Its value depends on the estimation method used, underlying assumptions of modeling, time period covered, geographic regions (with varying preparedness of health care systems), and factors considered in the models that affect disease transmissions (such as the behavior of the susceptible and infected population). Intuitively, it can be interpreted as measuring the expected number of new cases that are generated by one existing case. It is of interest to note that our estimates are within this range. Based on the results from model B in Tables 4 and 5, one case leads to 2.992 more cases in the same city in the next 14 days (1.876 if cities in Hubei province are excluded). In the second sub-sample (February 2–February 29), these numbers are reduced to 1.243 and 0.614, respectively, suggesting that factors such as public health measures and people’s behavior may play an important role in containing the transmission of COVID-19.","tracks":[{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T102","span":{"begin":82,"end":90},"obj":"Disease"},{"id":"T103","span":{"begin":1090,"end":1098},"obj":"Disease"}],"attributes":[{"id":"A102","pred":"mondo_id","subj":"T102","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"id":"A103","pred":"mondo_id","subj":"T103","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"subj":"T102","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T103","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T195","span":{"begin":698,"end":699},"obj":"http://purl.obolibrary.org/obo/CLO_0001021"}],"attributes":[{"subj":"T195","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-GO-BP","denotations":[{"id":"T5","span":{"begin":59,"end":71},"obj":"http://purl.obolibrary.org/obo/GO_0000003"},{"id":"T6","span":{"begin":422,"end":430},"obj":"http://purl.obolibrary.org/obo/GO_0007610"},{"id":"T7","span":{"begin":1020,"end":1028},"obj":"http://purl.obolibrary.org/obo/GO_0007610"}],"attributes":[{"subj":"T5","pred":"source","obj":"LitCovid-PD-GO-BP"},{"subj":"T6","pred":"source","obj":"LitCovid-PD-GO-BP"},{"subj":"T7","pred":"source","obj":"LitCovid-PD-GO-BP"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T397","span":{"begin":0,"end":153},"obj":"Sentence"},{"id":"T398","span":{"begin":154,"end":160},"obj":"Sentence"},{"id":"T399","span":{"begin":161,"end":475},"obj":"Sentence"},{"id":"T400","span":{"begin":476,"end":597},"obj":"Sentence"},{"id":"T401","span":{"begin":598,"end":665},"obj":"Sentence"},{"id":"T402","span":{"begin":666,"end":840},"obj":"Sentence"},{"id":"T403","span":{"begin":841,"end":1099},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T397","pred":"source","obj":"LitCovid-sentences"},{"subj":"T398","pred":"source","obj":"LitCovid-sentences"},{"subj":"T399","pred":"source","obj":"LitCovid-sentences"},{"subj":"T400","pred":"source","obj":"LitCovid-sentences"},{"subj":"T401","pred":"source","obj":"LitCovid-sentences"},{"subj":"T402","pred":"source","obj":"LitCovid-sentences"},{"subj":"T403","pred":"source","obj":"LitCovid-sentences"}]},{"project":"LitCovid-PubTator","denotations":[{"id":"248","span":{"begin":1011,"end":1017},"obj":"Species"},{"id":"249","span":{"begin":82,"end":90},"obj":"Disease"},{"id":"250","span":{"begin":454,"end":462},"obj":"Disease"},{"id":"251","span":{"begin":1090,"end":1098},"obj":"Disease"}],"attributes":[{"id":"A248","pred":"tao:has_database_id","subj":"248","obj":"Tax:9606"},{"id":"A249","pred":"tao:has_database_id","subj":"249","obj":"MESH:C000657245"},{"id":"A250","pred":"tao:has_database_id","subj":"250","obj":"MESH:D007239"},{"id":"A251","pred":"tao:has_database_id","subj":"251","obj":"MESH:C000657245"},{"subj":"248","pred":"source","obj":"LitCovid-PubTator"},{"subj":"249","pred":"source","obj":"LitCovid-PubTator"},{"subj":"250","pred":"source","obj":"LitCovid-PubTator"},{"subj":"251","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":"#939bec","default":true},{"id":"LitCovid-PD-CLO","color":"#b5ec93"},{"id":"LitCovid-PD-GO-BP","color":"#ec93cf"},{"id":"LitCovid-sentences","color":"#93e9ec"},{"id":"LitCovid-PubTator","color":"#ecd593"}]}]}}
