According to AASV, the 2013-2014 PRRS epidemic season continues to be surprisingly different. Using previous four years as a baseline for expected number of breaks, we have observed significantly fewer cumulative new breaks thru December (p = 0.0002). When we look at this on a quarterly basis, we have seen fewer breaks from July to September (p = 0.0139) and from October to December (0.0049). It is interesting because the differences between the years appears to have started back in the summer months.
