The MRC Tropical Epidemiology Group (TEG) led by Professor Helen Weiss, is based within the Department of Infectious Disease Epidemiology. The Group was established in 1972 and now comprises 34 statisticians and epidemiologists with a research portfolio of over 30 grants.  We conduct studies on the epidemiology and control of major public health problems of developing countries, with a major focus on HIV, tuberculosis, malaria and neglected tropical disease, and a special emphasis on intervention studies. The Group’s research is largely based in Africa and Asia.

Below are a few recent examples of where our work has had a significant impact on health policy and practice:

  • Results from the group’s studies in Tanzania have helped the Tanzanian national HPV vaccination programme to plan and implement HPV vaccination delivery strategies in Tanzania.
  • The World Health Organisation has produced policy recommendations for the management of SMC, based on the review of evidence which included pivotal work performed by members of TEG.
  • Group members helped to develop a new standard treatment regimen for visceral leishmaniasis which was incorporated into national treatment guidelines in Ethiopia, Kenya, Sudan and Uganda.
  • The work of TEG has influenced the World Health Organisation’s new guidelines on antiretroviral therapy with specific reference to task shifting and decentralisation in Africa.

Group members also have an active role in international technical and policy advisory groups to ensure that results from our studies are used to influence global policy, governance and guidelines.

Fellowship Scheme MRC Tropical Epidemiology Group

About the scheme

We are particularly proud of our TEG Training Fellowship Scheme, launched in 2005, which forms a key part of TEG’s investment in capacity development strategy. The Scheme provides support for promising research students from Sub-Saharan Africa to undertake MSc training in Medical Statistics at LSHTM followed by a year working as a statistician at one of our partner centres in Africa. The fellow continues to receive mentoring, supervision and support for the duration of their fellowship from members of our Group.

The summer project, chosen by the fellow, often provides an introduction to the research topic to be pursued further during the placement year. During the placement year, the fellow is exposed to different aspects of research including study design, data management, analysis and reporting of findings. They are guided by local statisticians and researchers as well as relevant TEG members.

The Scheme has been well received and is now very competitive, with over 100 applications each year. The majority of our fellows are now either working in medical research posts at research institutions in Africa, or are engaged in PhD studies.

The MRC-funded Tropical Epidemiology Group (TEG) initiates epidemiological research and provides epidemiological and statistical expertise for research projects in resource-poor settings. The mission of the Group has remained the same over the past 40 years – to conduct research on the epidemiology and control of diseases of major public health importance in developing countries.  We focus primarily on statistics and epidemiology with an emphasis on conducting rigorously designed intervention studies, including i) randomised controlled trials (RCTs) to identify effective interventions against these diseases and (ii) research strategies to implement such interventions. Our expertise is constantly evolving and we have established expertise in mathematical modelling, data management, and public health. In addition we have good links with social scientists and health economists which adds a further dimension to our work.

The Group has an expanding research programme in malaria. In 2011-12, this ranged from trials of malaria vaccines, malaria vector control tools, seasonal malaria chemoprevention, delivery systems for effective treatment drugs and long-lasting insecticidal nets, to studies on the impact of insecticide resistance on malaria vector control, the evaluation of programmatic interventions, and the epidemiology of malaria elimination. We collaborate closely with scientists in the UK and malaria endemic countries, with international agencies and with national malaria control programmes and other local implementing partners.

HIV and other Sexually Transmitted Infections

HIV/AIDS prevention projects in Mozambique. Copyright Sarah Bandali, LSHTM

We are involved in a number of studies which seek to better understand the dynamics of the HIV epidemic and its drivers as well as various randomised trials to evaluate HIV prevention and treatment strategies. The main aim of the Group’s work on HIV research is to evaluate prevention and treatment strategies. We continue our long-standing collaborations with the MRC/UVRI Unit in Uganda and MITU/NIMR in Tanzania, for example through the cohort of women at high risk in Kampala, which highlight the need for interventions to treat sexually transmitted infections (STIs), and to address alcohol use disorders in these vulnerable populations. There is increasing emphasis on the need for combination HIV prevention strategies, and the role of treatment as prevention. Mathematical models have predicted that test-and-treat interventions, in which the entire community is encouraged to access voluntary HIV testing with immediate onset of antiretroviral therapy (ART) for those infected (irrespective of CD4 count) may lead to steep reductions in HIV incidence. TEG has secured a major grant for the PopART trial, a three-arm cluster RCT in Zambia and South Africa that will evaluate the effectiveness of offering household-based HIV testing and offering immediate ART to all those testing positive.

