Here, we investigate the spread of COVID-19 and the effectiveness of contact tracing in a university population, using a data-driven ego-centric network model constructed with social contact data collected during 2020 and similar data collected in 2010. We find that during 2020, university staff and students consistently reported fewer social contacts than in 2010, however those contacts occurred more frequently and were of longer duration. We find that contact tracing in the presence of social distancing is less impactful than without social distancing. By combining multiple data sources, we show that University-aged populations are likely to develop asymptomatic COVID-19 infections. We find that asymptomatic index cases cannot be reliably discovered through contact tracing and consequently transmission in their social network is not significantly reduced through contact tracing. In summary, social distancing restrictions had a large impact on limiting COVID-19 outbreaks in universities; to reduce transmission further contact tracing should be used in conjunction with alternative interventions.","is_dataset_classified":null,"base_score":0.0,"endowment":0.0,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"37690279","pmcid":null,"openalex_id":null,"authors":[],"funders":[{"funder_name":"Medical Research Council","grant_id":"MC/PC/19067","title":null},{"funder_name":"Medical Research Council","grant_id":"MR/V038613/1","title":"COVID-19 Modelling Consortium: quantitative epidemiological predictions in response to an evolving pandemic"},{"funder_name":"Wellcome Trust","grant_id":"unidentified","title":"unidentified"},{"funder_name":"National Institute for Health Research Health Protection Research Unit","grant_id":"","title":null},{"funder_name":"National Institute for Health and Care Research","grant_id":"","title":null},{"funder_name":"University of Bristol","grant_id":"","title":null},{"funder_name":"Wellcome Trust","grant_id":"","title":null},{"funder_name":"UK Research and Innovation","grant_id":"","title":null}],"total_grants":8,"fwci":null,"citation_percentile":null,"influential_citations":0,"citation_trend":[],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://doi.org/10.1016/j.epidem.2023.100716","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S175543652300052X?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S175543652300052X?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doaj.org/article/a3e0468e69844d3bbd144867c1df3257","host_type":"repository"},{"url":"https://doi.org/10.1101/2021.11.10.21265739","host_type":""},{"url":"https://www.medrxiv.org/content/medrxiv/early/2021/11/14/2021.11.10.21265739.full.pdf","host_type":""},{"url":"https://pubmed.ncbi.nlm.nih.gov/37690279","host_type":""},{"url":"https://dx.doi.org/10.1101/2021.11.10.21265739","host_type":""},{"url":"https://doi.org/https://doi.org/10.1016/j.epidem.2023.100716","host_type":""}],"fields_of_study":["03 medical and health sciences","0302 clinical medicine"],"mesh_terms":["Humans","Contact Tracing","Disease Outbreaks","Universities","Aged","COVID-19","Physical Distancing"],"keywords":["Survey","Infectious disease","epidemic","Contact tracing","Asymptomatic","Social Contact","330","Universities","Physical Distancing","Infectious and parasitic diseases","RC109-216","/dk/atira/pure/core/keywords/engineering_mathematics_research_group","Disease Outbreaks","Humans","Aged","name=Engineering Mathematics Research Group","COVID-19"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-27T15:18:16.371864Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
