You’ll often hear of rabid dogs, bats, skunks, foxes, and raccoons; but rarely would you suspect your season harvest targets to be affected by the deadly disease. However, several cases around the country have, without a doubt answering the question, ‘can deer get rabies?’

Rabies is highly contagious and can affect all mammals. It causes the swelling of the brain, and is fatal if left untreated. Although rabid deer are rare, symptoms include loss of balance, lethargy, orifice discharge, and aggressiveness. Loss of fur on the head or alopecia is the definitive sign that an ungulate is infected.

Rhabdovirus of the Rhabdoviridae family is the nasty microbe that causes rabies, attacking the nervous system of mammals. Once the clinical signs are confirmed, this contagion is almost always deadly. Let’s dig in and find out for sure if and how deer can get rabies.

What Is Rabies, and Can Deer Get It?

The name rabies comes from Latin ‘to rage’, which fits how the victim hyperventilates, thrashes, and is aggressive. Another form of the disease has less sensational death throes. Characteristics include numbness, depression, apathy, coma, or paralysis.  After the initial symptoms, the viral ailment is incurable, proving 100% fatal.

Rabies is a devastatingly terrifying disease, a contagious viral infection affecting all mammalian or warm-blooded species. Be very careful whenever you contact a rabid animal. After infection, the disease can cause death within a short period without the proper medication. Rabies is more prevalent in smaller animals such as raccoons, feral cats, bats, skunks, foxes, and coyotes.

On average, seven to ten thousand animals contract rabies every year. But experts believe many cases aren’t identified before they die. Deer and humans catch rabies by coming into contact with the saliva or tissue of an infected animal. Raccoons have the highest disease incidences, almost half the national average. Varmint that gets infected possibly got bitten by that rabid critter.

How Is Rabies Transmitted, and How Can Deer Get It?

In the early 2000s till 2018, Mid-Atlantic state’s hunting grounds experienced a rabid raccoon epidemic. It drove this critter’s share of the national average close to 90%. Rabies is transmitted from one mammal to another, primarily through saliva. An array of infected animals started showing up across the range due to bites, including beavers, bears, and whitetail bucks.

Rabies microbes aren’t transmitted by blood, feces, or urine of an infected animal, and they don’t go airborne either. Deer will probably lick the bite wound from a raccoon and its salivary glands; the virus will pass into the brain and neurological system. This strain of the virus acts ten times faster than other types. It’s best to give deer that’s acting symptomatic a wide berth.     

The last stage of the disease involves shedding or passing the contagion from the brain back to the saliva of the infected deer. The virus paralyzes internal throat muscles, leading the animal to froth and foam gobs the liquid as they attempt to harass and attack anything in their way. 

During this period, rabies is highly contagious but can only transmit through the animal’s bite, saliva, or nervous system tissue. Paralysis follows a few days before the animal’s death.

What Are the Signs of Rabies in Deer?

Symptoms of progressed rabies are salivation, excessive aggression, and restlessness. It makes it easier to spread the infection during its last stage. Rabid deer will act agitated,  excessive drooling while snapping and biting at real or imaginary subjects. There’ll also be discharging heavily from their eyes and nose.

Deer with a rabies infection may appear timid or tame and unafraid of humans, but they’ll also be wobbling around and circling disorientated. While these are suspect signs, they could also be indicative of CWD or lead poisoning. So what are the telltale behavioral symptoms of rabies alone?

Although not strictly descriptive of deer, rabies will make a nocturnal animal such as a skunk, raccoon, or bat come out during the day. Deer that rarely venture into populated areas will loiter around the neighborhood seeking someone or something to attack. A usually timid Bambi that becomes actively aggressive while exhibiting drool and self-mutilation, coupled with alopecia or bare-headedness, is rabid.
