    Understanding the temporal dynamics of COVID-19 patient phenotypes is necessary to derive fine-grained resolution of pathophysiology. Here we use state-of-the-art deep neural networks over an institution-wide machine intelligence platform for the augmented curation of 15.8 million clinical notes from 30,494 patients subjected to COVID-19 PCR diagnostic testing. By contrasting the Electronic Health Record (EHR)-derived clinical phenotypes of COVID-19-positive (COVIDpos, n=635) versus COVID-19-negative (COVIDneg, n=29,859) patients over each day of the week preceding the PCR testing date, we identify anosmia HP anosmia MESHD/dysgeusia (37.4-fold), myalgia HP myalgia MESHD/ arthralgia HP arthralgia MESHD (2.6-fold), diarrhea HP diarrhea MESHD (2.2-fold), fever HP fever MESHD/ chills HP (2.1-fold), respiratory difficulty (1.9-fold), and cough HP (1.8-fold) as significantly amplified in COVIDpos over COVIDneg patients. The specific combination of cough HP cough MESHD and diarrhea HP diarrhea MESHD has a 3.2-fold amplification in COVIDpos patients during the week prior to PCR testing, and along with anosmia HP anosmia MESHD/dysgeusia, constitutes the earliest EHR-derived signature of COVID-19 (4-7 days prior to typical PCR testing date). This study introduces an Augmented Intelligence platform for the real-time synthesis of institutional knowledge captured in EHRs. The platform holds tremendous potential for scaling up curation throughput, with minimal need for retraining underlying neural networks, thus promising EHR-powered early diagnosis for a broad spectrum of diseases.
