It has since been identified as a zoonotic coronavirus, similar to SARS coronavirus and MERS coronavirus and named COVID-19. As of 8 February 2020, 33 738 confirmed cases and 811 deaths have been reported in China.\nHere we review the basic reproduction number (R0) of the COVID-19 virus. R0 is an indication of the transmissibility of a virus, representing the average number of new infections generated by an infectious person in a totally naïve population. For R0 \u003e 1, the number infected is likely to increase, and for R0 \u003c 1, transmission is likely to die out. The basic reproduction number is a central concept in infectious disease epidemiology, indicating the risk of an infectious agent with respect to epidemic spread.","divisions":[{"label":"title","span":{"begin":0,"end":12}},{"label":"p","span":{"begin":13,"end":341}}],"tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"11","span":{"begin":170,"end":181},"obj":"Species"},{"id":"12","span":{"begin":194,"end":210},"obj":"Species"},{"id":"13","span":{"begin":215,"end":231},"obj":"Species"},{"id":"14","span":{"begin":89,"end":104},"obj":"Disease"},{"id":"15","span":{"begin":161,"end":169},"obj":"Disease"},{"id":"16","span":{"begin":242,"end":250},"obj":"Disease"},{"id":"17","span":{"begin":306,"end":312},"obj":"Disease"},{"id":"22","span":{"begin":399,"end":413},"obj":"Species"},{"id":"23","span":{"begin":510,"end":520},"obj":"Disease"},{"id":"24","span":{"begin":609,"end":617},"obj":"Disease"},{"id":"25","span":{"begin":746,"end":764},"obj":"Disease"}],"attributes":[{"id":"A11","pred":"tao:has_database_id","subj":"11","obj":"Tax:11118"},{"id":"A12","pred":"tao:has_database_id","subj":"12","obj":"Tax:694009"},{"id":"A13","pred":"tao:has_database_id","subj":"13","obj":"Tax:1335626"},{"id":"A14","pred":"tao:has_database_id","subj":"14","obj":"MESH:D011014"},{"id":"A15","pred":"tao:has_database_id","subj":"15","obj":"MESH:D015047"},{"id":"A16","pred":"tao:has_database_id","subj":"16","obj":"MESH:C000657245"},{"id":"A17","pred":"tao:has_database_id","subj":"17","obj":"MESH:D003643"},{"id":"A22","pred":"tao:has_database_id","subj":"22","obj":"Tax:2697049"},{"id":"A23","pred":"tao:has_database_id","subj":"23","obj":"MESH:D007239"},{"id":"A24","pred":"tao:has_database_id","subj":"24","obj":"MESH:D007239"},{"id":"A25","pred":"tao:has_database_id","subj":"25","obj":"MESH:D003141"},{"subj":"11","pred":"source","obj":"LitCovid-PubTator"},{"subj":"12","pred":"source","obj":"LitCovid-PubTator"},{"subj":"13","pred":"source","obj":"LitCovid-PubTator"},{"subj":"14","pred":"source","obj":"LitCovid-PubTator"},{"subj":"15","pred":"source","obj":"LitCovid-PubTator"},{"subj":"16","pred":"source","obj":"LitCovid-PubTator"},{"subj":"17","pred":"source","obj":"LitCovid-PubTator"},{"subj":"22","pred":"source","obj":"LitCovid-PubTator"},{"subj":"23","pred":"source","obj":"LitCovid-PubTator"},{"subj":"24","pred":"source","obj":"LitCovid-PubTator"},{"subj":"25","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-PMC-OGER-BB","denotations":[{"id":"T19","span":{"begin":82,"end":87},"obj":"NCBITaxon:10239"},{"id":"T18","span":{"begin":170,"end":181},"obj":"NCBITaxon:11118"},{"id":"T17","span":{"begin":194,"end":198},"obj":"SP_10"},{"id":"T16","span":{"begin":199,"end":210},"obj":"NCBITaxon:11118"},{"id":"T15","span":{"begin":215,"end":219},"obj":"SP_9"},{"id":"T14","span":{"begin":220,"end":231},"obj":"NCBITaxon:11118"},{"id":"T13","span":{"begin":242,"end":250},"obj":"SP_7"},{"id":"T12","span":{"begin":306,"end":312},"obj":"GO:0016265"},{"id":"T11","span":{"begin":367,"end":379},"obj":"GO:0000003"},{"id":"T10","span":{"begin":399,"end":407},"obj":"SP_7"},{"id":"T9","span":{"begin":408,"end":413},"obj":"NCBITaxon:10239"},{"id":"T8","span":{"begin":464,"end":469},"obj":"NCBITaxon:10239"},{"id":"T7","span":{"begin":548,"end":554},"obj":"NCBITaxon:9606"},{"id":"T6","span":{"begin":683,"end":686},"obj":"GO:0016265"},{"id":"T5","span":{"begin":702,"end":714},"obj":"GO:0000003"}],"attributes":[{"subj":"T19","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T18","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T17","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T16","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T15","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T14","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T13","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T12","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T11","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T10","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T9","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T8","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T7","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T6","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T5","pred":"source","obj":"LitCovid-PMC-OGER-BB"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T3","span":{"begin":81,"end":98},"obj":"Disease"},{"id":"T4","span":{"begin":89,"end":98},"obj":"Disease"},{"id":"T5","span":{"begin":194,"end":198},"obj":"Disease"},{"id":"T6","span":{"begin":242,"end":250},"obj":"Disease"},{"id":"T7","span":{"begin":399,"end":407},"obj":"Disease"},{"id":"T8","span":{"begin":510,"end":520},"obj":"Disease"},{"id":"T9","span":{"begin":537,"end":547},"obj":"Disease"},{"id":"T10","span":{"begin":746,"end":764},"obj":"Disease"},{"id":"T11","span":{"begin":805,"end":815}
