Abstract

Human granulocytic anaplasmosis, a deer tick-transmitted rickettsial infection caused by Anaplasma phagocytophilum, is a common cause of undifferentiated fever in the northeast and upper Midwest United States. Patients are often initially diagnosed with a mild viral infection, and illness readily resolves in most cases. However, as many as 3% develop life-threatening complications and nearly 1% die from the infection. Although coinfections with Borrelia burgdorferi and Babesia microti occur, there is little evidence to suggest synergism of disease or a role for A phagocytophilum in chronic illness. No vaccine is available.

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.
