Abstract

We tested whether the effect of influenza activity on invasive pneumococcal disease incidence and severity varies between age and comorbidity groups. Weekly rates of invasive pneumococcal disease were obtained from the Danish National Laboratory Surveillance System (1977–2007). Influenza-like illness data were collected from a sentinel surveillance system at the Statens Serum Institut (Copenhagen, Denmark). We fitted Poisson regression models for invasive pneumococcal disease, with predictors of seasonality, trends and influenza activity, and allowed the influenza activity variable to vary by comorbidity level and clinical presentation. Influenza activity accounted for 8.4% (95% CI 4.8−11.9%) and 6.9% (95% CI 5.4–10.2%) of all invasive pneumococcal disease cases among those aged 15–39 and ≥40 years, respectively, but had no measurable impact among children aged <15 years. Influenza activity was associated with significant increases in the incidence of invasive pneumococcal pneumonia in both children and adults. The association was more pronounced among younger adults without comorbidities. Case fatality also varied seasonally among the elderly, and this variation might be associated with influenza activity. Pneumococcal incidence and the severity of disease varied seasonally and between age groups. The effect of influenza activity on pneumococcal disease varied between children and adults, and this difference was largely due to differences in disease presentation.

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.
