Thermal scanning, which can identify passengers with fever (high external body temperature), allows for passengers exhibiting symptoms of 2019-nCoV infection to be tested before they board a plane. Similarly, entry screening for flights originating in the most affected regions may be under consideration at airports in regions in and outside China. We estimate that the key goal of syndromic screening at airports - to prevent infected travellers from entering countries or regions with little or no ongoing transmission - is only achievable if the rate of asymptomatic infections that are transmissible is negligible, screening sensitivity is almost perfect, and the incubation period is short. Based on early data from Li et al. [8], 2019-nCoV appears to have a shorter incubation period than severe acute respiratory syndrome (SARS), and a higher rate of asymptomatic infections [11]. Under generally conservative assumptions on sensitivity, we find that 46 of 100 infected travellers will enter undetected.","tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"116","span":{"begin":45,"end":54},"obj":"Species"},{"id":"117","span":{"begin":908,"end":917},"obj":"Species"},{"id":"118","span":{"begin":224,"end":229},"obj":"Disease"},{"id":"119","span":{"begin":309,"end":328},"obj":"Disease"},{"id":"120","span":{"begin":599,"end":607},"obj":"Disease"},{"id":"121","span":{"begin":742,"end":752},"obj":"Disease"},{"id":"122","span":{"begin":974,"end":1000},"obj":"Disease"},{"id":"123","span":{"begin":1002,"end":1006},"obj":"Disease"},{"id":"124","span":{"begin":1043,"end":1053},"obj":"Disease"},{"id":"125","span":{"begin":1140,"end":1148},"obj":"Disease"}],"attributes":[{"id":"A116","pred":"tao:has_database_id","subj":"116","obj":"Tax:2697049"},{"id":"A117","pred":"tao:has_database_id","subj":"117","obj":"Tax:2697049"},{"id":"A118","pred":"tao:has_database_id","subj":"118","obj":"MESH:D005334"},{"id":"A119","pred":"tao:has_database_id","subj":"119","obj":"MESH:C000657245"},{"id":"A120","pred":"tao:has_database_id","subj":"120","obj":"MESH:D007239"},{"id":"A121","pred":"tao:has_database_id","subj":"121","obj":"MESH:D007239"},{"id":"A122","pred":"tao:has_database_id","subj":"122","obj":"MESH:D012120"},{"id":"A123","pred":"tao:has_database_id","subj":"123","obj":"MESH:D045169"},{"id":"A124","pred":"tao:has_database_id","subj":"124","obj":"MESH:D007239"},{"id":"A125","pred":"tao:has_database_id","subj":"125","obj":"MESH:D007239"},{"subj":"116","pred":"source","obj":"LitCovid-PubTator"},{"subj":"117","pred":"source","obj":"LitCovid-PubTator"},{"subj":"118","pred":"source","obj":"LitCovid-PubTator"},{"subj":"119","pred":"source","obj":"LitCovid-PubTator"},{"subj":"120","pred":"source","obj":"LitCovid-PubTator"},{"subj":"121","pred":"source","obj":"LitCovid-PubTator"},{"subj":"122","pred":"source","obj":"LitCovid-PubTator"},{"subj":"123","pred":"source","obj":"LitCovid-PubTator"},{"subj":"124","pred":"source","obj":"LitCovid-PubTator"},{"subj":"125","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-PD-FMA-UBERON","denotations":[{"id":"T2","span":{"begin":245,"end":249},"obj":"Body_part"}],"attributes":[{"id":"A2","pred":"fma_id","subj":"T2","obj":"http://purl.org/sig/ont/fma/fma256135"},{"subj":"T2","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T26","span":{"begin":309,"end":328},"obj":"Disease"},{"id":"T27","span":{"begin":319,"end":328},"obj":"Disease"},{"id":"T28","span":{"begin":742,"end":752},"obj":"Disease"},{"id":"T29","span":{"begin":967,"end":1000},"obj":"Disease"},{"id":"T30","span":{"begin":1002,"end":1006},"obj":"Disease"},{"id":"T31","span":{"begin":1043,"end":1053},"obj":"Disease"}],"attributes":[{"id":"A26","pred":"mondo_id","subj":"T26","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"id":"A27","pred":"mondo_id","subj":"T27","obj":"http://purl.obolibrary.org/obo/MONDO_0005550"},{"id":"A28","pred":"mondo_id","subj":"T28","obj":"http://purl.obolibrary.org/obo/MONDO_0005550"},{"id":"A29","pred":"mondo_id","subj":"T29","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A30","pred":"mondo_id","subj":"T30","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A31","pred":"mondo_id","subj":"T31","obj":"http://purl.obolibrary.org/obo/MONDO_0005550"},{"subj":"T26","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T27","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T28","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T29","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T30","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T31","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T24","span":{"begin":3,"end":4},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T25","span":{"begin":92,"end":95},"obj":"http://purl.obolibrary.org/obo/CLO_0051582"},{"id":"T26","span":{"begin":335,"end":341},"obj":"http://purl.obolibrary.org/obo/UBERON_0000473"},{"id":"T27","span":{"begin":360,"end":361},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T28","span":{"begin":893,"end":895},"obj":"http://purl.obolibrary.org/obo/CLO_0001022"},{"id":"T29","span":{"begin":893,"end":895},"obj":"http://purl.obolibrary.org/obo/CLO_0007314"},{"id":"T30","span":{"begin":934,"end":935},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T31","span":{"begin":1013,"end":1014},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T32","span":{"begin":1055,"end":1057},"obj":"http://purl.obolibrary.org/obo/CLO_0053733"}],"attributes":[{"subj":"T24","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T25","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T26","pred":"source","obj":"LitCovid-PD-CLO"
