An approach is proposed for environmental surveillance of poliovirus by concentrating sewage samples with tangential flow filtration (TFF) followed by deep sequencing of viral RNA. Subsequent to testing the method with samples from Finland, samples from Pakistan, a country endemic for poliovirus, were investigated. Genomic sequencing was either performed directly, for unbiased identification of...
BACKGROUND Early detection and control of vaccine-derived poliovirus (VDPV) emergences are essential to secure the gains of polio eradication. METHODS Serial sewage samples were collected in 4 towns of Mexico before, throughout, and after the May 2010 oral poliovirus vaccine (OPV) mass immunization campaign. Isolation and molecular analysis of polioviruses from sewage specimens monitored the ...
Polioviruses belong to Enterovirus C species and cause severe lesions of the nervous system. In post-polio eradication era, World Health Organisation recommends inactivated polio vaccines for effective long-term protection population. order meet needs global health, it is planned increase use traditional optimised introduce new types that are being developed based on current understanding RNA-c...
BACKGROUND Following successful eradication of wild polioviruses and planned globally-coordinated cessation of oral poliovirus vaccine (OPV), national and global health leaders may need to respond to outbreaks from reintroduced live polioviruses, particularly vaccine-derived polioviruses (VDPVs). Preparing outbreak response plans and assessing potential vaccine needs from an emergency stockpile...
