I have a strong inkling that the cycle on this epidemic is over, just like it came to an end for West Nile Virus several years back. It sickened fewer and fewer dogs until it sickened none (except perhaps those severely immune compromised ones). But large numbers of dogs, when tested, showed titers to the virus without ever being sick. It means they were exposed, responded appropriately, and never missed their dinner.
To use the words "quickly spreading across the Midwest" is a red herring now. It is done quickly spreading, and far fewer new cases are presenting now than even a few weeks ago, according to local sources. If the flames are still being fanned, it means there's still hope for vaccine income, even though no protection will be provided.
