ABSTRACT
As the goal to eradicate wild polio virus (WPV) is approached, outbreaks associated with vaccine derived polioviruses (VDPV) with neurovirulent properties have emerged. The relevance for the spread of infection by nonparalytic cVDPV cases, with mutations associated with neurovirulence, is discussed with reference to the molecular analysis of a VDPV isolated from a Jamaican child who presented with aseptic meningitis. Potential risks to the Jamaican community resulting from circulation of cVDPV, and critical factors defined by the World Health Organization (WHO) in the global eradication of Polio are analyzed in the context of immunization coverage, and the need to stop all Oral Polio Vaccine (OPV) use once wild polioviruses (WPVs) have been eradicated.
RESUMEN
A medida que nos hemos acercado a la meta de erradicar el virus de la polio salvaje (VPS), se han producido brotes asociados con los poliovirus derivados de la vacuna (VDPV) con propiedades neurovirulentas. El presente trabajo discute la importancia de estos en la diseminación de la infección por casos no paralíticos de cVDPV, en relación con el análisis molecular de un VDPV aislado a partir de un niño jamaicano que presentaba meningitis aséptica. Los riesgo potenciales para la comunidad jamaicana como resultado de la circulación de cVDPV, y los factores críticos definidos por la Organización de Mundial de la Salud (OMS) en la erradicación global de la polio, se analizan en el contexto de la cobertura de la inmunización, y la necesidad de detener todo uso de la Vacuna Oral de la Polio (VOP), una vez que los poliovirus salvajes (PVS) hayan sido erradicados.
