Schematic organization of raw data and final processed and anonymized information.
Bullets with letters on the right represent a case.

Results of PRRSV cases tested by RT-qPCR over time.
Fig 4.
Percentage of RT-qPCR-positive results for PRRSV cases over the total number of cases per season.
Each point represents a season within a year. Season are represented as follows: 1-Wi = Winter; 2-Sp = Spring; 3-Su = Summer, and 4-Fa = Fall.
Fig 5.
Geographical distribution of PRRSV RNA detection by RT-qPCR.
A: overall distribution of all cases tested for PRRSV RNA. B: only cases with positive results for type 2 (North American)-PRRSV. C: only cases with for positive results type 1 (European)-PRRSV. D: only cases with a positive result for PRRS NA and positive result for PRRS EU. For VDL client confidentiality purposes, only states with hog inventory above 2 million heads [16] have numbers in the maps. Gray color shows the states with no cases.

Each bar represents a year season, and each color represents a specimen type.
