African One Health network launched to prevent disease

The prevention and management of antimicrobial resistance (AMR)—a major global health threat—and neglected tropical diseases (NTDs) remain a challenge, particularly in sub-Saharan Africa. To better combat antimicrobial resistance, a One Health approach is needed to identify the links between human, animal and environmental factors that contribute to the problem.

The African One Health Network for Disease Prevention (ADAPT) has adopted such an approach. It aims to create the conditions for improved, sustainable and locally led management of antimicrobial resistance and neglected tropical diseases in seven countries in sub-Saharan Africa, in close collaboration with national, local and regional stakeholders.

Dr. Ahmed Abd El Wahed from the Institute of Animal Hygiene and Public Veterinary Services at Leipzig University is coordinating the project. He describes the project in the journal Nature Medicine.

"The aim of our multidisciplinary and broad-based project is to establish antimicrobial stewardship in sub-Saharan Africa and to prevent the transmission of infectious diseases through a One Health approach," says Dr. Ahmed Abd El Wahed.

Research institutions from the seven countries involved in this network—Uganda, Senegal, Ghana, Nigeria, the Democratic Republic of Congo, Ethiopia and Sudan—will define and analyze a range of biological-medical and socio- and investigate how they affect human, animal and in sub-Saharan Africa.

Targeted involvement of policy-makers

The targeted involvement of local, regional and national stakeholders from the participating countries in the network over the entire project period (2023 to 2027) is intended to enhance their technical expertise and thus increase the efficiency of the network as a whole.

"We involve policy-makers and other key stakeholders in the ministries of health and other institutions in the network countries in our work. This is how we hope to achieve the project's objectives," explains Abd El Wahed.

This project is working on comprehensive work packages to increase antimicrobial stewardship capacity in sub-Saharan Africa, including:

  • Screening for antimicrobial resistance in humans, cattle and poultry
  • Creating capacity for on-demand diagnostics of and neglected using mobile tests for field use
  • Studying the possible changes in the incidence of AMR following the increased use of antimicrobials before, during and possibly after the COVID-19 pandemic in sub-Saharan Africa
  • Controlling , particularly AMR, by evaluating and improving existing hygiene practices at the human-animal-environmental interface
  • and building capacity for sustainable guidance on antimicrobial stewardship.

Drawing on lessons from the COVID-19 pandemic

"The COVID-19 pandemic has shown the of ignoring the value of comprehensive prevention approaches and instead prioritizing isolated and limited interventions," says Professor Uwe Truyen from Leipzig University, co-director of the project, adding that communication, cooperation and coordination between the human, animal and environmental systems are therefore essential to prevent the impact of communicable diseases, especially zoonotic diseases, and to combat and control these infections.

It is also important to consider human socio-cultural factors, which act as independent variables. Inequality and vulnerability in human populations are two such socio-cultural factors that can exacerbate negative health outcomes.

The COVID-19 pandemic in sub-Saharan Africa clearly demonstrated this, as countries there were unable to sufficiently recognize, evaluate and address these complex challenges from a One Health perspective. The ADAPT project aims to further develop the capacity to adapt to these challenges and to address weaknesses in the prevention of communicable diseases in sub-Saharan Africa.
