Because high latitude environments are experiencing rapid rates of change, and the distribution of POWV in North America is unclear, documenting potential sylvatic hosts of this pathogen is critical to evaluating its capacity to emerge into human populations.
However, we encountered many instances of incomplete, ambiguous, and unclear documentation in the chart documents in a manner that appears to have been experienced by other researchers who have tried to document antibiotic timing[ 3, 4, 8, 9, 13, 15, 19, 20].

If any of this information could not be determined from study description, "unclear" was documented.
It is unclear how the documents made their way to the group.
It was unclear how the documents, if confirmed as authentic, could have been obtained.
