status
- Circulating vaccine-derived poliovirus type 2 (cVDPV2) - Papua New Guinea
On 9 May 2025, the International Health Regulations (IHR) National Focal Point (NFP) for Papua New Guinea (PNG) notified WHO of the detection of circulating vaccine-derived poliovirus type 2 (cVDPV2) from stool specimens of two healthy children from Morobe province, Papua New Guinea (PNG) The detection of wild poliovirus (WPV) or vaccine-derived poliovirus (VDPV), including from samples taken
