EHD is endemic to a lot of southern states. It is always present there. Deer that survive build up an immunity to it.
The northern states seem to get hit hard since the deer have not built up an immunity to it.

We are really getting pounded by EHD this year in TN. Most of the state biologists say this is one of the worst outbreaks they have ever seen. Without question the drought is adding to the problem. And what is so worrisome is that the peak of HD season usually isn't until mid to late September.
As others mentioned HD is endemic in the Deep South (present every year in every location), but the deer have built up immunity to it and rarely die from the disease. The farther north you go, the less frequently outbreaks occur in any given location, hence a higher percent of the deer population have never experienced it and built up an immunity. In the MidSouth, big outbreaks can kill up to 30% of the entire local population. Once you move up into the Midwest, outbreaks occur so infrequently that die-offs can be even worse, with die-offs of as much as 50-60% of the local population.
Hemorrhagic Disease (HD) is the generic name for two groups of diseases; Epizootic Hemorrhagic Disease (EHD) and Blue Tongue (BT). The current outbreak is EHD.

The way i see it this is just mother natures way of managing her animals. When man tries to do what shes done for centuries and does a poor job, then she steps in and corrects the balance and she doesn't care what sex or how big or small the antlers are.
EHD has been around for a long time and there is nothing we can do about it. The animals that survive will be stronger and healthier in the future. h.h.

You nailed it H.H. When we fail at our job of managing the resource, Nature will do it for us, and Nature isn't pretty about it.
In the western and middle sections of my state (TN), hunters are so unwilling to shoot enough deer (even with ludicrously liberal doe limits) that this outbreak is probably a blessing disguise. But it sure is ugly to watch.

That is why the DNR shouldn't give in to folks panicing and calling for drastic reductions in doe permits, that only encourages severe outbreaks again in the future.

EHD hits where it hits, it's not only in places with high deer numbers. I've seen one dead deer in a Zone 3 county in Ky. that has a very low deer population. There is no connection between high deer populations and this disease other than there are more targets for the midges and a lot more deer dead to be found by someone.

That's anywhere south of Alaska.

That's anywhere south of Alaska. Anywhere there is an abundance of this midge along with a over population of Deer. In the field of Biology, it is called "Density Dependent Factors" that is contributing to EHD; where you have to have a vector (midge) inorder to transmit the disease to an over population of Deer in a given area.

BS.....deer density has nothing to do with this disease or it's spread. It doesn't have to be an over populated area to have occurance.

BS.....deer density has nothing to do with this disease or it's spread. It doesn't have to be an over populated area to have occurance. Want to bet? How do you think this EHD is spread? By breathing?? No, it is spread by this midge that bites an INFECTED Deer and then spreads the disease to other Deer in the area. This most offen happens in an over populated area, where the Deer are forced to live closer to one another. Sometimes conditions warrant the midge population to grow (like this year) and thus the disease is spread. Not much can be done to control it, but to reduce either the midge or Deer population. Call it B.S., if you like, but it has happened here, and in surrounding states.

It's BS....population doesn't have anything to do with it. Except where there is a larger deer population, those areas can recover quicker than poorly populated areas. It's the same in ?Indiana as in other states......no different and a lot of the higher populations aren't even effected at all.

Ok here's what a google search turned up here ... wdfw.wa.gov/factshts/ehd.htmQuoted directly "The disease is not contagious from one animal to another, and it is not transferable to humans. It comes from a virus carried by biting gnats that live in or near water and wet, muddy areas. It is transmitted to deer that congregate at such watering holes during warm, dry weather." But then upon further review on this site www.dnr.state.wi.us/org/land/wildlife/whealth/issues/hemorrhagic.htmand again quoted directly 4th paragraph down "HD also can occur in cattle, goats, and sheep; these domestic species have varying susceptibility to the two different viruses that cause HD in deer. The spread of HD from deer to livestock or vice versa has not been proven, but it would be possible for midges to spread the HD viruses to both wild and domestic animal populations. Humans are not at risk for handling or eating venison from infected deer." So I guess your both right.

David is not correct, period. It's spread by a gnat.....number of deer per sq. mile is not a factor is is not mentioned in any of the thousands of pages of data on this disease. It's not mentioned because there is no connection. EHD can occur in any herd, regardless of numbers of animals......same as in cattle, goats and sheep. How many of those are kept in over poopulated conditions because of leasing?

A virus, of any type, has the ability to mutate into a form which would make other species vulnerable to this mutated virus form. A differential diagnosis would be necessary to determine the outcome of such a mutation in how certain species contract the disease while other seem to have some resistance. "Timex" is partly WRONG. <Sorry>

The only thing more deer in a population will do is have more dead deer. More targets of opportunity for the midges. More deer in a herd will make for a faster recovery the next few years.
Percentage wise will still be the same.
The midges carry the disease, they do not spread it from one deer to another. In other words if one deer has it and a non-infected midge bites it they do not become a carrier to another non-infected deer.
Deer will not contract EHD on their own. They need to be bitten by a EHD virus carrying midge.
