Chronic Wasting Disease and How to Protect Yourself

Home » Health & Fitness » Chronic Wasting Disease and How to Protect Yourself

In this article, we will discuss the causes, symptoms, transmission, and impacts of chronic wasting disease (CWD). As well as the precautions that can be taken to prevent its spread.

Introduction

Cervids, such as deer, elk, and moose, are susceptible to the transmissible spongiform encephalopathy (TSE) known as chronic wasting disease (CWD). TSEs are a category of neurodegenerative illnesses that cause progressive brain wasting.

Chronic wasting disease (CWD) is a highly infectious and lethal illness that has rapidly spread across North America. Its causing widespread alarm among wildlife and public health experts.

In this article, we will discuss the causes, symptoms, transmission, and impacts of chronic wasting disease (CWD). As well as the precautions that can be taken to prevent its spread.

Understanding Chronic Wasting Disease

Chronic wasting disease (CWD) is a progressive, neurodegenerative disease that affects the central nervous system of the cervids. It is caused by abnormal proteins called prions that cause brain damage and eventually lead to death.

The disease is characterized by weight loss, behavioral changes, and loss of physical coordination.

Chronic wasting disease (CWD) was first identified in 1967 in captive mule deer in Colorado and has since spread to captive and wild populations across North America.

The disease is highly contagious and can be transmitted from infected animals to healthy animals through contact with bodily fluids, tissues, or contaminated environments.

Symptoms of Chronic Wasting Disease (CWD)

The symptoms of chronic wasting disease (CWD) usually develop gradually and may not be noticeable for several months or even years after infection. Some common signs of chronic wasting disease (CWD) include:

  • Weight loss and emaciation
  • Behavioral changes, such as increased thirst, decreased fear of humans, and abnormal behaviors
  • Loss of physical coordination and muscle control
  • Increased drooling and salivation
  • Stumbling and stumbling gait

It is important to note that these symptoms are also common in other diseases and conditions, so a definitive diagnosis of chronic wasting disease (CWD) can only be made through laboratory testing.

Transmission of Chronic Wasting Disease (CWD)

Chronic wasting disease (CWD) is highly contagious and can be transmitted through direct contact with bodily fluids, tissues, or contaminated environments. This includes contaminated soil, water, and feed.

Infected animals can shed the prions that cause chronic wasting disease (CWD) in saliva, urine, and feces, and these prions can persist in the environment for years.

This means that healthy animals can become infected by eating contaminated food or water or by coming into contact with contaminated soil or other surfaces.

Impacts of Chronic Wasting Disease

Chronic wasting disease has significant impacts on both wild and captive populations of cervids. In wild populations, chronic wasting disease (CWD) can lead to significant declines in population numbers and can affect the overall health and genetic diversity of the population.

In captive populations, chronic wasting disease (CWD) can spread rapidly and can result in the loss of significant numbers of animals. This can have significant economic impacts on the captive cervid industry, as well as potential impacts on public health if contaminated meat from infected animals is consumed.

Prevention Measures for Chronic Wasting Disease (CWD)

To prevent the spread of chronic wasting disease (CWD), it is important to take the following precautions:

  • Do not transport live cervids or carcasses of dead cervids across state lines, as this can spread the disease to new areas.
  • If you hunt or kill a cervid, do not remove the head, spinal cord, or other tissues that may contain the prions that cause chronic wasting disease (CWD). These parts should be left in the field or disposed of in accordance with state and local regulations.
  • If you are a farmer or manage a captive cervid herd, take steps to prevent contamination of feed and water sources, as well as limit contact with wild cervids.
  • If you are a hunter, take steps to prevent spreading chronic wasting disease (CWD) by properly cleaning and sanitizing all equipment. Including hunting gear and vehicles, that may have come into contact with infected animals.
  • If you suspect that an animal may be infected with chronic wasting disease (CWD), report it to local wildlife officials and do not consume meat from the animal.

Understanding of chronic wasting disease (CWD) with Ongoing Research and Monitoring

It is also important to support ongoing research and monitoring efforts to better understand chronic wasting disease (CWD) and to develop effective management strategies.

This includes continued investment in research to better understand the transmission and impacts of the disease.

As well as monitoring programs to track the spread of chronic wasting disease (CWD) in wild populations.

Educate the Public on Safe Hunting Practices to Stop chronic wasting disease CWD

Additionally, it is important to educate the public about chronic wasting disease (CWD) and the importance of taking precautions to prevent its spread.

This includes providing information on safe hunting practices, proper disposal of deer carcasses. And the importance of not transporting live cervids or carcasses across state lines.

Chronic wasting disease (CWD) is a serious threat to the health of cervid populations, and it is crucial that we take the necessary precautions to prevent its spread.

By working together, we can help to ensure the continued health and viability of our wildlife populations for generations to come.

Understand the Risks of Eating Infected Meat With Chronic Wasting Disease (CWD)

Moreover, it is also important to raise awareness about the potential risks associated with consuming meat from infected animals.

While there is currently no evidence of chronic wasting disease (CWD) transmission to humans, the Centers for Disease Control and Prevention (CDC) recommends not consuming meat from infected animals as a precautionary measure.

Strategies to Reduce chronic wasting disease (CWD): Wildlife Agencies and Surveillance Programs

Finally, it is essential to collaborate with local and state wildlife agencies to develop effective management strategies for chronic wasting disease (CWD).

This includes implementing effective surveillance and monitoring programs and measures to reduce the transmission of the disease among wild populations. Such as reducing the movement of live animals and providing supplementary feed to minimize interactions between wild and captive cervids.

Chronic wasting disease (CWD) is a complex and rapidly evolving issue that requires a comprehensive and collaborative approach to manage effectively.

By continuing to invest in research, monitoring, and education, we can help to ensure the long-term health of our cervid populations and the environments they call home.

No Cure for chronic wasting disease (CWD): Prevention is the Best Management – Help Research Interventions to Stop Progression

Moreover, it is also important to support efforts to develop vaccines and treatments for chronic wasting disease (CWD). Currently, there is no cure for the disease.

The most effective way to manage it is to prevent its spread. However, ongoing research is being conducted to develop interventions that can slow or stop the progression of chronic wasting disease (CWD) in infected animals.

This could potentially have a significant impact on the health and viability of cervid populations, and it is crucial that we support these efforts.

Responsible Hunting Practices: A Key Step in Reducing Chronic Wasting Disease CWD

In addition, it is important to encourage responsible hunting practices and to promote the proper disposal of deer carcasses.

This can help to reduce the spread of chronic wasting disease (CWD) and other diseases that can impact wildlife populations.

Hunters can play a key role in monitoring the health of wildlife populations and reporting any suspected cases of chronic wasting disease (CWD) to local wildlife officials.

Bottom Line

Chronic wasting disease is a highly contagious and fatal disease that affects cervids, including deer, elk, and moose. It is caused by abnormal proteins called prions and is characterized by weight loss, behavioral changes, and loss of physical coordination.

The disease has significant impacts on both wild and captive populations of cervids. It is important to take precautions to prevent its spread. By being informed and taking action, we can help to protect our wildlife and ensure the continued health of our cervid populations.
