Blue Tongue Deer Disease

Blue tongue deer disease is a common disease of deer. This article will discuss its symptoms, causes, transmission, and prevention. This disease can cause severe health problems in deer. In addition to its appearance, deer can display hemorrhaging in their rumen and intestines. They may also display ulcers on their tongue, dental pad, and palate. They may also lose papillae and show signs of emaciation despite being fed.


Blue tongue deer disease (EHD) is a disease that can affect deer. The symptoms of this disease vary from no symptoms to sudden death. The early stage of this disease is not characterized by symptoms, but deer with the disease often look weak and sick. They may have a high fever and have excessive salivation. Some deer will also experience bleeding or ulcers in their mouths and face. Their lungs and eyes may also become affected. Although the disease is typically fatal, some animals may survive the disease.

The disease can also infect mule deer, bighorn sheep, and elk. Infected deer usually die within 24 hours. The virus is transferred from infected deer through a variety of routes, including the subcutaneous, intramuscular, and oral routes. This disease is highly contagious and can spread to a variety of wildlife species. The disease is a serious threat for deer.

Blue tongue disease is an infectious disease that can kill large numbers of deer. While most animals don’t develop any symptoms, those that do may die in as little as a week. Even those without symptoms may have a slow recovery or require euthanasia due to welfare considerations. It is most common in white-tailed deer and is caused by the bluetongue virus. Some deer may show no symptoms at all, but a dead deer may show swollen neck and eyelids.

Once symptoms appear, the next step is to test for the virus. Depending on the type of infection, a blood sample may show up in the affected animal. The virus may be able to cause hemorrhages in different tissues and organs. Vaccination can prevent the spread of the disease.

Infected deer may have a fever and show sloughing of hoof walls. They may also be unable to stand for a long time. The disease is transmitted through the bite of tiny, biting midges known as Culicoides. Infected deer can be seen for several weeks after the first hard freeze.

The diseases are spread by infected white-tailed deer. The disease is usually fatal to deer. However, it can affect domestic sheep and cattle.


In case of deer suffering from blue tongue deer disease, the disease causes various symptoms like emaciation, swelling of the tongue and neck, dehydration and internal hemorrhaging. In most cases, the disease will kill the deer in about 36 hours. There is no known treatment for the disease. Fortunately, the disease is not transmitted to humans and pets.

This disease is spread by biting midges. It can also be passed on from mother to fetus. The symptoms of blue tongue are very similar to those of EHD virus. The infected animal will experience fever, nasal discharge, swollen tongue, and facial swelling. In some cases, the animal will have foot lesions, leading to knee-walking and lameness. In severe cases, the disease may even lead to ulcers on the mouth and stomach.

The disease is also known as EHD, which is transmitted by midges. Deer infected with this disease often have a high fever and are found near water sources. This is an ideal habitat for the midges that transmit the disease. Therefore, it is important to contact the regional office of the MDIFW to check the status of the affected deer.

The disease has recently been detected in deer in New York State. It is closely related to the Epizootic Hemorrhagic disease virus. This virus has been detected in several mid-Atlantic states this year. In late August, two white-tailed deer were found dead in Schodack, Rensselaer County, where one had been diagnosed with the disease.

In late summer and early fall, a higher risk of infection in deer occurs. The incidence of this disease increases as the midge population increases. Infected deer can also be observed several weeks after the first hard frost. While it is difficult to determine the exact cause of blue tongue deer disease, proper identification and control are vital for prevention.

Hemorrhagic disease is a widespread disease caused by two closely related viruses. These viruses infect white-tailed deer and can cause significant mortality events in the northern U.S. They also cause serious disease in domestic ruminants, including cattle and sheep. Although neither BT nor EHD affects humans, both are highly contagious and can infect both animals.


Deer are vulnerable to this disease and are especially susceptible to outbreaks in areas where there are abundant populations of elk. This virus causes hemorrhagic disease, which is fatal. It is spread by biting midges that breed in small pools of standing water. Symptoms of the disease include loss of appetite and fear of humans. A deer may also appear swollen in neck, eyelids, and tongue.

While bluetongue is a relatively uncommon disease, it has been found in countries across the world. It is also spread by domestic yak. When infected, calves are born underweight and may experience congenital deformities or abortions. Bluetongue can also be transmitted through the semen of infected bulls, which is why export restrictions on these animals are in place.

While the disease was previously confined to subtropical and tropical regions, it has recently been found in temperate areas, including the United Kingdom and Australia. In the European Union, bluetongue has been found in the Netherlands and Belgium, as well as in Denmark and central France. However, the virus does not infect humans in this region.

The disease is caused by a virus called Bluetongue virus, which is closely related to several other viruses. Viruses that cause deer disease and African horse sickness cross-react with BTV. The virus replicates in arthropod and mammalian host cells and causes the disease. It has 25 serotypes that have been identified so far.

Deer may be highly susceptible to BT if they are in areas that experience frequent outbreaks of this disease. However, some deer populations may have developed natural immunity to the disease. This makes vaccination the best way to minimize losses from BT. Vaccination breaks the transmission cycle from an infected animal to its vector. However, the vaccine must be designed to protect against a specific strain of the disease.

Symptoms of the disease include a blue appearance on the mouth mucosa, excessive salivation, and nasal discharge. In severe cases, the disease may lead to lameness and ulcers in the mouth and stomach.


Prevention of blue tongue deer disease involves preventing exposure to the disease. This infectious disease is caused by a virus called the bluetongue virus. The virus is not transmissible to humans, but can infect livestock and wildlife. Symptoms of this disease include fever, diarrhea, head swelling, and rapid death. The incubation period for the disease is five to ten days. Hunters should avoid shooting and eating infected deer.

There are two types of bluetongue deer disease. There are two types: Epizootic Hemorrhagic Disease and Bluetongue disease. Both are viral diseases and occur in large areas of the country. When infected, deer may show signs of weakness and fever.

In the past few years, there have been several outbreaks of the disease in New York, but these outbreaks are not as severe as those in other states. The virus is primarily transmitted by midges, so a deer infected with this disease is likely to die. Usually, an outbreak will end after the first hard frost, which will kill the midges that transmit the disease.

Infected deer may be more susceptible to the disease in high-density areas. However, the exact relationship between deer density and disease severity is not known. It may also depend on the number of immune deer in the area, the number of livestock nearby, and the abundance of midge vectors. In any case, dense deer herds are a good place for the disease to spread.

A deer with EHD may display symptoms of fever, swelling of the head, neck, tongue, and lips. It may also exhibit signs of lameness and seek a water source. A deer that has died from this disease is unlikely to spread to other animals, but it should be reported to your veterinarian so they can determine the cause of death.

The first step in preventing this disease is to identify and remove any deer that may be infected with it. If you find several dead deer, contact the MDIFW regional office to find out if the disease has spread. The disease usually kills the deer within 36 hours.
