One Health is an approach that calls on
policymakers and health practitioners to consider the inextricable link
between human, animal and environmental health when designing public
health systems, research and programmes. In recent
years, 75% of emerging infectious diseases have originated in animals
or animal products.
It is
believed that Ebola spread to a young boy in rural Guinea from an
infected animal, sparking an epidemic that infected more than 28,000
people, including in the capital cities of six West African
countries. By taking an integrated approach
to public health, communities and countries can identify outbreaks in
animals before they spread to humans.
The conference – hosted by the World Health Organization (WHO) Regional Office for Africa and the Economic Community of West African States (ECOWAS) Commission, in collaboration with other regional and international partners – is the strongest political commitment to One Health in West Africa to date. On Friday, 38 ministers from 16 countries in West Africa endorsed a communiqué, pledging their commitment to implement the One Health approach both within and across countries (see below). This is a critical step forward toward implementing the WHO’s Regional Strategy on Health Security and Emergencies 2016-2020, which was agreed upon at the 66th session of the WHO Regional Committee for Africa in Addis Ababa, Ethiopia, in August.
“Disease outbreaks and public health crises – many of
which began in animals – have taken lives and livelihoods, severely
impacted our industries and economies, and taken a serious toll on our
already-stretched public health workforces,”
said Dr Matshidiso Moeti, the World Health Organization Regional
Director for Africa. “With so much at stake, the world simply cannot
afford to take a crisis-by-crisis approach to health security. Strong
systems and coordinated efforts are needed – both within
and between countries – to detect, report and control the spread of
diseases that affect animals and humans.”
West Africa is currently tackling outbreaks of
several zoonotic diseases, such as avian influenza in poultry in
Cameroon and Nigeria and Rift Valley fever in Niger, as well as
vector-borne public health threats, such as the recent emergence
of the Zika virus strain from Brazil in Cabo Verde and Guinea-Bissau.
These diseases impact not only health, but also food security and
economic security. For example, the Ebola outbreak cost Guinea, Liberia
and Sierra Leone nearly US$600 million in lost
gross domestic product, and avian influenza has cost the region tens of
billions of dollars since 2013.
Additionally,
the overuse and misuse of antibiotics in animals and crops is resulting
in the emergence of antibiotic-resistant disease pathogens – which is
rendering common
infectious diseases and bacterial infections more difficult and
expensive to treat. The approach of incorporating human, animal and
environmental health helps to keep these medicines effective by more
carefully and diligently managing their use.
The
communiqué signed by ministers will help bolster the regional
coordination and strong systems that are needed to help prevent and stop
disease outbreaks. The agreement
also announced the creation of framework that will help countries work
together
across sectors and borders to ensure effective integration of human, animal and environmental health efforts.
Ultimately, this will provide the basis for countries
in West Africa to conduct joint preparedness and response planning at
the country and sub-regional levels, which will help manage outbreaks
before they become national and international
crises.
Specifically, Member States party to the agreement
have pledged to carry out national risk assessments and set up alert
mechanisms for both common and emerging disease outbreaks within their
territories. Governments will be tasked with integrating
laboratories for human and animal samples to improve the timely
diagnosis of
diseases and track the spread of drug-resistant pathogens at the national level—a crucial step in the fight against antimicrobial resistance (AMR).
Together, these commitments will generate renewed
momentum for West African countries to prioritise health security and
pandemic preparedness. Ultimately, this will help drive progress towards
existing commitments and initiatives, such as
WHO’s International Health Regulations (IHR), a legal tool that helps
to ensure countries are better equipped to prevent, report and respond
to public health risks that could cross borders and threaten people
worldwide.
