Missouri Conservation Department seems to think Hemorrhagic, Blue Tongue and CWD are different types of diseases.
Hemorrhagic and Blue Tongue is spread by the same biting insects and both of these diseases are not always fatal to deer.
CWD is fatal and spread through infectious prions in saliva, urine or feces from infected animals.
We have cases of all three diseases in Missouri, however it's claimed that CWD as of now is contained in six Missouri counties.
The county I live in ( DeKalb) is not supposed to have any known cases of CWD.
Whatever it is that's killing our deer we sure lost a lot of them in our county.
