Definitely, there are c(0)=c0 and limt→∞c(t)=cb with cb\u003cc0. This is basically to assume the contacts are decreasing and the change rate per contact is r1. This constant provides a measure of public health intervention improvement in terms of self-isolation of all including susceptible individuals in the period.","tracks":[{"project":"LitCovid-PD-CLO","denotations":[{"id":"T42","span":{"begin":46,"end":47},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T43","span":{"begin":279,"end":281},"obj":"http://purl.obolibrary.org/obo/CLO_0008697"},{"id":"T44","span":{"begin":279,"end":281},"obj":"http://purl.obolibrary.org/obo/CLO_0052381"},{"id":"T45","span":{"begin":489,"end":491},"obj":"http://purl.obolibrary.org/obo/CLO_0008697"},{"id":"T46","span":{"begin":489,"end":491},"obj":"http://purl.obolibrary.org/obo/CLO_0052381"},{"id":"T47","span":{"begin":516,"end":517},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"}],"attributes":[{"subj":"T42","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T43","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T44","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T45","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T46","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T47","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T41","span":{"begin":0,"end":337},"obj":"Sentence"},{"id":"T42","span":{"begin":338,"end":397},"obj":"Sentence"},{"id":"T43","span":{"begin":398,"end":492},"obj":"Sentence"},{"id":"T44","span":{"begin":493,"end":650},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T41","pred":"source","obj":"LitCovid-sentences"},{"subj":"T42","pred":"source","obj":"LitCovid-sentences"},{"subj":"T43","pred":"source","obj":"LitCovid-sentences"},{"subj":"T44","pred":"source","obj":"LitCovid-sentences"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"LitCovid-PD-CLO","color":"#93c4ec","default":true},{"id":"LitCovid-sentences","color":"#deec93"}]}]}}
