The main reason for flight contact tracing is raising alertness for possible exposure to uncommon infectious diseases, enabling early recognition and treatment of the disease and timely installation of control measures (e.g. SARS and viral hemorrhagic fevers). keywords: arrival; contact; days; details; flight; influenza; passenger cache: cord-000562-ocp6yodg.txt plain text: cord-000562-ocp6yodg.txt item: #2 of 63 id: cord-001071-bjx5td52 author: Vanhems, Philippe title: Estimating Potential Infection Transmission Routes in Hospital Wards Using Wearable Proximity Sensors date: 2013-09-11 words: 5047 flesch: 41 summary: The collected data can provide information on important aspects that impact the spreading patterns of infectious diseases, such as the strong heterogeneity of contact numbers and durations across individuals, the variability in the number of contacts during a day, and the fraction of repeated contacts across days.

With high isolation and quarantine efficacy, contact tracing could reduce overall transmission by >40%, which would allow for substantial loosening of physical distancing measures. keywords: contact; license; preprint; testing; tracing cache: cord-339898-ptb6dst8.txt plain text: cord-339898-ptb6dst8.txt item: #60 of 63 id: cord-340461-hebe5cjb author: Brooks-Pollock, E. title: Using social contact data to predict and compare the impact of social distancing policies with implications for school re-opening date: 2020-07-27 words: 3214 flesch: 47 summary: Tracing and isolating social contacts of symptomatic cases so they do not transmit onwards is beneficial but does not control transmission in isolation [14] . After the introduction of Test and Trace system in the UK only 20% of social contacts of cases were successfully traced and isolated within 48 hours, though this has substantially increased over time [16] . keywords: contacts; impact; number; reproduction; school; transmission cache: cord-340461-hebe5cjb.txt plain text: cord-340461-hebe5cjb.txt item: #61 of 63 id: cord-341639-a8ig607t author: Hellewell, Joel title: Feasibility of controlling 2019-nCoV outbreaks by isolation of cases and contacts date: 2020-02-11 words: 4597 flesch: 46 summary: Contact tracing and isolation may not contain outbreaks of 2019-nCoV unless very high levels of contact tracing are achieved. We determined conditions where case isolation, contact tracing, and preventing transmission by infected contacts would be sufficient to control a new 2019-nCoV outbreak in the absence of other control measures. keywords: cases; contact; control; isolation; onset; transmission cache: cord-341639-a8ig607t.txt plain text: cord-341639-a8ig607t.txt item: #62 of 63 id: cord-346576-gtkx1r4a author: Lapolla, Pierfrancesco title: Privacy versus safety in contact-tracing apps for coronavirus disease 2019 date: 2020-07-14 words: 680 flesch: 52 summary: 4 Currently, various different frameworks have been developed to build contact tracing, such as open frameworks (GA-PPTP, DP-3T, Blue Trace, TCN) or private and controlled (PEPP-PT). However, in order to be effective, contact tracing must be supported not only by solid technology, capable of minimising the risk of attacks, but also by a system offering safe communication with appropriate authorities. keywords: app; contact cache: cord-346576-gtkx1r4a.txt plain text: cord-346576-gtkx1r4a.txt item: #63 of 63 id: cord-347217-zxsm18og author: Bengio, Yoshua title: The need for privacy with public digital contact tracing during the COVID-19 pandemic date: 2020-06-02 words: 1528 flesch: 27 summary: key: cord-347217-zxsm18og authors: Bengio, Yoshua; Janda, Richard; Yu, Yun William; Ippolito, Daphne; Jarvie, Max; Pilat, Dan; Struck, Brooke; Krastev, Sekoul; Sharma, Abhinav title: The need for privacy with public digital contact tracing during the COVID-19 pandemic date: 2020-06-02 journal: Lancet Digit Health DOI: 10.1016/s2589-7500(20)30133-3 sha: doc_id: 347217 cord_uid: zxsm18og nan The need for privacy with public digital contact tracing during the COVID-19 pandemic Digital contact tracing applications represent a powerful yet controversial strategy to combat the COVID-19 pandemic. No identifiable information regarding digital contact trails or personal health information that an individual enters on the application should be shared with other application users or public, private, and governmental agencies • Individual geolocation data should not be stored on a central server and should pass through a rigourous obfuscation protocol to reduce their information content to the bare minimum required for epidemiological and machine-learning modelling • Pseudonymised data should be used to inform machine-learning models, and only these data should be stored centrally on a protected server • Only non-identifiable aggregated data should be shared with public health institutions • The source code of the application and the algorithms used should be made accessible for public scrutiny • keywords: application; contact; data; public cache: cord-347217-zxsm18og.txt plain text: cord-347217-zxsm18og.txt
