The Control of Poliomyelitis in Brazil

Risi, João Baptista·1984·Clinical Infectious Diseases

Abstract

A program of mass vaccination with oral polio vaccine was launched in 1980 in Brazil. The aim was to reach in a single day, twice a year, the whole population of children younger than five years of age, irrespective of their vaccination history. More than 20 million children were vaccinated in each of the six campaigns carried out until 1982. Recorded rates of immunization exceeded 90% in the target age group. The incidence of poliomyelitis dropped from an average of 2,330 cases in the 1975-1980 period to only 122 cases in 1981. Provisional figures for 1982 indicate that the total number of confirmed cases will be close to 70. Similar campaigns are intended for 1983 and 1984, but the continuation of this strategy after 1984 is still under discussion.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • CVID is the most prevalent (~1 in 50,000) of the primary immunodeficiency disorders.

    “CVIDisthe most prevalent ( ∼ 1 in 50,000) of the primary immunodeficiency disorders (168).”
  • In upper-income and middle-income countries, survival of patients with primary immunodeficiency disorders is extended by treatment with intravenous immunoglobulin, allowing many patients to lead normal lives.

    “In upper-income and middle-income countries, survival of patients with primary immunodeficiency disorders is extended by treatment with intravenous immunoglobulin, allowing many patients to lead normal lives (69, 168).”
  • Close relatives of CVID patients have a much increased incidence of IgA deficiency, which is also associated with longer times of poliovirus excretion, although excretion rarely persists beyond 6 months.

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.
