Overview

Wildlife diseases are caused by the transfer of pathogens between humans and animals. Over 75% of emerging diseases (such as COVID-19) originate in wildlife. Their spread is exacerbated by deforestation, wildlife exploitation, development, and poor waste management, all of which increase wild animal-human proximity and the chance of wildlife disease spillover.

States are considering a variety of bills to protect against future wildlife diseases. Without action, wildlife diseases will continue to spread, and future pandemics could be even harder to control.

Key Facts

Approximately one-quarter of human deaths are caused by infectious disease and nearly 60% of infectious diseases are considered zoonotic. However, 75% of newly emerging diseases are zoonotic.

EcoHealth

Examples of zoonotic diseases include COVID-19, HIV, malaria, ebola, SARS, bird flu, swine flu, West Nile, and Lyme disease.

CDC

Zoonotic diseases are increasing because of population growth, exploitation of wildlife, development and destruction of natural areas, and climate change.

Fact Sheet
Wildlife Disease Fact Sheet
Wildlife
February 16, 2024

Wildlife, or “zoonotic” diseases, are caused by the transfer of pathogens between animals and humans. Over 75% of emerging diseases originate in wildlife. Their spread is exacerbated by deforestation, wildlife exploitation, development, and poor waste management, all of which increase wild animal-human proximity and the chance of wildlife disease spillover. The costs of wildlife diseases to public health are enormous, and tend to fall disproportionately on BIPOC communities, stemming from poor healthcare access and structural discrimination. If states do not take action, wildlife diseases will continue to spread, and future pandemics could be even harder to control. Experts identify the One Health approach – a recognition of the interconnections between the health of people, animals, and our shared environment – as one of the best ways to respond to the threat of zoonotic disease.

Fact Sheet
Chronic Wasting Disease Fact Sheet
Wildlife
July 27, 2021

Chronic Wasting Disease (CWD) is a fatal neurological disease that affects cervids (deer, elk, moose, and caribou). This wildlife disease has raised concern in regards to its implications for hunters who often come into direct contact with these animals, and for Indigenous and other communities that typically consume cervid meat. Economic impacts have also been reported, with a decline of Minnesota deer licenses purchased between 2017-2019 in regions affected by CWD.

Fact Sheet
Elephant Ivory and Rhino Horn Bans Fact Sheet
Wildlife
July 28, 2021

Illegal ivory and rhino horn trafficking is an escalating global issue. Elephants and rhinos may soon be driven to extinction by poaching. The demand for elephant ivory and rhino horn, driven by China, Japan, the Philippines, the United States and other countries, has created a massive international market that has detrimental economic, social and environmental impacts in Africa. Poaching is now a sophisticated international crime racket and a national security threat with terrorist organizations using profits to finance attacks. The U.S. Fish and Wildlife Service recently instituted a near ban on ivory and rhino import and domestic interstate trade. But the states must regulate in-state sales. Many states have enacted or introduced a ban on ivory and rhino horn trades in their jurisdictions.

Wildlife Disease and Environmental Justice

The impacts and mainstream conversation surrounding wildlife disease transmission are often rooted in injustice and inequity. Reducing the emergence of zoonotic disease requires a holistic approach that accounts for the human communities disproportionately impacted by these diseases.

Distribution of Disease Deaths

Zoonotic diseases cause millions of human deaths each year, and they are heavily concentrated in low- to middle-income nations, especially those with high rates of contact between livestock and humans. (nature.com)

Unjust Blame for Disease Sources

Whether it be the use of live animal markets or the consumption of meat from wild animals, there is a tendency to blame wildlife diseases solely on the actions of those in the place where a disease first emerges. In reality, a range of environmental factors – including deforestation and climate change – are driving the increased emergence of zoonotic disease. (healthpolicypartnership.com)

Impact on Foodways

Wildlife diseases negatively impact small-scale subsistence farming systems, as well as local cultural traditions, that are depended on by rural and Tribal communities. (nafws.org)
