Epidemiology of Mycoplasma pneumoniae Infection in Families

Foy, Hjordis M.·1966·JAMA: The Journal of the American Medical Association

Abstract

The transmission and clinical manifestations of infection withMycoplasma pneumoniaewere studied in 114 families in which there was a case of atypical pneumonia.M pneumoniaewas isolated from a throat culture of the index pneumonia patient in 36 of these families. Transmission to other family members occurred in 23 of the 36 families. In these 23 families, 84% of the children and 41% of the adults were infected. The index cases are included. Of the total 59 patients with family-contact infections, 42 had lower-respiratory-tract symptoms, 6 had pharyngitis alone, 9 (all children) were asymptomatic, and 2 had probably unrelated symptoms. The time intervals between cases within a family suggested a median incubation period of 23 days. Treatment with tetracycline seemed neither to cure the symptoms completely nor to abolish the carrier state that often lasted one to three 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.
