Zoonotic disease is an old, but persistent, vividly modern problem to humanity. Historically, zoonotic diseases such as plague, rabies, influenza, to name but a few, have caused huge damage to the public health around the world. In the modern era of the new century, we are facing more challenge of zoonotic diseases. Indeed, just during the past two decades, we have experienced two pandemics (H1N1, 2009; COVID-19, 2019-2020) and several major epidemics such as SARS (2002-2003), MERS (2012), Zika (2007, 2013-2014), Ebola (2014) and plague (2017). Besides, many other zoonotic diseases such as Lyme, Hanta fever, Dengue have irrupted frequently in many countries or regions.  

Zoonotic diseases are maladies shared by both human and animals (both wild and domestic). The diseases can be virus, bacterium or a host of many other parasites. Both human and animals can be natural reservoir of these pathogens, which circulate between people and animals. Some pathogens need to complete their life span in several animal hosts, or need ectoparasitic vectors (e.g. fleas, mites, ticks) to spread from host to host. Some other pathogens spread via air droplet, feces or soil (e.g. influenza, Hanta fever).

Coevolution may play a significant role in the origin of zoonotic diseases in humans and animals (Kaján et al 2019). By about 10,000 years ago, domestication of animals for pets or food or laboring significantly increased the probability of cross infections of zoonotic diseases, and promoted coevolution of humans, animals and pathogens. During the arm race between pathogen and hosts, emerging or reemerging contagious agent would appear and cause an epidemic or even a pandemic to humans (Morand et al. 1996).

An Article by Working Group on Zoonotic Diseases Published

An article by the Working Group on Zoonotic Diseases is published in Zoonoses Volume 2 recently. The article is titled as "The Animal Origin of Major Human Infectious Diseases: What Can Past Epidemics Teach Us About Preventing the Next Pandemic?".


Emerging infectious diseases are one of the greatest public health challenges. Approximately three-quarters of these diseases are of animal origin. These diseases include classical zoonoses maintained in humans only via transmission from other vertebrates (e.g., rabies) and those initiated by a successful one-off zoonotic event (host-switch) in conjunction with efficient human-to-human transmission (e.g., H1N1 influenza). Here, we provide a systematic review, in conjunction with a meta-analysis and spatial risk modeling, to identify the major characteristics of past epidemics of animal origin and predict areas with high future disease emergence risk. Countermeasures against future pandemics of animal origin must focus on several key mechanisms. First, the eco-epidemiological contexts favoring spillover events must be clearly establish. Second, pathogen surveillance must be scaled up, particularly in taxa and/or eco-geographic areas with high disease emergence risk. Third, successful spillover risk must be mitigated through proactive strategies to interrupt animal-to-human transmission chains. Fourth, to decrease epidemic potential and prevent epidemics from becoming pandemics, improved source identification and real-time spatial tracking of diseases are crucial. Finally, because pandemics do not respect international borders, enhancing international collaboration is critical to improving preparedness and response.

Mini-symposium on Zoonotic Disease and 12th International Symposium of Integrative Zoology (ISIZ)

IUBS and the International Society of Zoonotic Sciences (ISZS) organise a Virtual Mini-symposium on Zoonotic Disease and 12th International Symposium of Integrative Zoology (ISIZ)  on 26th April 2021.

The theme of this program is to promote integrative studies on zoonotic diseases among scientists of different disciplines, so as to reveal the transmission pattern and dynamic of key zoonotic diseases which are imposing a high threat to humans. Serial mini-symposia (held on 26 April and 27 September 2021) are a part of the activities for the ISZS/IUBS Zoonotic Diseases Working Group.

The program is free and open to all.

IUBS establishes a working group on Zoonotic Diseases

With the objectives to promote integrative studies on zoonotic diseases among scientists of different disciplines, so as to reveal the transmission pattern and dynamic of key zoonotic diseases which is imposing high threat to humans, to training young scientists and students in field of zoonotic diseases, and to provide advices or knowledge to governments and the public for disease prevention and control, IUBS announces the establishment of a working group on Zoonotic Diseases. The group is chaired by Dr Santiago Merino Rodriguez and Zhibin Zhang.

Increasingly, more and more studies show that humans are important factors in affecting the prevalence of zoonotic diseases (Loh et al. 2015) and zoonotic risk. Land use by humans for urbanization, agricultural use and road construction is an important driver of many zoonotic disease outbreaks (Patz et al. 2004). Due to habitat destruction which result in local decline of large animals but increase of small animals such as rodents and then zoonotic diseases (Dirzo et al 2014). Land use and defaunation frequently result in replacement of wild animals (e.g. rodents) with domestic animals, which increases the contact between pathogens and domestic animals or small animals, thus increasing the probability of contact of pathogens and people (Young et al. 2014). Notably, illegal hunting and trade of animals or animal products remain being an increasing clandestine activity that strongly facilitates disease transmission risks from animals to humans (Young et al. 2016).

Climate factors may also play a significant role in the prevalence of zoonotic diseases. Many studies have demonstrated that favorable climate would increase the food resources and then increase the abundance of animal hosts and then the zoonotic diseases (e.g. plague, Lymes, Hanta fever) (Stenseth et al 2006, Hjelle & Glass. 2000, Ostfeld et al 2006, Xu et al 2011). Besides, climate change will alter the distribution of animal hosts and, thus, alter disease risk at different climate zones. Seasonality-driven climate would cause cyclic migration of animals which attribute to seasonal epidemic of many diseases such as influenza (Olsen et al., 2006).

The understanding and the way such understanding may lead society to prepare and deal with future zoonotic disease outbreaks demand scientific collaborative research on a host of disciplines. Therefore, adopting an integrative, multi-disciplinary approach involving multiple life sciences such as zoology, ecology, epidemiology, molecular biology, climate change biology, environmental biology is necessary to inform the policy making realm. To this end, international entities become crucial in coordinating global efforts. Similarly, governments and academic institutions around the globe need to value the efforts undertaken by such bodies and strengthen them going forward. For example, under the support by IUBS, infectious diseases have been explored in the scientific program of Biological Consequences and Global Change (BCGC), mostly through modeling approaches. However, we insist, it is crucial that zoonotic diseases are investigated in a coordinated, integrative way beyond the evidently essential medical perspective, bringing on board the ecological perspective, that is, linking humans, animals, pathogens, ecosystems and global environmental change – including Anthropogenically driven climate and biodiversity change. In this direction, IUBS has established a working group and an international scientific program on zoonotic diseases by bringing scientists and experts from all over the world.
