(NAHLN) in collaboration with the VS STAS Surveillance Design & Analysis Unit. Critical notes about the data used in

this report are provided at the end of this report.

Important notes about data used in this report:

Veterinary diagnostic laboratories that have voluntarily reported PEDV testing data to NAHLN

include: University of Georgia – Athens, University of Illinois, Iowa State University, Kansas State

University, Michigan State University—Diagnostic Center for Population and Animal Health,

University of Minnesota, Nebraska Veterinary Diagnostic Center, Ohio Department of Agriculture,

Purdue University, South Dakota State University, and Texas Veterinary Medical Diagnostic

Laboratory-College Station. This data does not include testing conducted at private diagnostic

laboratories, at the NVSL, or for research purposes.

Data summaries provided in this report reflect the most current and complete data available at the

time the report was prepared, and summaries in this report may differ from those provided in past

reports.

PEDV data were collated and summarized by Iowa State University Diagnostic Laboratory from mid-

April through mid-June, 2013; only summary data on positive samples are available for that time

period. Totals for April 2013 only include testing after 4/16/2013.

NAHLN Laboratories began providing more granular information about PEDV testing starting the

week of 6/16/2013, and USDA NAHLN began collating the testing data at that time. During the 2013

federal government shutdown, the University of Minnesota Diagnostic Laboratory collected and

reported PEDv testing data (weeks of 9/22/13 through 10/6/13).

Data on PEDV-negative accessions and samples became available from all laboratories starting

November 2013. Therefore, summaries “total number tested” and “percent positive” are only

calculated for samples tested after November 1, 2013.

In general, a laboratory accession is a set of samples received at the laboratory in which the

samples were collected at a single premises on a single day. Therefore, each laboratory accession

represents a swine herd and each sample represents an individual animal tested for PEDV on a given

date. Because multiple swine within a herd are often simultaneously infected, analyses often use

the laboratory accession as the epidemiological unit of interest.

Age classes are defined as suckling (< 1 month old or still on sow), nursery (1 month up to 3

months), grower/finisher (3 months up to 8 months), and sow/boar (8 months or older).

A single accession can include samples from multiple age classes or samples tested in different

weeks. Therefore, the same accession can be counted in more than one age class category or more

than one testing week summary.

This report does not currently include results of testing on feed samples.

This report only includes PCR testing data at this time, with additional testing types to be added to

the report as information on the performance of new assays becomes available.

Stakeholder feedback on the report content and format is welcome.
