Local rail (SkyTrain) station crowding data, provided by Metro Vancouver’s transportation authority TransLink, gives a proxy for reduction in public transport use. Overall daytime travel was reduced by 16% for the week of March 9, 64% for the week of March 16, and 73% for the week of March 23. Estimates on adhering to physical distancing are also available from a publicly available respondent-driven survey [20]. The survey found the rate of respondents stating that there was a serious threat of a coronavirus outbreak in Canada increased from 42% on March 5–6 to 88% on March 20–23. For individuals who stated there was a serious threat, 89% stated they were keeping personal distance compared to 66% for individuals who did not believe there was a serious threat. Mobile phone location data from BlueDot [39] suggested that the maximum and cumulative distance travelled from home fell by approximately 90%, the portion of mobile phone check-ins at home rose by over 10%, and the portion of devices for which every check-in was at home rose by 60%. These estimates are also consistent with Google mobility [21], Citymapper index [40], and Apple mobility data [41]. These are indirect reflections of the contact rate but are supportive of a dramatic change in contact patterns as reflected in our model. Furthermore, similar data are widely available for many jurisdictions. Our results provide a direct estimate of contact rates in conjunction with mobility data.","tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"94","span":{"begin":659,"end":670},"obj":"Species"},{"id":"95","span":{"begin":1301,"end":1306},"obj":"Species"}],"attributes":[{"id":"A94","pred":"tao:has_database_id","subj":"94","obj":"Tax:11118"},{"id":"A95","pred":"tao:has_database_id","subj":"95","obj":"Tax:3750"},{"subj":"94","pred":"source","obj":"LitCovid-PubTator"},{"subj":"95","pred":"source","obj":"LitCovid-PubTator"}],"namespaces":[{"prefix":"Tax","uri":"https://www.ncbi.nlm.nih.gov/taxonomy/"},{"prefix":"MESH","uri":"https://id.nlm.nih.gov/mesh/"},{"prefix":"Gene","uri":"https://www.ncbi.nlm.nih.gov/gene/"},{"prefix":"CVCL","uri":"https://web.expasy.org/cellosaurus/CVCL_"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T195","span":{"begin":0,"end":156},"obj":"Sentence"},{"id":"T196","span":{"begin":157,"end":320},"obj":"Sentence"},{"id":"T197","span":{"begin":321,"end":451},"obj":"Sentence"},{"id":"T198","span":{"begin":452,"end":572},"obj":"Sentence"},{"id":"T199","span":{"begin":573,"end":744},"obj":"Sentence"},{"id":"T200","span":{"begin":745,"end":926},"obj":"Sentence"},{"id":"T201","span":{"begin":927,"end":1210},"obj":"Sentence"},{"id":"T202","span":{"begin":1211,"end":1326},"obj":"Sentence"},{"id":"T203","span":{"begin":1327,"end":1464},"obj":"Sentence"},{"id":"T204","span":{"begin":1465,"end":1535},"obj":"Sentence"},{"id":"T205","span":{"begin":1536,"end":1625},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T195","pred":"source","obj":"LitCovid-sentences"},{"subj":"T196","pred":"source","obj":"LitCovid-sentences"},{"subj":"T197","pred":"source","obj":"LitCovid-sentences"},{"subj":"T198","pred":"source","obj":"LitCovid-sentences"},{"subj":"T199","pred":"source","obj":"LitCovid-sentences"},{"subj":"T200","pred":"source","obj":"LitCovid-sentences"},{"subj":"T201","pred":"source","obj":"LitCovid-sentences"},{"subj":"T202","pred":"source","obj":"LitCovid-sentences"},{"subj":"T203","pred":"source","obj":"LitCovid-sentences"},{"subj":"T204","pred":"source","obj":"LitCovid-sentences"},{"subj":"T205","pred":"source","obj":"LitCovid-sentences"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"LitCovid-PubTator","color":"#ecaf93","default":true},{"id":"LitCovid-sentences","color":"#9593ec"}]}]}}
