There was a huge drop in cases from 06 to 07 outbreaks but this can be attributed to weather conditions. We are seeing a great increase in cases this year and we anticipate it to possibly be worse than 06 outbreaks.
I donít think we can draw any conclusions from the % survival rate due to the underreporting of the disease. What we have identified is that historically it was reported that the mortality rate was 80% -90% but it appears that if a horse has any vaccination history the mortality rate reduces to below 40%
