As you may already know, infections related to pollution have consistently been one of the leading causes of mortality for children under-five (U5) in many peri-urban slums all over the world, including respiratory and gastrointestinal infections. However, addressing this issue has proven to be complex, as these infections are likely to be caused by a variety of factors. With that in mind, we created the Childhood Infection and Pollution (CHIP) Consortium. We aim to address the complexity of these infections by working directly with the community to identify and subsequently mitigate their consequences through co-designed behaviour change and slum upgrading interventions. CHIP could be defined as a One Health, technology-enabled citizen science approach to reducing the infection burden and antimicrobial resistance in U5s in peri-urban slums in low- and middle-income countries.

This project builds off the Participatory Approach for Nutrition in Children: Strengthening Health, Education, Environment and Engineering Linkage (PANChSHEEEL) project conducted by the co-investigators from University College London, Jawaharlal Nehru University and Save the Children India, who used a participatory research model to address infant feeding practices to optimise early childhood nutrition in rural Banswara. By working directly with community members, they were able to develop and implement a complex intervention to increase uptake of optimal feeding practices. 

Hence the objectives of the Childhood Infections and Pollution (CHIP) Consortium are to address health inequalities across peri-urban slums whilst aligning with local Non-governmental Organisation’s infection priority goals (e.g. Stop Diarrhoea Initiative) while further collaborating between different institutions, organisations, and individual researchers all around the globe. We believe CHIP will allow encouraging interdisciplinary research innovation and implementation towards addressing the 2030 Sustainable Development Goals for i) no poverty; ii) zero hunger; iii) good health and wellbeing; iv) clean water and sanitation; v) affordable and clean energy; vi) reduced inequalities and vii) sustainable city environments (goals 1, 2, 3, 6, 7, 10 and 11).

We would like to take this opportunity to extend our appreciation to all of the friends, partners, and funders of CHIP for their support and commitment. Working together, we focus on the exciting opportunities ahead.

The Childhood Infections and Pollution Consortium (CHIP) is a multi-country endeavour led by co-directors Prof. Monica Lakhanpaul and Dr. Logan Manikam. The aim of CHIP is to reduce the infection and antimicrobial resistance (AMR) burden in children under-five (U5) in slums globally by identifying and addressing One Health infection factors. We leverage technology-enabled Citizen Science and other collaborative research methodologies to do this, co-developing meaningful slum-upgrading and behavioural interventions with the communities we work within the process. 


CHIP is operationalised in 2 stages: Stage 1 (S1) involves community engagement work to understand the feasibility and acceptability of operationalising Stage 2 (S2) within the community. To date, S1 has been successfully deployed in India, Indonesia, and Chile. S2 is a panel study which collects biological and non-biological samples across One Health axes to identify causes of U5 infections and AMR in the community it is active within. S2 facilitates the co-creation of low-cost behaviour change and slum upgrading interventions within the local community. S2 will first be operationalised in Indonesia in Summer 2021.

Where CHIP

Currently Operates

CHIP is a truly global operation. The S1 has been rolled out in Chile, India, and Indonesia. In 2021, S1 will be operationalised in Turkey and Sierra Leone, while S2 is piloted in Indonesia.

CHIP Methodology is centred around 2 Core Principles: One Health and Citizen Science. 

Stage 1: Feasibility and Public Engagement Work

The aim of S1 is to foster collaboration within a target community and to gauge the feasibility of - an appetite for - S2. All S1 activities are conducted in partnership with a local implementation partner, usually an NGO that is well-known and respected within the target community.  S1 involves the following components:

  • Transect Walk: Mapping of the physical environment, to identify possible One Health infection pathways and to gain an understanding of the community structure. 

  • Social Mapping: With help from local residents and guided by the results of the transect walk, a detailed map of the physical and social structure of the community is created.

  • 1:1 Interviews with Caregivers and Community Members: In-depth interviews give insight into community behaviours and the acceptability of sample collection and disease surveillance within the community.

  • Stakeholder Analysis and Interviews: Identify any external factors which may influence S2 interventions and ascertain interest in public-private partnerships. 

  • Creative Arts: Used as a community engagement strategy, to facilitate 2-way knowledge exchange about infections, pollution, and AMR. Creative outputs from community members are used to drive public engagement with CHIP, through exhibiting their lived experience via communications activities.

A conceptual map of One Health factors generated from data collected in previous iterations of the CHIP S1 protocol is available here.

Stage 2: Intervention

The aim of S2 is to develop a low-cost behaviour change and slum upgrading interventions, which address One Health factors found to be associated with childhood infections and AMR. S2 will be conducted as a panel study to facilitate greater understanding of the One Health pathways that lead to U5 infections and AMR in the community. Technology-enabled Citizen Science methodologies are leveraged to co-produce the slum-upgrading and behaviour-change interventions needed to address these health risks; this is done alongside community members and policymakers alike. S2 will be piloted in Indonesia in Summer 2021. 

CHIP Methodology is operationalised in 2 Stages. 

A diagram detailing the 2 Stages of CHIP is available here 


The One Health concept acknowledges the interrelated nature of human, animal and environmental health and promotes an interdisciplinary and multi-sectoral approach when addressing health threats.


Also referred to as Participatory Research, the Citizen Science approach works with communities to participate in the research process in a meaningful way. CHIP aims to engage with the community from the outset, and community members are involved in formulating research aims, data collection, and resultant public health interventions.
