Mathematical Modelling for Infectious Disease Dynamics and Control in East Africa (MMIDD-EA)

Lead Research Organisation: University of Cambridge
Department Name: Veterinary Medicine

Abstract

Computer-based mathematical modelling of infectious diseases is an essential tool to understanding how diseases spread. They can also be extremely useful in designing effective control strategies and policies. The East Africa region is a hotspot for emerging and endemic diseases caused by bacteria and viruses, including those spread from animals to humans (known as zoonoses). Despite the potential for mathematical modelling to address public health challenges in the region and the availability of relatively cheap computing power and free programming platforms, these skills are rarely applied by academics and researchers in low and middle income countries. Instead modelling work is done by researchers from high income countries and often for diseases threatening global health such as epidemics caused by the Ebola virus. We aim to develop a network of East-African based mathematical modellers to build skills and capacity so that this work can be performed for priority infectious diseases in the region and by local researchers, who have a superior understanding of the social, economic, geographic and political context of infectious disease spread and control. To do this we will organise three activities. First, we will develop and run an intensive short-course in mathematical modelling of infectious disease dynamics for 20 people in Kenya. Applications will be sought from researchers based in East Africa with skills in mathematics and an interest in quantitative approaches to infectious disease dynamics and control in humans and animals. A competitive selection procedure will prioritise candidates with both institutional support and defined modelling projects relevant to the region to carry forward. The course will be based upon the well-established and highly regarded Mathematical Modelling of Infectious Disease Dynamics residential course supported by the Wellcome Trust, led Dr Andrew Conlan (University of Cambridge) and modified to be appropriate to the needs identified in East Africa. The course will have a strong emphasis on building practical skills using the free software R and Rstudio, and focussed on infectious diseases that are important in the region. Second, five fellowships will be awarded to course attendees to enable them to further develop their skills. Each fellow will be matched to a mentor from the University of Cambridge or the broader course faculty (drawn from across the UK and Africa) who will work with them to develop their skills and collaborate on a selected modelling projects. The fellows will have the opportunity to spend up to 3 months in Cambridge (or other UK Institute, as befits their project and development needs) as well as the opportunity to spend time at the University of Nairobi and interact with their cohort. Third, we will support the development of an East African infectious disease modelling network, by linking with other complementary initiatives in the region. This will increase the self-reliance of the cohort and help to sustain further capacity building.

Planned Impact

We expect that the ultimate impact of these capacity building activities will be to improve decision making in infectious disease control. We will enhance the capabilities of East African infectious disease modellers through training, mentorship, networking and seeding of mutually beneficial research collaborations. This cadre of modellers will be able to address important questions in infectious disease control in East Africa, ultimately addressing development challenges in the region.

Description As the COVID-19 pandemic has shown, mathematical models of infectious diseases are widely used to help us understand the patterns of infection in a population, to make predictions about future incidence and estimate the effect of different control measures to guide policy decisions. The aim of our project was to train a new group of mathematical modellers in East African countries. To do this, we built a partnership between the University of Cambridge (Department of Veterinary Medicine) and the University of Nairobi (Centre for Epidemiological Modelling & Analysis - CEMA). Because of the pandemic, our activities had to be moved online rather than held in person and were delayed. Nevertheless, we achieved our main objectives. There was a very high demand from participants across East Africa with 112 applications. We selected those individuals who we felt would benefit most from the training, while being mindful of the need to balance gender and include representatives from different countries. In July 2021, we held a 10 day intensive short course on mathematical modelling of infectious diseases, attended by 22 participants. The short course was highly rated by participants. From July through to December, we supported 13 fellows to conduct a specific mathematical modelling project. Their research topics covered a wide variety of infectious diseases, including COVID-19, tuberculosis, brucellosis, rift valley fever, human papillomavirus (HPV) and antimicrobial resistant infections. We held fortnightly meetings for the fellows to share their progress and arranged for additional mentorship where necessary. Some fellows found it challenging to find high-quality data to use in their models; this is an important learning point for us. Some fellows were able to present their research to Ministries of Health. The fellows rated their experience very highly. The award has enabled us to create a network of new infectious disease modellers across East Africa, from Kenya, Rwanda, Somalia, Sudan, Ethiopia and Uganda. We continue to meet every month for seminars on infectious disease modelling research. One Ugandan fellow was successful in obtaining a scholarship for a PhD at University of Cambridge and is currently undertaking his PhD fieldwork in Uganda.
Exploitation Route We have enhanced our learning about how to deliver training and support to enhance capacity in infectious disease modelling. This will certainly be taken forward by our own team, and has been shared with the Vaccine Impact Modelling Consortium (https://www.vaccineimpact.org/) who delivered a short course in September 2022.
