Common imaging findings of influenza virus–associated pneumonia include GGO, consolidation, and a combination of both. Pleural effusion, if present, is usually minimal, and lymphadenopathy is rare [14, 15]. Organizing pneumonia has also been reported [16]. There are recent publications that have suggested that CT findings of COVID-19 are similar to the organizing pneumonia (OP) pattern observed from post viral or atypical infections and other etiologies [17]. Despite a study discussing the nonspecific nature of COVID-19 pneumonia [18], a recent publication suggests that radiologists are able to differentiate COVID-19 from other viral pneumonia on CT [5, 6, 18, 19]. Laboratory testing for the novel coronavirus is time-consuming, and there are reports of shortage of test kits in some locations [20]. As we learned increasingly, initial laboratory tests for coronavirus can be falsely negative [20]. Therefore, the presence of suspicious CT findings in patients, correlated with a number of days after symptom onset, should prompt repeat laboratory testing and consideration of respiratory isolation in patients with appropriate travel and exposure history.","tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"388","span":{"begin":122,"end":137},"obj":"Species"},{"id":"389","span":{"begin":796,"end":813},"obj":"Species"},{"id":"390","span":{"begin":961,"end":972},"obj":"Species"},{"id":"391","span":{"begin":1056,"end":1064},"obj":"Species"},{"id":"392","span":{"begin":1206,"end":1214},"obj":"Species"},{"id":"393","span":{"begin":27,"end":36},"obj":"Species"},{"id":"394","span":{"begin":149,"end":158},"obj":"Disease"},{"id":"395","span":{"begin":214,"end":230},"obj":"Disease"},{"id":"396","span":{"begin":268,"end":283},"obj":"Disease"},{"id":"397","span":{"begin":313,"end":322},"obj":"Disease"},{"id":"398","span":{"begin":422,"end":430},"obj":"Disease"},{"id":"399","span":{"begin":461,"end":470},"obj":"Disease"},{"id":"400","span":{"begin":521,"end":531},"obj":"Disease"},{"id":"401","span":{"begin":612,"end":630},"obj":"Disease"},{"id":"402","span":{"begin":711,"end":719},"obj":"Disease"},{"id":"403","span":{"begin":731,"end":746},"obj":"Disease"}],"attributes":[{"id":"A388","pred":"tao:has_database_id","subj":"388","obj":"Tax:11309"},{"id":"A389","pred":"tao:has_database_id","subj":"389","obj":"Tax:2697049"},{"id":"A390","pred":"tao:has_database_id","subj":"390","obj":"Tax:11118"},{"id":"A391","pred":"tao:has_database_id","subj":"391","obj":"Tax:9606"},{"id":"A392","pred":"tao:has_database_id","subj":"392","obj":"Tax:9606"},{"id":"A393","pred":"tao:has_database_id","subj":"393","obj":"Tax:11309"},{"id":"A394","pred":"tao:has_database_id","subj":"394","obj":"MESH:D011014"},{"id":"A395","pred":"tao:has_database_id","subj":"395","obj":"MESH:D010996"},{"id":"A396","pred":"tao:has_database_id","subj":"396","obj":"MESH:D008206"},{"id":"A397","pred":"tao:has_database_id","subj":"397","obj":"MESH:D011014"},{"id":"A398","pred":"tao:has_database_id","subj":"398","obj":"MESH:C000657245"},{"id":"A399","pred":"tao:has_database_id","subj":"399","obj":"MESH:D011014"},{"id":"A400","pred":"tao:has_database_id","subj":"400","obj":"MESH:D007239"},{"id":"A401","pred":"tao:has_database_id","subj":"401","obj":"MESH:C000657245"},{"id":"A402","pred":"tao:has_database_id","subj":"402","obj":"MESH:C000657245"},{"subj":"388","pred":"source","obj":"LitCovid-PubTator"},{"subj":"389","pred":"source","obj":"LitCovid-PubTator"},{"subj":"390","pred":"source","obj":"LitCovid-PubTator"},{"subj":"391","pred":"source","obj":"LitCovid-PubTator"},{"subj":"392","pred":"source","obj":"LitCovid-PubTator"},{"subj":"393","pred":"source","obj":"LitCovid-PubTator"},{"subj":"394","pred":"source","obj":"LitCovid-PubTator"},{"subj":"395","pred":"source","obj":"LitCovid-PubTator"},{"subj":"396","pred":"source","obj":"LitCovid-PubTator"},{"subj":"397","pred":"source","obj":"LitCovid-PubTator"},{"subj":"398","pred":"source","obj":"LitCovid-PubTator"},{"subj":"399","pred":"source","obj":"LitCovid-PubTator"},{"subj":"400","pred":"source","obj":"LitCovid-PubTator"},{"subj":"401","pred":"source","obj":"LitCovid-PubTator"},{"subj":"402","pred":"source","obj":"LitCovid-PubTator"},{"subj":"403","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-PD-UBERON","denotations":[{"id":"T38","span":{"begin":214,"end":230},"obj":"Body_part"}],"attributes":[{"id":"A38","pred":"uberon_id","subj":"T38","obj":"http://purl.obolibrary.org/obo/UBERON_0000175"},{"subj":"T38","pred":"source","obj":"LitCovid-PD-UBERON"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T51","span":{"begin":27,"end":36},"obj":"Disease"},{"id":"T52","span":{"begin":122,"end":131},"obj":"Disease"},{"id":"T53","span":{"begin":149,"end":158},"obj":"Disease"},{"id":"T54","span":{"begin":268,"end":283},"obj":"Disease"},{"id":"T55","span":{"begin":302,"end":322},"obj":"Disease"},{"id":"T57","span":{"begin":313,"end":322},"obj":"Disease"},{"id":"T58","span":{"begin":422,"end":430},"obj":"Disease"},{"id":"T59","span":{"begin":450,"end":470},"obj":"Disease"},{"id":"T61","span":{"begin":461,"end":470},"obj":"Disease"},{"id":"T62","span":{"begin":472,"end":474},"obj":"Disease"},{"id":"T63","span":{"begin":521,"end":531},"obj":"Disease"},{"id":"T64","span":{"begin":612,"end":620},"obj":"Disease"},{"id":"T65","span":{"begin":621,"end":630},"obj":"Disease"},{"id":"T66","span":{"begin":711,"end":719},"obj":"Disease"},{"id":"T67","span":{"begin":731,"end":746},"obj":"Disease"},{"id":"T68","span":{"begin":737,"end":746},"obj":"Disease"}],"attributes":[{"id":"A51","pred":"mondo_id","subj":"T51","obj":"http://purl.obolibrary.org/obo/MONDO_0005812"},{"id":"A52","pred":"mondo_id","subj":"T52","obj":"http://purl.obolibrary.org/obo/MONDO_0005812"},{"id":"A53","pred":"mondo_id","subj":"T53","obj":"http://purl.obolibrary.org/obo/MONDO_0005249"},{"id":"A54","pred":"mondo_id","subj":"T54"
