  • Social contact patterns during the early Covid-19 pandemic in Norway

    Open AccessLamprini Veneti, Bjarne Robberstad et al.ARTICLEBMC Public Health2024

    Social contacts declined significantly in the months following the March 2020 lockdown, aligning with implementation of stringent social distancing measures. These findings contribute valuable empirical information into the social behaviour in Norway during the early pandemic, which can be used to enhance policy-relevant models for addressing future crises when mitigation measures might be implemented

  • Impact of tiered measures on social contact and mixing patterns of in Italy during the second wave of Covid-19

    Open AccessMichele Tizzani, Alessandro De Gaetano et al.ARTICLEBMC Public Health2023

    The progressive restriction tiers implemented in Italy reduced the reproduction number, with stricter interventions associated with higher reductions. Readily collected contact data can inform the implementation of mitigation measures at the national level in epidemic emergencies to come

  • The influence of Covid-19 risk perception and vaccination status on the number of social contacts across Europe

    Open AccessJames Wambua, Neilshan Loedy et al.ARTICLEBMC Public Health2023

    Our multi-country study yields significant insights on the importance of risk perceptions and vaccination in behavioral changes during a pandemic emergency. The apparent increase in social contact behaviour following vaccination would require urgent intervention in the event of emergence of an immune escaping variant

  • Longitudinal social contact data analysis

    Open AccessNeilshan Loedy, Pietro Coletti et al.ARTICLEBMC Public Health2023

    CoMix data highlights the variability of contact patterns across age groups and time, revealing the mechanisms governing the spread/transmission of COVID-19/airborne diseases in the population. Although such longitudinal contact surveys are prone to the under-reporting due to participant fatigue and drop-out, we showed that these factors can be identified and corrected using NBI GAMLSS. This information can be used to improve the design of simila…

  • The impact of Covid-19 vaccination in prisons in England and Wales

    Open AccessCiara V McCarthy, Oscar O’Mara et al.ARTICLEBMC Public Health2022

    The impact of vaccination in prison settings was highly dependent on early and rapid vaccine delivery. If administered to both those living and working in prison prior to an outbreak occurring, vaccines could substantially reduce COVID-19-related morbidity and mortality in prison settings

  • The local burden of disease during the first wave of the Covid-19 epidemic in England

    Open AccessEmily Nightingale, Emily S Nightingale et al.ARTICLEBMC Public Health2022

    Limitations in testing capacity biased the observed trajectory of COVID-19 infections throughout the first wave. Basing inference on COVID-19-related mortality and higher-coverage testing later in the time period, we could explore the extent of this bias more explicitly. Evidence points towards substantial under-representation of initial growth and peak magnitude of infections nationally, to which different parts of the country contribute unequal…

  • Global, regional, and national estimates of the population at increased risk of severe Covid-19 due to underlying health conditions in 2020

    Open AccessAndrew Clark, Mark Jit et al.ARTICLEThe Lancet Global Health2020

    BACKGROUND: The risk of severe COVID-19 if an individual becomes infected is known to be higher in older individuals and those with underlying health conditions. Understanding the number of individuals at increased risk of severe COVID-19 and how this varies between countries should inform the design of possible strategies to shield or vaccinate those at highest risk. METHODS: We estimated the number of individuals at increased risk of severe dis…

  • Feasibility of controlling Covid-19 outbreaks by isolation of cases and contacts

    Open AccessJoel Hellewell, Sam Abbott et al.ARTICLEThe Lancet Global Health2020

    Background Isolation of cases and contact tracing is used to control outbreaks of infectious diseases, and has been used for coronavirus disease 2019 (COVID-19). Whether this strategy will achieve control depends on characteristics of both the pathogen and the response. Here we use a mathematical model to assess if isolation and contact tracing are able to control onwards transmission from imported cases of COVID-19. Methods We developed a stocha…

  • The effect of control strategies to reduce social mixing on outcomes of the Covid-19 epidemic in Wuhan, China

    Open AccessKiesha Prem, Yang Liu et al.ARTICLEThe Lancet Public Health2020

    BACKGROUND: In December, 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus, emerged in Wuhan, China. Since then, the city of Wuhan has taken unprecedented measures in response to the outbreak, including extended school and workplace closures. We aimed to estimate the effects of physical distancing measures on the progression of the COVID-19 epidemic, hoping to provide some insights for the rest of the world. …

