It was assumed that the virus can easily be detected in the upper respiratory tract at the stage of early infection. When the disease progressed, the virus was more likely to appear in the lower respiratory tract and other locations such as intestines and blood [9]. Thus, the virus may not be detected in throat swabs, especially for cases without expectoration. This may explain why some patients had negative RT-PCR for SARS-CoV-2 at initial presentation despite positive findings in chest CT, or positive RT-PCT and negative CT findings at initial presentation [10,11].","tracks":[{"project":"LitCovid-PD-FMA-UBERON","denotations":[{"id":"T31","span":{"begin":144,"end":167},"obj":"Body_part"},{"id":"T32","span":{"begin":273,"end":296},"obj":"Body_part"},{"id":"T33","span":{"begin":325,"end":335},"obj":"Body_part"},{"id":"T34","span":{"begin":340,"end":345},"obj":"Body_part"},{"id":"T35","span":{"begin":390,"end":396},"obj":"Body_part"},{"id":"T36","span":{"begin":571,"end":576},"obj":"Body_part"}],"attributes":[{"id":"A31","pred":"fma_id","subj":"T31","obj":"http://purl.org/sig/ont/fma/fma45661"},{"id":"A32","pred":"fma_id","subj":"T32","obj":"http://purl.org/sig/ont/fma/fma45662"},{"id":"A33","pred":"fma_id","subj":"T33","obj":"http://purl.org/sig/ont/fma/fma7199"},{"id":"A34","pred":"fma_id","subj":"T34","obj":"http://purl.org/sig/ont/fma/fma9670"},{"id":"A35","pred":"fma_id","subj":"T35","obj":"http://purl.org/sig/ont/fma/fma228738"},{"id":"A36","pred":"fma_id","subj":"T36","obj":"http://purl.org/sig/ont/fma/fma9576"},{"subj":"T31","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T32","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T33","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T34","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T35","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T36","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-UBERON","denotations":[{"id":"T31","span":{"begin":144,"end":167},"obj":"Body_part"},{"id":"T32","span":{"begin":150,"end":167},"obj":"Body_part"},{"id":"T33","span":{"begin":273,"end":296},"obj":"Body_part"},{"id":"T34","span":{"begin":279,"end":296},"obj":"Body_part"},{"id":"T35","span":{"begin":325,"end":335},"obj":"Body_part"},{"id":"T36","span":{"begin":340,"end":345},"obj":"Body_part"},{"id":"T37","span":{"begin":390,"end":396},"obj":"Body_part"},{"id":"T38","span":{"begin":571,"end":576},"obj":"Body_part"}],"attributes":[{"id":"A31","pred":"uberon_id","subj":"T31","obj":"http://purl.obolibrary.org/obo/UBERON_0001557"},{"id":"A32","pred":"uberon_id","subj":"T32","obj":"http://purl.obolibrary.org/obo/UBERON_0000065"},{"id":"A33","pred":"uberon_id","subj":"T33","obj":"http://purl.obolibrary.org/obo/UBERON_0001558"},{"id":"A34","pred":"uberon_id","subj":"T34","obj":"http://purl.obolibrary.org/obo/UBERON_0000065"},{"id":"A35","pred":"uberon_id","subj":"T35","obj":"http://purl.obolibrary.org/obo/UBERON_0000160"},{"id":"A36","pred":"uberon_id","subj":"T36","obj":"http://purl.obolibrary.org/obo/UBERON_0000178"},{"id":"A37","pred":"uberon_id","subj":"T37","obj":"http://purl.obolibrary.org/obo/UBERON_0000341"},{"id":"A38","pred":"uberon_id","subj":"T38","obj":"http://purl.obolibrary.org/obo/UBERON_0001443"},{"subj":"T31","pred":"source","obj":"LitCovid-PD-UBERON"},{"subj":"T32","pred":"source","obj":"LitCovid-PD-UBERON"},{"subj":"T33","pred":"source","obj":"LitCovid-PD-UBERON"},{"subj":"T34","pred":"source","obj":"LitCovid-PD-UBERON"},{"subj":"T35","pred":"source","obj":"LitCovid-PD-UBERON"},{"subj":"T36","pred":"source","obj":"LitCovid-PD-UBERON"},{"subj":"T37","pred":"source","obj":"LitCovid-PD-UBERON"},{"subj":"T38","pred":"source","obj":"LitCovid-PD-UBERON"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T28","span":{"begin":190,"end":199},"obj":"Disease"},{"id":"T29","span":{"begin":507,"end":515},"obj":"Disease"},{"id":"T30","span":{"begin":596,"end":599},"obj":"Disease"}],"attributes":[{"id":"A28","pred":"mondo_id","subj":"T28","obj":"http://purl.obolibrary.org/obo/MONDO_0005550"},{"id":"A29","pred":"mondo_id","subj":"T29","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A30","pred":"mondo_id","subj":"T30","obj":"http://purl.obolibrary.org/obo/MONDO_0008296"},{"id":"A31","pred":"mondo_id","subj":"T30","obj":"http://purl.obolibrary.org/obo/MONDO_0015104"},{"subj":"T28","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T29","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T30","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T75","span":{"begin":35,"end":36},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T76","span":{"begin":108,"end":113},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T77","span":{"begin":234,"end":239},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T78","span":{"begin":273,"end":296},"obj":"http://purl.obolibrary.org/obo/UBERON_0001558"},{"id":"T79","span":{"begin":325,"end":335},"obj":"http://purl.obolibrary.org/obo/UBERON_0000160"},{"id":"T80","span":{"begin":325,"end":335},"obj":"http://www.ebi.ac.uk/efo/EFO_0000834"},{"id":"T81","span":{"begin":340,"end":345},"obj":"http://purl.obolibrary.org/obo/UBERON_0000178"},{"id":"T82","span":{"begin":340,"end":345},"obj":"http://www.ebi.ac.uk/efo/EFO_0000296"},{"id":"T83","span":{"begin":361,"end":366},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T84","span":{"begin":571,"end":576},"obj":"http://www.ebi.ac.uk/efo/EFO_0000965"}],"attributes":[{"subj":"T75","pred"
