Dr Eve Worrall

Health Economist and Senior Programme Manager

Eve has a background in economics (BA Hons. Economics, University of Liverpool, 1997) and a PhD on the economic benefits of climate based malaria early warning systems and the cost effectiveness of indoor residual spraying (IRS) for malaria control (LSTM, 2001). After her PhD she was a research fellow in the Economics of Malaria at the London School of Hygiene where she worked on various projects including extensive work on insecticide treated net (ITN) delivery in Tanzania. Eve then spent a year working as an adviser in a charity which aimed to improve philanthropic giving before joining LATH, the consultancy company of LSTM. Eve worked at LATH for five years as a technical advisor, consultant and project manager. The portfolio of projects she worked on at LATH included costing the health sector strategic plan for Mozambique, designing the five year strategy, annual work plan and overall performance monitoring framework for GAVI (Global Alliance on Vaccines and Immunisations) as well as costing larval source management activities for malaria control.

Eve is an expert in the economic evaluation of vector control interventions including insecticide treated nets, larval source management and indoor residual spraying. She is also working on evaluating novel vector control interventions (eaves tubes and spatial repellents) and has a strong interest in analysing the policy making process. She leads the Economics Work Package on a Wellcome Trust Collaborative Award ‘Malaria in Insecticide Resistant Africa (MiRA)’. MiRA’s aim is to understand why malaria is persisting in some high burden countries, despite widespread coverage of insecticide treated nets (ITNs) and adoption of WHO guidelines on detection and treatment of the disease. The project is measuring malaria risk factors, quantifying host seeking and resting behaviour of malaria vectors, insecticide resistance and recording actual net usage and treatment and prevention seeking behaviours at community level. Data is being used to update transmission models of malaria enabling us to estimate the impact of ITNs in settings that now typify much of the high malaria burden regions of Africa. The Economics Work Package  will estimate the most cost effective and affordable package of malaria prevention tools to reduce the incidence of malaria for Burkina Faso, and assess their affordability. Working with colleagues from Burkina Faso, we are collecting data to understand the cost burden from both the provider and societal perspective and using this to build a health system cost model and assess finances available for malaria control. Cost data from past and current interventions and outputs from the mathematical model will be combined to estimate the cost effectiveness of potential malaria control intervention package in Burkina Faso and assess their affordability and impact.

Eve also co-leads a Work Package in the Partnership for Increasing the Impact of Vector Control (PIIVeC) . PIIVeC, funded by RCUK’s Global Challenges Research Fund, aims to develop evidence-based strategies for the control of vector-borne disease in Africa and increase the utilization of this evidence in national decision-making, improve integration between disease-specific programmes, strengthen the resilience of African nations to respond to outbreaks of vector-borne disease and increase the leadership role of African scientists and vector biologists in global policy making on vector-borne disease. PIIVeC is led by LSTM in partnership with research institutes, NGOs and national control programmes in Burkina Faso, Cameroon and Malawi, and global policy making bodies. Work Package is co-led by Eve and Dr Eliya Zulu from AFIDEP and will use evidence synthesis and policy analysis to accelerate research uptake as well as work with other Work Packages to strengthen linkages between vector control research and policy at global and national level. 

Eve successfully managed the €12million EU funded AvecNet project and provides Senior level Programme Management support to Professor Hilary Ranson.