  • Age-dependent effects in the transmission and control of Covid-19 epidemics

    Open AccessNicholas G Davies, Petra Klepac et al.ARTICLENature Medicine2020

    The COVID-19 pandemic has shown a markedly low proportion of cases among children1–4. Age disparities in observed cases could be explained by children having lower susceptibility to infection, lower propensity to show clinical symptoms or both. We evaluate these possibilities by fitting an age-structured mathematical model to epidemic data from China, Italy, Japan, Singapore, Canada and South Korea. We estimate that susceptibility to infection in…

  • Effects of non-pharmaceutical interventions on Covid-19 cases, deaths, and demand for hospital services in the UK

    Open AccessNicholas G Davies, Adam J Kucharski et al.ARTICLEThe Lancet Public Health2020

    Background Non-pharmaceutical interventions have been implemented to reduce transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the UK. Projecting the size of an unmitigated epidemic and the potential effect of different control measures has been crucial to support evidence-based policy making during the early stages of the epidemic. This study assesses the potential impact of different control measures for mitigating …

  • Effectiveness of isolation, testing, contact tracing, and physical distancing on reducing transmission of Sars-CoV-2 in different settings

    Open AccessAdam J Kucharski, Petra Klepac et al.ARTICLEThe Lancet Infectious Diseases2020

    BACKGROUND: The isolation of symptomatic cases and tracing of contacts has been used as an early COVID-19 containment measure in many countries, with additional physical distancing measures also introduced as outbreaks have grown. To maintain control of infection while also reducing disruption to populations, there is a need to understand what combination of measures-including novel digital tracing approaches and less intensive physical distancin…

  • The impact of Covid-19, associated behaviours and policies on the UK economy

    Open AccessMarcus Keogh-Brown, Henning Tarp Jensen et al.ARTICLESSM - Population Health2020

    We estimate the potential impact of COVID-19 on the United Kingdom economy, including direct disease effects, preventive public actions and associated policies. A sectoral, whole-economy macroeconomic model was linked to a population-wide epidemiological demographic model to assess the potential macroeconomic impact of COVID-19, together with policies to mitigate or suppress the pandemic by means of home quarantine, school closures, social distan…

  • Internet-based surveillance of Influenza-like-illness in the UK during the 2009 H1N1 influenza pandemic

    Open AccessNatasha L Tilston‐Lunel, Natasha L Tilston et al.ARTICLEBMC Public Health2010

    Internet-based monitoring of ILI can capture the trends in case numbers if appropriate weighting is used to correct for differential response. The overall level of incidence is, however, difficult to measure. Internet-based systems may be a useful adjunct to existing ILI surveillance systems as they capture cases that do not necessarily contact health care. However, further research is required before they can be used to accurately assess the abs…

  • Social Contacts and Mixing Patterns Relevant to the Spread of Infectious Diseases

    Open AccessJoël Mossong, Niel Hens et al.ARTICLEPLoS Medicine2008

    BACKGROUND: Mathematical modelling of infectious diseases transmitted by the respiratory or close-contact route (e.g., pandemic influenza) is increasingly being used to determine the impact of possible interventions. Although mixing patterns are known to be crucial determinants for model outcome, researchers often rely on a priori contact assumptions with little or no empirical basis. We conducted a population-based prospective survey of mixing p…

  • Estimating the cost-effectiveness of detecting cases of chronic hepatitis C infection on reception into prison

    Open AccessAndrew Sutton, Andrew J Sutton et al.ARTICLEBMC Public Health2006

    The work here demonstrates the importance of targeting those individuals that have ever engaged in illicit drug use for HCV testing in prisons, these individuals can then be targeted for future intervention measures such as treatment or monitored to prevent future transmission

  • Modelling the characteristics of the male injecting drug user population in England and Wales

    Open AccessAndrew Sutton, Andrew J Sutton et al.ARTICLEInternational Journal of Drug…2005

  • The average cost of measles cases and adverse events following vaccination in industrialised countries

    Open AccessHélène Carabin, W John Edmunds et al.ARTICLEBMC Public Health2002

    These average cost estimates could be combined with incidence estimates and costs of immunisation programmes to provide estimates of the cost of measles to industrialised countries. Such estimates could be used as a basis to estimate the potential economic gains of global measles eradication

  • The cost of integrating hepatitis B virus vaccine into national immunization programmes

    Open AccessW John Edmunds, W EdmundsARTICLEHealth Policy and Planning2000

    National programmes of hepatitis B virus (HBV) vaccination are recommended by the World Health Organization for all countries. Countries suffering the highest burden of HBV disease are those most needy of universal vaccination, but are frequently of very low income and resources for health care are scarce. The introduction of HBV vaccination would inevitably stretch these resources further even with support of donor agencies. Thus an assessment o…
