Doctors are required by law to notify the Ministry of Health of cases of COVID-19.7 Further, Singapore implemented enhanced surveillance on Jan 31, 2020, to test for COVID-19 among patients in intensive care units and people who died of unknown cause, all people with pneumonia in hospitals, and individuals with influenza-like illness in sentinel primary-care clinics. Hospital-based doctors also have permission to test patients who they view with suspicion for clinical or epidemiological reasons. A confirmed case of COVID-19 is defined as an individual with a respiratory sample positive for SARS-CoV-2, using a laboratory-based PCR test (appendix p 1). Phylogenetic analysis is done of available viral genomic sequences to ascertain genetic clustering.","tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"63","span":{"begin":100,"end":106},"obj":"Species"},{"id":"64","span":{"begin":333,"end":341},"obj":"Species"},{"id":"65","span":{"begin":370,"end":376},"obj":"Species"},{"id":"66","span":{"begin":408,"end":414},"obj":"Species"},{"id":"67","span":{"begin":574,"end":582},"obj":"Species"},{"id":"68","span":{"begin":749,"end":759},"obj":"Species"},{"id":"69","span":{"begin":127,"end":135},"obj":"Disease"},{"id":"70","span":{"begin":225,"end":233},"obj":"Disease"},{"id":"71","span":{"begin":318,"end":326},"obj":"Disease"},{"id":"72","span":{"begin":420,"end":429},"obj":"Disease"},{"id":"73","span":{"begin":673,"end":681},"obj":"Disease"}],"attributes":[{"id":"A63","pred":"tao:has_database_id","subj":"63","obj":"Tax:9606"},{"id":"A64","pred":"tao:has_database_id","subj":"64","obj":"Tax:9606"},{"id":"A65","pred":"tao:has_database_id","subj":"65","obj":"Tax:9606"},{"id":"A66","pred":"tao:has_database_id","subj":"66","obj":"Tax:9606"},{"id":"A67","pred":"tao:has_database_id","subj":"67","obj":"Tax:9606"},{"id":"A68","pred":"tao:has_database_id","subj":"68","obj":"Tax:2697049"},{"id":"A69","pred":"tao:has_database_id","subj":"69","obj":"MESH:C000657245"},{"id":"A70","pred":"tao:has_database_id","subj":"70","obj":"MESH:C000657245"},{"id":"A71","pred":"tao:has_database_id","subj":"71","obj":"MESH:C000657245"},{"id":"A72","pred":"tao:has_database_id","subj":"72","obj":"MESH:D011014"},{"id":"A73","pred":"tao:has_database_id","subj":"73","obj":"MESH:C000657245"},{"subj":"63","pred":"source","obj":"LitCovid-PubTator"},{"subj":"64","pred":"source","obj":"LitCovid-PubTator"},{"subj":"65","pred":"source","obj":"LitCovid-PubTator"},{"subj":"66","pred":"source","obj":"LitCovid-PubTator"},{"subj":"67","pred":"source","obj":"LitCovid-PubTator"},{"subj":"68","pred":"source","obj":"LitCovid-PubTator"},{"subj":"69","pred":"source","obj":"LitCovid-PubTator"},{"subj":"70","pred":"source","obj":"LitCovid-PubTator"},{"subj":"71","pred":"source","obj":"LitCovid-PubTator"},{"subj":"72","pred":"source","obj":"LitCovid-PubTator"},{"subj":"73","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":"T1","span":{"begin":137,"end":145},"obj":"Body_part"},{"id":"T2","span":{"begin":796,"end":804},"obj":"Body_part"}],"attributes":[{"id":"A1","pred":"fma_id","subj":"T1","obj":"http://purl.org/sig/ont/fma/fma14542"},{"id":"A2","pred":"fma_id","subj":"T2","obj":"http://purl.org/sig/ont/fma/fma14542"},{"subj":"T1","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T2","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T28","span":{"begin":127,"end":135},"obj":"Disease"},{"id":"T29","span":{"begin":318,"end":326},"obj":"Disease"},{"id":"T30","span":{"begin":420,"end":429},"obj":"Disease"},{"id":"T31","span":{"begin":465,"end":474},"obj":"Disease"},{"id":"T32","span":{"begin":673,"end":681},"obj":"Disease"},{"id":"T33","span":{"begin":749,"end":757},"obj":"Disease"}],"attributes":[{"id":"A28","pred":"mondo_id","subj":"T28","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"id":"A29","pred":"mondo_id","subj":"T29","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"id":"A30","pred":"mondo_id","subj":"T30","obj":"http://purl.obolibrary.org/obo/MONDO_0005249"},{"id":"A31","pred":"mondo_id","subj":"T31","obj":"http://purl.obolibrary.org/obo/MONDO_0005812"},{"id":"A32","pred":"mondo_id","subj":"T32","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"id":"A33","pred":"mondo_id","subj":"T33","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"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"},{"subj":"T32","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T33","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T17","span":{"begin":55,"end":58},"obj":"http://purl.obolibrary.org/obo/CLO_0051582"},{"id":"T18","span":{"begin":146,"end":149},"obj":"http://purl.obolibrary.org/obo/CLO_0008337"},{"id":"T19","span":{"begin":309,"end":313},"obj":"http://purl.obolibrary.org/obo/UBERON_0000473"},{"id":"T20","span":{"begin":569,"end":573},"obj":"http://purl.obolibrary.org/obo/UBERON_0000473"},{"id":"T21","span":{"begin":653,"end":654},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T22","span":{"begin":715,"end":716},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T23","span":{"begin":767,"end":768},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T24","span":{"begin":7
