Bluetongue disease is a noncontagious, insect-borne, viral disease of ruminants, mainly sheep and less frequently cattle, yaks, goats, buffalo, deer, dromedaries, and antelope. It is caused by Bluetongue virus (BTV). The virus is transmitted by the midges Culicoides imicola, Culicoides variipennis, and other culicoids.

How is bluetongue transmitted in deer?

Hemorrhagic disease does not spread directly from deer to deer, but depends on a biological vector for transmission. Both the epizootic hemorrhagic disease virus and the bluetongue virus are transmitted by Cullicoides, a genus of insects that includes biting midges and no-see-ums.

Can you eat a deer with bluetongue disease?

Unlike some other diseases, it is safe to eat a deer that has/had EHD. No research has shown that the virus can be spread to humans or pets. Even direct bites from a midge fly carrying the disease is of no known threat to animals other than deer.

Can a deer survive EHD?

One of the most common characteristics of deer with the chronic form of EHD is the sloughing or breaking of the hooves caused by growth interruptions. Deer with chronic EHD often become lame due to these hoof problems. Although they are ill for several weeks, they can eventually recover.

Can humans get bluetongue disease?

Bluetongue is an insect-borne viral disease to which all species of ruminants are susceptible, although sheep are most severely affected. It does not affect humans.

How is bluetongue disease transmitted?

Bluetongue virus is spread by insects called biting midges (Culicoides spp.). (vector). Other biting insects, such as ticks or sheep keds, may also transfer the virus. Bluetongue is not contagious and is not spread by contact between animals.

How is bluetongue virus diagnosed?

Agar gel immunodiffusion (AGID) and ELISA are the most used techniques for serogroup determination, although a wide range of different assays have been developed along the years for the same purpose. Serum neutralization is the most frequently used assay for BTV serotype identification.

Does Blue Tongue affect mule deer?

Bluetongue has killed mostly white-tailed deer, but in recent weeks the disease also has been confirmed in some dead mule deer. The animals can die in a few days once symptoms or mouth and nasal discharge occur.

How can you tell if a deer is diseased?

Common signs that may indicate a deer is sick include poor body condition (e.g., rib, hip and/or back bones showing) and lack of alertness (e.g., do not react to sounds around them). Deer with chronic wasting disease may also have lost their fear of humans.

How can you tell if a deer has EHD?

Clinical signs in white-tailed deer usually begin approximately 7 days after infection with the virus. They may have reduced appetite, weakness, and loss of fear of humans. Fever and edema are common and deer with EHD often have a swollen head, neck, tongue, or eyelids. Deer die quickly within 8 to 36 hours.

How do you cure a blue tongue?

No satisfactory medical treatment has been found for animals with blue tongue. Generally, with proper care, most animals recover naturally within 14 days, although severely affected animals may recover more slowly. Isolate affected animals in a shaded area with palatable feed and fresh water.

What disease kills deer?

The state Department of Environmental Conservation is also testing remains of deer from four other locations in Orange, Ulster and Dutchess counties for a viral disease called epizootic hemorrhagic disease (EHD).

Can dogs get EHD from deer?

Can it be spread to humans or pets? EHD is a disease that only affects ruminants, which are hoofed, even-toed animals. Humans and domestic pets such as dogs and cats cannot be infected with the disease. White-tailed deer are particularly susceptible, but it can affect black-tailed deer and mule deer as well.

Can humans get epizootic hemorrhagic disease?

Fast facts. Epizootic hemorrhagic disease (EHD) and bluetongue virus (BTV) are viruses that can infect deer. EHD is more commonly found in white-tailed deer. Neither EHD nor BTV affects humans.
