(2013). We rename the school term effect as the governmental action effect, since the former belongs to the latter. We also assume a period of zoonotic transmission during December 2019. We model the zoonotic transmission (denoted as F) as a stepwise function, which takes zero after the shutdown of Huanan seafood market (presumably). We then only model the sustained human-to-human transmission of COVID-19 after this date, along with the emigration of 5 million population before Wuhan was officially locked down (South China Morning Post, 2020). Thus, a compartmental model is formulated as follows:(1) S'=-β0SFN-β(t)SIN-μS,E'=β0SFN+β(t)SIN-(σ+μ)E,I'=σE-(γ+μ)I,R'=γI-μR,N'=-μN,D'=d   γI-λD,andC'=σE,where(2) β(t)=β0(1−α)1−DNκ.","divisions":[{"label":"label","span":{"begin":667,"end":670}},{"label":"label","span":{"begin":772,"end":775}}],"tracks":[{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T30","span":{"begin":464,"end":472},"obj":"Disease"},{"id":"T31","span":{"begin":685,"end":688},"obj":"Disease"},{"id":"T32","span":{"begin":705,"end":708},"obj":"Disease"}],"attributes":[{"id":"A30","pred":"mondo_id","subj":"T30","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"id":"A31","pred":"mondo_id","subj":"T31","obj":"http://purl.obolibrary.org/obo/MONDO_0024475"},{"id":"A32","pred":"mondo_id","subj":"T32","obj":"http://purl.obolibrary.org/obo/MONDO_0024475"},{"subj":"T30","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T31","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T32","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T25","span":{"begin":195,"end":196},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T26","span":{"begin":304,"end":305},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T27","span":{"begin":433,"end":438},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_9606"},{"id":"T28","span":{"begin":442,"end":447},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_9606"},{"id":"T29","span":{"begin":620,"end":621},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"}],"attributes":[{"subj":"T25","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T26","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T27","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T28","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T29","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T43","span":{"begin":0,"end":71},"obj":"Sentence"},{"id":"T44","span":{"begin":72,"end":179},"obj":"Sentence"},{"id":"T45","span":{"begin":180,"end":250},"obj":"Sentence"},{"id":"T46","span":{"begin":251,"end":399},"obj":"Sentence"},{"id":"T47","span":{"begin":400,"end":613},"obj":"Sentence"},{"id":"T48","span":{"begin":614,"end":794},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T43","pred":"source","obj":"LitCovid-sentences"},{"subj":"T44","pred":"source","obj":"LitCovid-sentences"},{"subj":"T45","pred":"source","obj":"LitCovid-sentences"},{"subj":"T46","pred":"source","obj":"LitCovid-sentences"},{"subj":"T47","pred":"source","obj":"LitCovid-sentences"},{"subj":"T48","pred":"source","obj":"LitCovid-sentences"}]},{"project":"LitCovid-PubTator","denotations":[{"id":"79","span":{"begin":433,"end":438},"obj":"Species"},{"id":"80","span":{"begin":442,"end":447},"obj":"Species"},{"id":"81","span":{"begin":207,"end":215},"obj":"Disease"},{"id":"82","span":{"begin":264,"end":272},"obj":"Disease"},{"id":"83","span":{"begin":464,"end":472},"obj":"Disease"}],"attributes":[{"id":"A79","pred":"tao:has_database_id","subj":"79","obj":"Tax:9606"},{"id":"A80","pred":"tao:has_database_id","subj":"80","obj":"Tax:9606"},{"id":"A81","pred":"tao:has_database_id","subj":"81","obj":"MESH:D015047"},{"id":"A82","pred":"tao:has_database_id","subj":"82","obj":"MESH:D015047"},{"id":"A83","pred":"tao:has_database_id","subj":"83","obj":"MESH:C000657245"},{"subj":"79","pred":"source","obj":"LitCovid-PubTator"},{"subj":"80","pred":"source","obj":"LitCovid-PubTator"},{"subj":"81","pred":"source","obj":"LitCovid-PubTator"},{"subj":"82","pred":"source","obj":"LitCovid-PubTator"},{"subj":"83","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_"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"LitCovid-PD-MONDO","color":"#eca693","default":true},{"id":"LitCovid-PD-CLO","color":"#9399ec"},{"id":"LitCovid-sentences","color":"#b3ec93"},{"id":"LitCovid-PubTator","color":"#ec93cd"}]}]}}
