Our research response
The research work of the Unit is continuing, and Unit scientists are also exploring opportunities to contribute to national efforts, both in response to the COVID-19 pandemic and its broader public health consequences.
Several of our staff are now helping directly with the COVID-19 crisis, working in clinical, public health or lab testing settings, while members of our Global Public Health Research team are leading efforts to crowd-source the translation of WHO facts on Coronavirus into as many African languages as possible.
A major research undertaking is to plan the roll out of a digital platform for obtaining serial information on symptoms and signs of COVID-19 over the next year in the Fenland study with measurement of antibody status when this is available. The aim is to identify early markers of the transition from asymptomatic to symptomatic COVID-19 infection. Update on this here!
Our public health programmes are engaged nationally and internationally in determining the implications for diet and activity behaviours of the epidemic in terms of food security and the impact on physical activity of the social distancing restrictions.
Finally, members of our genetics programme have joined the COVID-19 host genetics initiative which aims to bring together the human genetics community to generate, share, and analyse data to learn about the genetic determinants of COVID-19 susceptibility, severity and outcomes.

Research helps NHS support people with diabetes during coronavirus – September 2020
MRC Epidemiology Unit Director Nick Wareham has contributed to recent research that is being used to help the NHS offer greater support to those with diabetes. The research, published in in two papers in Lancet Diabetes and Endocrinology shows that people living with diabetes face a significantly higher risk of dying with COVID-19. A third of deaths in England are associated with the condition. As a result of this research, the NHS in England has called on people with diabetes to access help available to them, including a new dedicated helpline and online tools to help manage the condition during the outbreak.
Vitamin D for COVID-19: a case to answer? – September 2020
In a comment article in the Lancet, Unit scientist Professor Nita Forouhi and Professor Adrian Martineau of the Blizard Institute discuss the available evidence for a role for Vitamin D in preventing or treating COVID -19 infection.
They note that current evidence is inconclusive and recommend population-based trials investigating vitamin D supplementation as a means of reducing the severity of COVID-19. In meantime they urge measures to ensure that people achieve recommended daily amounts of Vitamin D (10 micrograms per day for adults in the UK) saying this “might also reduce the impact of COVID-19 in populations where vitamin D deficiency is prevalent; there is nothing to lose from their implementation, and potentially much to gain.”

Unit launches study to monitor COVID-19 in 12,000 Cambridgeshire residents – July 2020
Participants in Cambridgeshire’s Fenland Study are being invited to join an innovative study that will use a home-administered blood sampling device – the Drawbridge Health OneDraw device – to find out how many have evidence in their blood of previous COVID-19 infection.
The primary aim of this study is to quantify the proportion of people who have had COVID-19 in the Fenland cohort, and participants will be tested several times over the duration of the study allow researchers to identify new as well as existing COVID-19 cases. Researchers will also be able to determine if those with COVID-19 antibodies at the start of the study continue to have positive antibody status over the study period, or if antibody levels decline over time.
The study will also investigate whether it is possible to identify the COVID-19 pre-symptomatic phase using measurement of signs and symptoms collected via a smartphone App developed by Huma. Participants will use a smartphone app to record measurements such as heart rate, heart rate variability, respiratory rate, blood oxygen, and temperature. Participants will also enter health information such as body weight and diet changes, medication and supplement use, their mental health and wellbeing, and COVID-19 symptoms and potential risk factors.
Earlier lockdown restrictions linked to greater reduction in new COVID-19 cases – July 2020
A BMJ paper by Dr Nazrul Islam and colleagues – including senior author Professor Martin White at the MRC Epidemiology Unit – examines the association between implementation of physical distancing interventions and new cases of COVID-19 in 149 countries and regions.
Their findings show that physical distancing measures, such as closing schools, workplaces, and public transport, restricting mass gatherings, and restrictions on people’s movement within countries or regions (‘lockdown’), were associated with an overall reduction of 13% in new COVID-19 cases in a study period of up to 30 days after implementation of the measures .
The data also shows that implementing physical distancing measures earlier was associated with a greater reduction in new cases, and that in combination with school and workplace closure, restriction on mass gatherings seemed to be a key component associated with a decrease in COVID-19 incidence.

Sentiment and opinion analysis of public space physical activity in Lagos during lockdown – June 2020
Research has started on a Cambridge Africa Alborada COVID emergency call award: Sentiment and opinion analysis of public space physical activity in Lagos during lockdown: a data-driven approach to developing context-aware public health messaging to reduce disease vulnerability and improve COVID-19 control.
This project is led by Tolu Oni from our Global Public Health Research programme, and is a collaboration with Associate Professor Taibat Lawanson at the University of Lagos Centre for housing and sustainable development and Associate Professor Camaren Peter at the Graduate School of Business and Centre for Analytics and Behavioural Change at the University of Cape Town.
This project aims to conduct opinion analyses of public space leisure physical activity to explore perceptions of government lockdown restrictions (and enforcement), and the impact of these lockdown measures on the perceptions, nature and frequency of appropriation of public space for activity in Lagos. Findings will inform development of context-aware public health messaging that safely encourages physical activity in the short term and health foresight interventions to reduce co-morbidity-associated vulnerability to future health emergencies long-term.

OneDraw feasibility study launches – June 2020
Social distancing measures and new ways of working mean that new methods of blood sample collection are urgently needed for Unit studies. In preparation for a large-scale surveillance study in the Fenland cohort to determine the prevalence of previous infection with COVID-19, a study has been launched to evaluate a self-applied blood collection using a device called OneDraw.
It is important that we obtain adequate blood samples from participants using the dried blood spot (DBS) method that can be standardised as far as possible to undertake the COVID-19 serological testing repeatedly over a 6-month period.

Analysis of NHS health records of 3.8 million adults yields estimate of COVID-19 mortality according to underlying conditions and age – May 2020
An analysis published by a team of scientists that includes Unit researcher Dr Claudia Langenberg and colleagues at UCL, University College London Hospitals NHS Foundation Trust, and Health Data Research UK, indicates that at least 20% of the UK population has a high-risk underlying condition for COVID-19 infection listed by Public Health England.
The authors have created a publicly accessible COVID -19 risk calculator showing how age, sex and underlying health conditions can affect mortality rates in different scenarios. They write that the analysis, which used NHS health records from 3.8 million adults in England, shows that the UK government must ensure that measures to ease the lockdown take into account this clinical vulnerability.

School closure and management practices during coronavirus outbreaks including COVID-19: a rapid systematic review – April 2020
Researchers including Dr Oliver Mytton undertook a systematic review of published and pre-published studies to identify what is known about the effectiveness of school closures and other school social distancing practices during coronavirus outbreaks They conclude that school closures have much less impact on the spread of these viruses than other social distancing interventions, and recommend that policy makers need to be aware of the equivocal evidence when considering school closures for COVID-19, and consider combinations of social distancing measures.
