Viruses, 2021 Haïti is at risk for wild poliovirus (WPV) importation and circulation, as well as vaccine-derived poliovirus (VDPV) emergence. Environmental surveillance (ES) for polioviruses was established in Port au Prince and Gonaïves in 2016.

Pediatrics, 1961
A partially immunized recreational school population in central New York has been studied during the course of an outbreak of poliovirus Type I infection. The data indicate that some increased resistance to poliovirus Type I infection occurred following immunization but that the effect was limited to extra-household contact and was not apparent within ...

Molecular Epidemiology of Polioviruses
Clinical Infectious Diseases, 1984Poliovirus isolates can be identified according to their genotypes with use of the technique of oligonucleotide fingerprinting. Fingerprint analysis is performed by cleaving the viral RNA genome with ribonuclease T1 and separating the fragments (oligonucleotides) in two dimensions.

Intratypic serodifferentiation of polioviruses
Virology, 1961Abstract The intratypic serodifferentiation technique described by Wecker has been applied to the antigenic analysis of a number of attenuated and virulent strains within the same poliovirus type. By comparison of plaque inhibition produced by strain-specific immune sera, different pools of the same attenuated strain were found to be serologically ...

Clinical case-driven surveillance for poliovirus remains the cornerstone of monitoring the progress of the poliomyelitis eradication initiative (PEI). It includes notification and careful investigation of cases of acute flaccid paralysis (AFP), timely collection of stool specimens from the patient, and virological examination of the specimens in an ...

The Sabin oral poliovaccine (OPV) is extremely efficacious and safe, despite its inherent genetic instability. While reversion to nearly wild-type phenotype regularly occurs soon after the onset of OPV reproduction in the gastro-intestinal tract of vaccine recipients or their contacts, this is usually not a big problem, provided the vaccine is used ...

Intratypic differentiation of polioviruses
1993The eradication of wild poliovirus from man and environment is a prerequisite for global eradication of poliomyelitis. Large scale vaccination with the live, attenuated poliovirus vac cine is a cornerstone of the eradication programme, but also leads to the ubiquitous presence of vaccine-derived virus.

Are Polioviruses a Cause of Schizophrenia?
British Journal of Psychiatry, 1992Pre-natal infection with polioviruses could contribute to the subsequent development of schizophrenia. The hypothesis draws support from the declining incidence of schizophrenia, the excess of schizophrenic winter births, and the increased rates of schizophrenia among West Indian immigrants.
