However, efforts are hindered by negative SARS-CoV-2 test results for respiratory specimens and possible cross-reactivity with other coronaviruses among seropositive cases (2,3). Little is known about the value of various samples other than nasopharyngeal or oropharyngeal swab specimens in diagnosing COVID-19 and understanding the viral dynamics of SARS-CoV-2 in children. Virus RNA was persistently detected in rectal swab specimens in a previous study, although the infectiousness of the virus is unknown (4). We analyzed the viral RNA load kinetics of SARS-CoV-2 in various clinical specimens in children with COVID-19.","tracks":[{"project":"LitCovid-PD-FMA-UBERON","denotations":[{"id":"T8","span":{"begin":673,"end":676},"obj":"Body_part"},{"id":"T9","span":{"begin":828,"end":831},"obj":"Body_part"}],"attributes":[{"id":"A8","pred":"fma_id","subj":"T8","obj":"http://purl.org/sig/ont/fma/fma67095"},{"id":"A9","pred":"fma_id","subj":"T9","obj":"http://purl.org/sig/ont/fma/fma67095"},{"subj":"T8","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T9","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T7","span":{"begin":48,"end":56},"obj":"Disease"},{"id":"T8","span":{"begin":69,"end":116},"obj":"Disease"},{"id":"T9","span":{"begin":69,"end":102},"obj":"Disease"},{"id":"T10","span":{"begin":118,"end":126},"obj":"Disease"},{"id":"T11","span":{"begin":196,"end":205},"obj":"Disease"},{"id":"T12","span":{"begin":334,"end":342},"obj":"Disease"},{"id":"T13","span":{"begin":594,"end":602},"obj":"Disease"},{"id":"T14","span":{"begin":643,"end":651},"obj":"Disease"},{"id":"T15","span":{"begin":762,"end":776},"obj":"Disease"},{"id":"T16","span":{"begin":849,"end":857},"obj":"Disease"},{"id":"T17","span":{"begin":907,"end":915},"obj":"Disease"}],"attributes":[{"id":"A7","pred":"mondo_id","subj":"T7","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"id":"A8","pred":"mondo_id","subj":"T8","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"id":"A9","pred":"mondo_id","subj":"T9","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A10","pred":"mondo_id","subj":"T10","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A11","pred":"mondo_id","subj":"T11","obj":"http://purl.obolibrary.org/obo/MONDO_0005550"},{"id":"A12","pred":"mondo_id","subj":"T12","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A13","pred":"mondo_id","subj":"T13","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"id":"A14","pred":"mondo_id","subj":"T14","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A15","pred":"mondo_id","subj":"T15","obj":"http://purl.obolibrary.org/obo/MONDO_0005550"},{"id":"A16","pred":"mondo_id","subj":"T16","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A17","pred":"mondo_id","subj":"T17","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"subj":"T7","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T8","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T9","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T10","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T11","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T12","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T13","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T14","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T15","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T16","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T17","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T2","span":{"begin":231,"end":232},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T3","span":{"begin":345,"end":349},"obj":"http://purl.obolibrary.org/obo/UBERON_0000473"},{"id":"T4","span":{"begin":667,"end":672},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T5","span":{"begin":731,"end":732},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T6","span":{"begin":784,"end":789},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"}],"attributes":[{"subj":"T2","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T3","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T4","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T5","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T6","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PubTator","denotations":[{"id":"26","span":{"begin":69,"end":116},"obj":"Species"},{"id":"27","span":{"begin":118,"end":128},"obj":"Species"},{"id":"28","span":{"begin":133,"end":141},"obj":"Species"},{"id":"29","span":{"begin":334,"end":344},"obj":"Species"},{"id":"30","span":{"begin":425,"end":438},"obj":"Species"},{"id":"31","span":{"begin":643,"end":653},"obj":"Species"},{"id":"32","span":{"begin":657,"end":665},"obj":"Species"},{"id":"33","span":{"begin":849,"end":859},"obj":"Species"},{"id":"34","span":{"begin":893,"end":901},"obj":"Species"},{"id":"35","span":{"begin":27,"end":46},"obj":"Disease"},{"id":"36","span":{"begin":48,"end":56},"obj":"Disease"},{"id":"37","span":{"begin":196,"end":205},"obj":"Disease"},{"id":"38","span":{"begin":594,"end":602},"obj":"Disease"},{"id":"39","span":{"begin":907,"end":915},"obj":"Disease"}],"attributes":[{"id":"A26","pred":"tao:has_database_id","subj":"26","obj":"Tax:2697049"},{"id":"A27","pred":"tao:has_database_id","subj":"27","obj":"Tax:2697049"},{"id":"A28","pred":"tao:has_database_id","subj":"28","obj":"Tax:9606"},{"id":"A29","pred":"tao:has_database_id","subj":"29","obj":"Tax:2697049"},{"id":"A30","pred":"tao:has_database_id","subj":"30","obj":"Tax:11118"},{"id":"A31","pred":"tao:has_database_
