Wildlife disease
Wild animals, domestic animals and humans share a large and increasing number of infectious diseases, known as zoonoses.[1] The continued globalization of society, human population growth, and associated landscape change further increase the interactions between humans and other animals, thereby facilitating additional infectious disease emergence.[2][3] Contemporary diseases of zoonotic origin include SARS, Lyme disease and West Nile virus.[4]
Disease emergence and resurgence in populations of wild animals are considered an important topic for conservationists, as these diseases can affect the sustainability of affected populations and the long-term survival of some species.[5] Examples of such diseases include chytridiomycosis, in amphibians; chronic wasting disease, in deer; white-nose syndrome, in bats; and devil facial tumour disease in Tasmanian devils.[6]
Prevention
Culling
Disease outbreaks in wild animals are sometimes controlled by killing infected individuals to prevent transmission to domestic and economically important animals.[7][8] Animal rights advocates argue against culling, as they consider individual wild animals to be intrinsically valuable and believe that they have a right to live.[9]
Vaccination programs
Wild animal suffering, as a result of disease, has been drawn attention to by some authors,[10] who argue that we should alleviate this form of suffering through vaccination programs.[11][12] Such programs are also deemed beneficial for reducing the exposure of humans and domestic animals to disease and for species conservation.[13]
The oral rabies vaccine has been used successfully in multiple countries to control the spread of rabies among populations of wild animals and reduce human exposure.[14] Australia, the UK, Spain and New Zealand have all conducted successful vaccination programs to prevent Bovine Tuberculosis, by vaccinating badgers, possums and wild boar.[15]
In response to the COVID-19 pandemic, it has been proposed that, in the future, wild animals could be vaccinated against coronaviruses to relieve the suffering of the affected animals, prevent disease transmission and inform future vaccination efforts.[16]
