ILRI’s mission is
to improve food and nutritional security
and to reduce poverty in developing
countries through research for
efficient, safe and sustainable
use of livestock —
ensuring better lives through livestock.
CGIAR and ILRI mandates
Livestock contribute to all 17 of
the SDGs and directly to at least 8
of the goals.

3. 3
Why focus on livestock health?
 Animal health
o Animal diseases cost several billion dollars a year and represent a major
constraint to increasing productivity; many tropical diseases represent neglected
problems.
 Human health
o Most animal source food in developing countries is sold in wet markets and most
is unsafe; foodborne disease causes over 2 billion people to fall ill every year.
o Animal health products are used widely, often unwisely or are not available, e.g.
drugs, antimicrobials and vaccines. More antimicrobials are used in animals than
in humans.
 Ecosystem health
o One new disease emerges every four months: 75% of new human diseases
emerge from animals; many have a wildlife–livestock interface

4. Gender and socio-economics: incentives, value chains, impacts, livelihoods etc.

One Health
• Understanding the linkages
• Adding values:
• More knowledge
• Better health (human or animal)
• Economical benefits
CGIAR is uniquely positioned and actively promoting
One Health in low- and middle-income countries

6. Animal and Human Health program: Goal and activities
To manage effectively or eliminate livestock, zoonotic and foodborne diseases that matter to poor
people through generation and utilization of new knowledge, technologies and products
Herd health Food safety and
antimicrobial resistance
Zoonoses and emerging
infectious diseases
Vaccines and diagnostics
Program activities centre around two fundamental objectives:
1. To increase the productivity of tropical livestock through better health
2. To reduce the negative impacts of livestock and their products on human health and the environment

health and livestock
productivity
 A package of technologies,

Insights on disease priorities in Ethiopia
• Differences in disease priorities between
policymakers and farmers
o Parasites and respiratory diseases most important
to farmers
o Reproductive diseases neglected in the past
• Division of labour results in different zoonoses
risks for men and women
o Limited knowledge on zoonoses in general
o Low awareness of risky behaviour
More emphasis needed on production diseases

10. 10
• Integration of interventions at community level
• Strong community participation, with other interventions by
the CGIAR Research Program on Livestock
• Parasite control
• Vaccination for production diseases
• Clinical diagnosis and monitoring
• Responsible antimicrobial use
• Mobile app to facilitate herd health and
productivity data recording over time
• Synergies of animal welfare and agroforestry

11. Urban livestock keeping in Hanoi city, Vietnam: Systems and
vector-borne diseases
1. Knowledge, attitudes and practices
among urban inhabitants regarding
risks and benefits of urban agriculture,
and current knowledge on mosquito-
borne disease transmission
2. The distribution of mosquitoes and Flaviviruses
(dengue, Japanese encephalitis, and Zika virus)
present in urban mosquitoes and its relationship to
livestock keeping.
4. Intervention package
• On-site training
• Given fans with simple key messages
• Weekly reminders through text messages
 3. Risk factors of mosquito-
borne flavivirus by
investigating febrile patients
in a national hospital

12. Work on zoonoses and emerging diseases in Africa:
Early warning and forecasting
• Studies on Rift Valley fever, a
mosquito-borne viral zoonosis
mainly affecting cattle, sheep,
goats and camels
• Outputs
o Risk maps
o Improved understanding on drivers, e.g.
climate change variability
o Livestock vaccination strategies
o Influencing policy in Kenya and Uganda

13. Surveillance of influenza virus in live bird markets in Hanoi
and three highland border provinces in northern Vietnam
- Monthly collection of swabs, faeces, bioaerosol, poultry worker nasal wash samples in the live bird markets in three
border provinces: H7N, emerging infectious diseases, pigs and poultry
- Weekly collection of samples in the biggest live bird markets in Hanoi

Approach:
• Situational analyses of food safety
• Capacity building on risk-based approaches
• Proof of concept: participatory risk assessment
• Pilot testing interventions

17. Policy impact: translational research for interventions in
modernizing food system
• CGIAR/ILRI niche: risk assessment and policy/regulatory
analysis for fresh foods in domestic markets
• World Bank convenes overall support to government:
ILRI led technical work
• Upcoming projects based on World Bank report we led
will improve food safety for 20 million people in major
cities of Vietnam

18. COVID-19 response at ILRI
• One Health COVID-19 testing at ILRI for Kenya
by the BMZ-funded One Health Centre in
Africa
• Continue to produce evidence-based scientific
assessments (e.g. active surveillance)
• Policy options (e.g. raise awareness and
improve health governance)
• A One Health approach is the optimal method
for preventing and responding to pandemics

Partners:
CGIAR COVID-19 Hub
http://a4nh.cgiar.org/covidhub/
The CGIAR COVID-19 Hub provides a coordinated research response to the global pandemic
threatening health systems worldwide, along with posing serious risks to food security; local
businesses and national economies; and hard-fought progress by stakeholders at all levels towards
the Sustainable Development Goals.
Launched 23 June 2020, the hub focuses on the four
research pillars making up the core of CGIAR’s response to
COVID-19:
1. Food systems
2. One Health
3. Inclusive public programs
4. Policies and investments
CGIAR COVID-19 Hub will focus on four primary
work areas:
1. Addressing value chain fractures
2. Integrating a One Health approach to COVID-19
responses
3. Supporting country COVID-19 responses
4. Addressing food system fragility and building
back better

Health is a useful approach to address complex health issues.
3. ILRI’s Animal and Human Health program has a portfolio of product lines in zoonoses,
emerging infectious diseases, antimicrobial resistance, food safety and herd heath,
focusing on products with clients and a delivery system.
4. Collaborations with Korea are being developed including African swine fever research
and information and communication technology for animal health surveillance and
response, among others.
