Are children protected from infection or do they not fall ill after infection? If they are naturally immune, which is unlikely, we should understand why; otherwise, even if they do not show symptoms, it is important to know if they shed the virus. Obviously, the question about virus shedding of those being infected but asymptomatic leads to the crucial question of infectivity. Answers to these questions are especially pertinent as basis for decisions on school closure as a social distancing intervention, which can be hugely disruptive not only for students but also because of its knock-on effect for child care and parental duties. Very few children have been confirmed 2019-nCoV cases so far but that does not necessarily mean that they are less susceptible or that they could not be latent carriers. Serosurveys in affected locations could inform this, in addition to truly assessing the clinical severity spectrum.","tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"122","span":{"begin":225,"end":233},"obj":"Species"},{"id":"123","span":{"begin":828,"end":833},"obj":"Species"},{"id":"124","span":{"begin":869,"end":877},"obj":"Species"},{"id":"125","span":{"begin":898,"end":907},"obj":"Species"},{"id":"126","span":{"begin":192,"end":201},"obj":"Disease"},{"id":"127","span":{"begin":249,"end":258},"obj":"Disease"},{"id":"128","span":{"begin":289,"end":298},"obj":"Disease"},{"id":"129","span":{"begin":529,"end":537},"obj":"Disease"}],"attributes":[{"id":"A122","pred":"tao:has_database_id","subj":"122","obj":"Tax:9606"},{"id":"A123","pred":"tao:has_database_id","subj":"123","obj":"Tax:9606"},{"id":"A124","pred":"tao:has_database_id","subj":"124","obj":"Tax:9606"},{"id":"A125","pred":"tao:has_database_id","subj":"125","obj":"Tax:2697049"},{"id":"A126","pred":"tao:has_database_id","subj":"126","obj":"MESH:D007239"},{"id":"A127","pred":"tao:has_database_id","subj":"127","obj":"MESH:D007239"},{"id":"A128","pred":"tao:has_database_id","subj":"128","obj":"MESH:D007239"},{"id":"A129","pred":"tao:has_database_id","subj":"129","obj":"MESH:D007239"},{"subj":"122","pred":"source","obj":"LitCovid-PubTator"},{"subj":"123","pred":"source","obj":"LitCovid-PubTator"},{"subj":"124","pred":"source","obj":"LitCovid-PubTator"},{"subj":"125","pred":"source","obj":"LitCovid-PubTator"},{"subj":"126","pred":"source","obj":"LitCovid-PubTator"},{"subj":"127","pred":"source","obj":"LitCovid-PubTator"},{"subj":"128","pred":"source","obj":"LitCovid-PubTator"},{"subj":"129","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-PMC-OGER-BB","denotations":[{"id":"T61","span":{"begin":322,"end":328},"obj":"UBERON:0002405"},{"id":"T60","span":{"begin":462,"end":467},"obj":"NCBITaxon:10239"},{"id":"T59","span":{"begin":499,"end":504},"obj":"NCBITaxon:10239"},{"id":"T58","span":{"begin":898,"end":907},"obj":"SP_7"}],"attributes":[{"subj":"T61","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T60","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T59","pred":"source","obj":"LitCovid-PMC-OGER-BB"},{"subj":"T58","pred":"source","obj":"LitCovid-PMC-OGER-BB"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T36","span":{"begin":192,"end":201},"obj":"Disease"},{"id":"T37","span":{"begin":249,"end":258},"obj":"Disease"},{"id":"T38","span":{"begin":289,"end":298},"obj":"Disease"}],"attributes":[{"id":"A36","pred":"mondo_id","subj":"T36","obj":"http://purl.obolibrary.org/obo/MONDO_0005550"},{"id":"A37","pred":"mondo_id","subj":"T37","obj":"http://purl.obolibrary.org/obo/MONDO_0005550"},{"id":"A38","pred":"mondo_id","subj":"T38","obj":"http://purl.obolibrary.org/obo/MONDO_0005550"},{"subj":"T36","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T37","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T38","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T35","span":{"begin":12,"end":14},"obj":"http://purl.obolibrary.org/obo/CLO_0050510"},{"id":"T36","span":{"begin":25,"end":26},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T37","span":{"begin":462,"end":467},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T38","span":{"begin":499,"end":504},"obj":"http://purl.obolibrary.org/obo/NCBITaxon_10239"},{"id":"T39","span":{"begin":697,"end":698},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"}],"attributes":[{"subj":"T35","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T36","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T37","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T38","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T39","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-CHEBI","denotations":[{"id":"T1","span":{"begin":36,"end":41},"obj":"Chemical"},{"id":"T2","span":{"begin":214,"end":219},"obj":"Chemical"},{"id":"T3","span":{"begin":1020,"end":1028},"obj":"Chemical"}],"attributes":[{"id":"A1","pred":"chebi_id","subj":"T1","obj":"http://purl.obolibrary.org/obo/CHEBI_24433"},{"id":"A2","pred":"chebi_id","subj":"T2","obj":"http://purl.obolibrary.org/obo/CHEBI_24433"},{"id":"A3","pred":"chebi_id","subj":"T3","obj":"http://purl.obolibrary.org/obo/CHEBI_78059"},{"subj":"T1","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T2","pred":"source","obj":"LitCovid-PD-CHEBI"},{"subj":"T3","pred":"source","obj":"LitCovid-PD-CHEBI"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T38","span":{"begin":0,"end":220},"obj":"Sentence"},{"id":"T39","span":{"begin":221,"end":299},"obj":"Sentence"},{"id":"T40","span":{"begin":300,"end":468},"obj":"Sentence"},{"id":"T41","span":{"begin":469,"end":600},"obj":"Sentence"},{"id":"T42","span":{"begin":601,"end":859},"obj":"