Sputum smear reading for the OFLOTUB project, Conakry, Guinea

The TB research conducted by the Group consists of a broad range of studies including large-scale trials of treatment strategies for patients co-infected with TB and HIV to reduce mortality, studies to assess how new TB diagnostics can improve outcomes among TB suspects and patients, and the effect of earlier initiation of antiretroviral therapy (ART) in HIV-positive individuals on the incidence and prevalence of TB. Through its role as the Biostatistics Core of the Bill and Melinda Gates Foundation-funded Consortium to Respond Effectively to the AIDS and TB Epidemics (CREATE) programme, TEG was pivotal to the recent successful completion of two major cluster RCTs of interventions to control TB in HIV endemic settings. Results of these trials, the ZAMSTAR and Thibela TB studies, were presented at international meetings in 2011 and 2012 and published in peer-reviewed journals. We presented the findings of the OFLOTUB study, a Phase III study of a TB treatment-shortening regimen for drug sensitive TB, at an international meeting in late 2013, which is currently being written up for publication.  The Group’s work on the RAFA project has been extended into 2014 and we hope to have initial results available in early 2015. The work of the Group continues to expand with a new 6-year cluster RCT  soon to start in Lima, Peru. This is a socioeconomic intervention aiming to reduce further TB and mortality in TB-affected households.

The Group has significant research activity on neglected tropical diseases, with ongoing research projects on trachoma, visceral leishmaniasis, helminth infections, and epilepsy. Several important studies were completed in 2011-12, including innovative trials of the management of trachomatous trichiasis in Ethiopia, a trial of short course combination treatment for visceral leishmaniasis, now incorporated into treatment guidelines for East Africa and completion of a 5-year follow-up of the Entebbe Mother and Baby Study, which found no association between helminth infections and their treatment on incidence of other infectious diseases and eczema.

Non-communicable Diseases and Mental Health

Late breakfast in Lilongwe, Milawi

Non-communicable diseases, including mental health disorders, are responsible for an increasing burden of disease in Africa and other low-resource settings. Our work focuses largely on defining the burden of these conditions and evaluating programmatic interventions such as task-shifting, to improve diagnosis and treatment.

Current studies that TEG are involved in include i) a programme of health systems research on the control of non-communicable diseases in Tanzania and Uganda, ii) collaboration with the Malawi Epidemiology and Intervention Research Unit (MEIRU) to examine the prevalence of, and risk factors for, hypertension, diabetes and hyperlipidaemia in rural and urban Malawi; and iii) a series of randomised controlled trials evaluating psychological interventions delivered by lay health workers in India and Pakistan.

One of the Group’s objectives is to develop novel study designs and statistical and epidemiological methods, to facilitate interventions against within out priority diseases. Our ideas are motivated by problems we have found on the ground, and facilitated by the many and varied datasets we have helped generate. The major activity is mathematical modelling of HIV/AIDS, malaria, TB and pneumococcal pneumonia. These studies are designed to supplement the empirical data and increase our understanding of the determinants of disease, explore the effects of alternative interventions in different population settings and raise future research hypotheses.

We publish methodological papers in three main areas:

1. Randomised trial and other study designs, including endpoint selection, with emphasis on parasitological and entomological outcomes.

2. Causal inference, which seeks to estimate the strengths of relationships based on models of dependence.

3. Survey design and behavioural measurement, motivated by studies of HIV and other STIs.
