Spreading zoo animal diseases: Has Al Ain Zoo developed an effective program to deal with the threat?

Abstract

Large collections of animals of diverse species found in zoos and animal parks present a considerable challenge to facility managers in developing and implementing programs to prevent and control the spread of animal diseases. One need to only think about the nightmare consequences of an illness that could decimate a population of animals in a public setting such as a zoo and, in a worst-case scenario, spread to staff, visitors and even the public at large. Biologists have clearly shown how certain types of animals can act as reservoirs for disease viruses, for example, chimpanzees harboring the simian immunodeficiency virus that mutated to HIV or chickens and ducks spreading avian influenza virus to poultry workers and then to the public. Thus, disease control in zoos is an issue of the utmost importance, and managers and operators neglect it at their peril. The reputation and indeed the very existence of an animal park rests in the hands of a dedicated group of managers, veterinarians and technical staff, as well as zoo workers who must strictly follow procedures to prevent and contain animal-borne diseases. This case study focuses on the work of one man in a large internationally known facility to develop, implement, test and evaluate an innovative program for animal disease control. So, what would you do if you were the director of a large metropolitan zoo and your staff veterinarian came to you and said that there was an outbreak of a serious viral disease among a group of animals? Could you have prevented the disease? How will you treat the sick animals and stop the disease from spreading? Is there a risk of the zoo staff contracting the disease from handling sick animals? What about zoo visitors? These are all questions that are addressed in this new and intriguing case study focused on managing animal diseases in the setting of a zoo or wildlife park. Mark Craig, Director of Life Sciences at the Al Ain Zoo in the United Arab Emirates, has plenty to say about the planning, science and management skills necessary to insure that a large population of diverse wild animals remains healthy and thriving. The Al Ain Zoo is the largest of its kind in the Middle East, and while he has been in charge of the animal welfare program for more than six years, there have been few incidents of disease and all have been contained. What can be learned from his effective strategies and leadership skills is clearly discussed and illustrated in this unique real-world case study.
