Animal Diseases


In April 2010, Miyazaki prefecture in Southwest Japan experienced an outbreak of foot-and-mouth disease, one of the most contagious animal diseases. Although the outbreak was successfully contained in just four months, by July 2010 there were 292 cases and 300,000 cows and pigs had been slaughtered. This resulted in an economic loss of about 2 billion US dollars.

In addition to the economic impact of the epidemic, the mental and psychosocial well-being of individuals and the community at large was also affected. For example, the sudden death of large numbers of animals caused considerable mental stress among farmers as well as the veterinarians and municipal government teams involved in the slaughter and disposal of infected cattle and pigs.

Restrictions on movement were imposed as part of efforts to prevent the disease from spreading; this led to stress-related symptoms among some residents, particularly the elderly. In addition, many farmers experienced depression and anxiety about the future following the loss of their livelihoods.

Recognizing the multiple impacts of the disease epidemic, a coordinated multisectoral approach was adopted, under the One Health concept, to tackle the disease as well as manage the mental health and psychological well-being of the residents of Miyazaki.

In a video titled Responding to an animal disease epidemic: Lessons from Miyazaki, various stakeholders who were involved in responding to the epidemic reflect on the usefulness of a One Health approach in helping to successfully respond to and overcome the challenges of the disease outbreak.

Featured in the video is Kohei Makita, an associate professor of veterinary epidemiology at Rakuno Gakuen University who is on a joint appointment at the International Livestock Research Institute (ILRI). Makita and colleagues had earlier published work on the collaborative response of veterinary and psychiatry experts to the 2010 foot-and-mouth disease outbreak.

The video was produced by the World Bank Tokyo Development Learning Center, the United Nations University International Institute for Global Health, the National Center for Neurology and Psychiatry, Japan and Rakuno Gakuen University.

The International Livestock Research Institute (ILRI) has published a discussion paper on a study carried out to identify the successes and challenges associated with the use of a Rift Valley fever decision support tool in Kenya.

The decision support tool was developed by various stakeholders from government and non-government sectors following the 2006-07 outbreak of Rift Valley fever in East Africa. It identifies events leading to the disease outbreak and matches them with interventions that could be implemented at each point.

The study involved three activities:

  • a review of literature to describe systems that could be used with the decision support tool and to identify how other frameworks have been used to support disease control policies
  • focus group discussions and key informant interviews with farmer groups, local and international organizations and decision-makers in the Department of Veterinary Services
  • a stakeholder workshop to validate the findings obtained and develop recommendations on ways to improve awareness and utilization of the framework

Rift Valley fever, a viral disease that is endemic in sub-Saharan Africa, Saudi Arabia and Yemen, causes abortion and stillbirth in livestock and can cause serious conditions such as haemorrhagic fever and encephalitis in humans.

Download a brief that illustrates how scientists at the International Livestock Research Institute (ILRI) are working to identify key drivers for Rift Valley fever occurrence and transmission, and develop decision support tools to guide responses at various stages of the epidemic cycle of the disease.

Developed after the last devastating Rift Valley fever outbreak in Kenya in 2006-07, these research outputs are designed to enable decision-makers to take timely, evidence-based decisions to prevent and control future epidemics and reduce their impacts.

In particular, the Government of Kenya has incorporated the decision support tool in its Rift Valley fever contingency plan and local governments in the country regularly use outputs from ILRI’s work to assess their level of preparedness.

‘By now, it seems we’ve heard everything there is to hear about the mysterious bloody disease called Ebola: heartbreaking tales of loss and heroism, news of ground-breaking science to find a cure, reports of panic and much misinformation.

‘But there are three simple, if unpalatable, truths that we aren’t hearing enough about.

‘First, this is not a particularly mysterious disease.

‘It’s one of many haemorrhagic fevers caused by well-researched RNA viruses, including Lassa, Crimean-Congo haemorrhagic, dengue (‘break bone’) and yellow (jungle) fevers. All of them can cause similar symptoms in humans: fever, increased tendency to bleed and often death.

Currently new diseases are emerging at the rate of one every four months and three out of four of these diseases jump species from other animals. Many of these diseases are associated with agriculture. Scientists from the International Livestock Research Institute (ILRI) led two systematic reviews of disease emergence and burden to help in prioritization. The poster below, prepared for the Tropentag 2014 conference, presents the key findings of the reviews.

Sustainable intensification?: Implications for the emergence of diseases

This week, ILRI staff are participating in the Tropentag 2014 International Conference in Prague, Czech Republic (17-19 September 2014). There is also a dedicated ILRI@40 side event on livestock-based options for sustainable food and nutritional security and healthy lives.  See all the posters.

The Rift Valley fever virus is a mosquito-borne pathogen that causes explosive outbreaks of severe human and livestock disease in Africa and Arabian Peninsula. The rapid evolution of outbreaks of Rift Valley fever generates exceptional challenges in its mitigation and control.

A decision-support tool for prevention and control of Rift Valley fever in the Greater Horn of Africa identifies a series of events that indicates increasing risk of an outbreak and matches interventions to each event.

This poster, prepared for the Tropentag 2014 conference, presents information from a study that assessed the effectiveness of targeted vaccination in mitigating the impacts of outbreaks of Rift Valley fever.

We are pleased to congratulate Tarni Cooper, a veterinary scientist at the International Livestock Research Institute (ILRI), on being named as one of five recipients of the 2014 Distinguished Young Alumni awards of the University of Queensland (UQ). The award will be presented at a ceremony scheduled for 2 October 2014.

The award recognises outstanding alumni aged 35 years or younger whose early accomplishments inspire and provide leadership to students and alumni. She was a UQ valedictorian in 2010 when she was awarded her Bachelor of Veterinary Science degree with honours and also won the Dr John Gibb Biosecurity Memorial Prize that year.

In 2013, Cooper worked with ILRI’s Food Safety and Zoonoses program as an Australian Youth Ambassador for Development and was part of a research team that worked in rural Tanzania on a project to assess the presence of a range of potential pathogens in smallholder dairy cattle. She studied the use of various communication approaches to obtain informed consent during research.

Two new papers on MERS coronavirus and camels in Eastern Africa have been published in the science journal Emerging Infectious Diseases.

Summary points

  • Studies find that camels in Egypt, Kenya, Somalia and Sudan have antibodies to the coronavirus that causes MERS.
  • The first study indicates that young camels are at greater risk of harbouring the virus than older camels.
  • We do not know if the infections in East African camels have led to, or could lead to, disease in people; this possibility should be investigated.
  • We do not know if or how much the East African camel virus is related to the one infecting camels and people in the Arabian Peninsula and Egypt; this possibility…

A recent paper that maps the global distributions of the world’s major livestock species has already been used to advance understanding of where surveillance efforts should be targeted to prevent the possible spread of a lethal bird flu virus now circulating in poultry populations in China, where it has killed 62 people. The original mapping work, led by Tim Robinson, of the International Livestock Research Institute (ILRI), and published at the end of May, was immediately put to practical use in locating large regions in South and Southeast Asia that would suit the new lethal virus. Ominously, unlike H5N1, a viral strain of bird flu that has killed millions of poultry and at least 359 humans since its first appearance in 1987, H7N9 does not cause severe illness in the chickens it infects, making it much more difficult to detect, and…
