We explored the potential of combining backward contact tracing with more conventional forward contact tracing for control of COVID-19.
This page list all our work on control measures for Covid-19.
We simulated the arrival of travellers infected with SARS-CoV-2 from the EU and USA to the UK. We assessed the performance of various testing and screening policies in terms of reducing the number of travellers released while still infectious and the number of days they remain infectious.
We evaluated the effectiveness of the cordon sanitaire in Wuhan to delay or prevent outbreaks of COVID-19 in other major cities in mainland China.
Using flight data, prevalence estimates and incidence estimates combined, we calculate the ratio of expected imported cases and local incidence globally.
Simulated isolation, tracing and quarantine control strategies for SARS-CoV-2 in a real-world social network generated from high resolution GPS data.
Using reported data on COVID-19 cases and fatalities globally, we estimated the proportion of symptomatic cases that were reported in 210 countries and territories. We then use these estimates to attempt to reconstruct the pandemic.
We use a stochastic age-structured transmission model to explore a range of COVID-19 intervention scenarios in the UK, including the introduction of school closures, social distancing, shielding of elderly groups, self-isolation of symptomatic cases, and extreme "lockdown"-type restrictions.
Projected epidemics in LMIC with and without interventions
We consider expanding the social bubble of either all households or only single occupance households or households with young children. We assess how the implementation of these strategies during lockdown impacts on the risk for Covid-19 resugence.
We analyse social contact data from Kenyan informal settlements to estimate if COVID-19 control measures have affected disease transmission, and economic and food security
Combining novel setting-specific social contact data from over 40,000 individuals in the UK with a mathematical model of COVID transmission, we compare the potential effects of isolation, contact tracing and physical distancing measures on epidemic control.
Interactive dashboard of Facebook colocation data
We examined human movement on multiple geographic scales to provide a complete picture of the overall dynamics while drawing links to their public health implications.
We simulated potential response strategies to assess their effectiveness in three African countries: Niger, Nigeria, and Mauritius.
We evaluated the potential benefits of other respiratory infectious disease vaccines in the context of the COVID-19 pandemic.
To determine if interventions aimed at air travellers can delay establishment of a SARS-CoV-2 outbreak in a previously unaffected country with no shared border with China.
We present the first results of an ongoing survey (CoMix) to track social contact behaviour during the Covid-19 pandemic, and compare social mixing to patterns found in a previous survey.
We estimate the proportion of observed cases that may have been caused by during the pre-symptomatic period of the corresponding primary cases.
To assess the viability of isolation and contact tracing to control transmission from imported cases of 2019-nCoV.
We evaluated effectiveness of thermal passenger screening for 2019-nCoV infection at airport exit and entry to inform public health decision-making.
