Prolonged Detection of Indigenous Wild Polioviruses in Sewage from Communities in Egypt

El Bassioni, L.·2003·American Journal of Epidemiology

Abstract

Environmental surveillance for polioviruses has been implemented in Egypt. This paper reports on a study in which 130 sewage samples were collected between January 2001 and December 2001 from eight provinces of Egypt. Samples were analyzed by virus isolation in L20B and RD cell cultures, and wild polioviruses were characterized by sequencing of the VP1 protein coding region. Wild type 1 polioviruses were detected in 57% of the sewage samples and 91% of the study sites, only two of which reported paralytic poliomyelitis cases in 2001. Three genetic lineages of a single indigenous type 1 poliovirus genotype were detectable in sewage, and only one lineage was also detected through surveillance for acute flaccid paralysis. Wild polioviruses persisted in the environment despite implementation of oral poliovirus vaccine immunization campaigns. Continued analysis of sewage samples, critical evaluation of immunization coverage, and performance of surveillance for acute flaccid paralysis are proposed as follow-up activities.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In India, sewage sampling helped describe poliovirus circulation epidemiology in places with high vaccination coverage but continuing paralytic polio.

    “In India, sampling of sewage helped to characterize the epidemiology of poliovirus circulation, as previously described [2,4].”
  • Sewage or wastewater sampling for programmatically relevant polioviruses has long been used to supplement AFP surveillance in many countries.

    “Sampling of environmental sewage or wastewater for programmatically relevant polioviruses has been used for many years to supplement AFP surveillance in many countries [2].”
  • In suspected high-risk areas lacking effective AFP surveillance, supplementary surveillance activities, such as sampling community contacts of AFP cases, stool surveys of healthy children, or environmental sampling, have been implemented to increase sensitivity for detecting wild polioviruses.

    “In suspected high-risk areas lacking effective AFP surveillance, supplementary surveillance activities, such as sampling community contacts of AFP cases, stool surveys of healthy children, or environmental sampling, have been implemented to increase sensitivity for detecting wild polioviruses (39, 48, 116, 131, 155, 190, 197).”
  • Sequence relationships are generally summarized in the form of phylogenetic trees and lineage maps.

    “Sequence relationships are generally summarized in the form of phylogenetic trees and lineage maps (10, 12, 48, 84, 87, 118, 177, 179, 226).”
  • Although the Israel and Slovakia isolates each comprise several distinct lineages derived from a common ancestor, this may indicate excellent sensitivity of environmental surveillance for wild polioviruses and VDPVs rather than wider VDPV circulation.

    “Although the Israel and Slovakia isolates each comprise several distinct lineages derived from a common ancestor, this may be an indication of the excellent sensitivity of environmental surveillance for wild polioviruses and VDPVs (48, 115), rather than of wider VDPV circulation.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
