Limitations of ArboNET data

Surveillance data have several limitations that should be considered when using and interpreting the data.

  1. Under-reporting is a limitation common to all surveillance systems that rely on healthcare providers to consider the disease as a possible diagnosis in a patient, obtain the appropriate laboratory test, and report confirmed to public health authorities.
  2. Surveillance data are reported by county of residence, not the location (county or state) of exposure.
  3. There is a lag in case reporting to CDC and states and territories may publish surveillance data on different schedules than CDC.
