Virus Watch

Virus Watch is a research study of COVID-19 led by the Public Health Data Science team University College London in conjunction with the NHS, Doctors of The World and the Race Equality Foundation.

This household study aims to identify how the virus spreads in our community and how to stop it. Virus Watch has generated a wide range of evidence to inform COVID policy and decision-making. We have collected over 1 billion data points resulting in diverse interdisciplinary publications in behavioural science, occupational health, geospatial informatics and housing policy.

A key international contribution was made by demonstrating the need for COVID booster vaccinations and highlighting key clinical groups at risk of infection after vaccination.

Migration and Health

We are part of the UCL Commission on Migration and Health. Migration is one of the most important public health issues facing the world today. International and internal migration is increasing, triggered by displacement of large numbers of people due to conflict, natural disasters, search for safety, and economic opportunities. A well considered and humane policy course offers extraordinary opportunities to make major gains in health and wellbeing. We are conducting the Million Migrant Study as part of our work in this area, which will create a population-based cohort study to describe the hospital-based healthcare and mortality outcomes of 1.5 million non-European Union (EU) migrants and refugees in England.

Act-Early

ActEarly is a City Collaboratory approach to early promotion of good health and wellbeing. The project aims to create City Collaboratory testbeds to support the identification, implementation and evaluation of upstream interventions within a whole system city setting. Prevention of physical and mental ill-health will come from the cumulative effect of multiple system-wide interventions. Rather than scatter these interventions across many settings and evaluate single outcomes, we will test their collective impact across multiple outcomes with the goal of achieving a tipping point for better health. Our focus is on early life (ActEarly) in recognition of childhood and adolescence being such critical periods for influencing lifelong health and wellbeing.

Asymptomatic SARS-CoV-2 infections in community settings

Symptomatic/Asymptomatic diagram

In this analysis we found that the asymptomatic proportion of SARS-CoV-2 infections is relatively low (11%) when estimated from methodologically-appropriate studies. We have been continuing to update this work by including updated papers at they are published are now finding a figure of around 20% asymptomatic.

COVID-19 and homelessness in England

Our model quantified how accommodation can mitigate the impact of the COVID-19 pandemic on the homeless population of England, and reduce the burden on acute hospitals.
