The number of active virus particles present in a place was considered the most important factor for determining the risk of infection [27]. Various transmission ways of SARS-CoV-2 transmission include airborne transmission caused by small droplets, and larger droplet transmission (droplets can survive up to several days on different surfaces) [54]. The term “viral load” will also be used to refer to the number of active virus particles present in a space. Virus particles live for different lengths of time, depending on a number of factors, the most significant one being surface material. Risk of infection for any particular IndoorGML cell space was modelled as the viral load within the space.","tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"190","span":{"begin":416,"end":426},"obj":"Species"},{"id":"191","span":{"begin":93,"end":101},"obj":"Disease"},{"id":"192","span":{"begin":371,"end":380},"obj":"Disease"},{"id":"193","span":{"begin":850,"end":859},"obj":"Disease"}],"attributes":[{"id":"A190","pred":"tao:has_database_id","subj":"190","obj":"Tax:2697049"},{"id":"A191","pred":"tao:has_database_id","subj":"191","obj":"MESH:C000657245"},{"id":"A192","pred":"tao:has_database_id","subj":"192","obj":"MESH:D007239"},{"id":"A193","pred":"tao:has_database_id","subj":"193","obj":"MESH:D007239"},{"subj":"190","pred":"source","obj":"LitCovid-PubTator"},{"subj":"191","pred":"source","obj":"LitCovid-PubTator"},{"subj":"192","pred":"source","obj":"LitCovid-PubTator"},{"subj":"193","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-sentences","denotations":[{"id":"T197","span":{"begin":0,"end":245},"obj":"Sentence"},{"id":"T198","span":{"begin":246,"end":386},"obj":"Sentence"},{"id":"T199","span":{"begin":387,"end":597},"obj":"Sentence"},{"id":"T200","span":{"begin":598,"end":706},"obj":"Sentence"},{"id":"T201","span":{"begin":707,"end":841},"obj":"Sentence"},{"id":"T202","span":{"begin":842,"end":948},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T197","pred":"source","obj":"LitCovid-sentences"},{"subj":"T198","pred":"source","obj":"LitCovid-sentences"},{"subj":"T199","pred":"source","obj":"LitCovid-sentences"},{"subj":"T200","pred":"source","obj":"LitCovid-sentences"},{"subj":"T201","pred":"source","obj":"LitCovid-sentences"},{"subj":"T202","pred":"source","obj":"LitCovid-sentences"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"LitCovid-PubTator","color":"#ecd693","default":true},{"id":"LitCovid-sentences","color":"#bc93ec"}]}]}}
