To date, these models have only considered the culmination or peak of\r\nsymptoms, which is not suitable for the early detection of infection. We aimed to estimate the probability of an\r\nindividual being infected with SARS-CoV-2 on the basis of early self-reported symptoms to enable timely self-isolation\r\nand urgent testing.\r\nMethods In this large-scale, prospective, epidemiological surveillance study, we used prospective, observational,\r\nlongitudinal, self-reported data from participants in the UK on 19 symptoms over 3 days after symptoms onset and\r\nCOVID-19 PCR test results extracted from the COVID-19 Symptom Study mobile phone app. We divided the study\r\npopulation into a training set (those who reported symptoms between April 29, 2020, and Oct 15, 2020) and a test set\r\n(those who reported symptoms between Oct 16, 2020, and Nov 30, 2020), and used three models to analyse the selfreported\r\nsymptoms: the UK’s National Health Service (NHS) algorithm, logistic regression, and the hierarchical\r\nGaussian process model we designed to account for several important variables (eg, specific COVID-19 symptoms,\r\ncomorbidities, and clinical information). Model performance to predict COVID-19 positivity was compared in terms\r\nof sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) in the test set. For the\r\nhierarchical Gaussian process model, we also evaluated the relevance of symptoms in the early detection of COVID-19\r\nin population subgroups stratified according to occupation, sex, age, and body-mass index.\r\nFindings The training set comprised 182 991 participants and the test set comprised 15 049 participants. When trained\r\non 3 days of self-reported symptoms, the hierarchical Gaussian process model had a higher prediction AUC (0·80\r\n[95% CI 0·80–0·81]) than did the logistic regression model (0·74 [0·74–0·75]) and the NHS algorithm (0·67\r\n[0·67–0·67]). AUCs for all models increased with the number of days of self-reported symptoms, but were still high\r\nfor the hierarchical Gaussian process model at day 1 (0·73 [95% CI 0·73–0·74]) and day 2 (0·79 [0·78–0·79]). At\r\nday 3, the hierarchical Gaussian process model also had a significantly higher sensitivity, but a non-statistically lower\r\nspecificity, than did the two other models. The hierarchical Gaussian process model also identified different sets of\r\nrelevant features to detect COVID-19 between younger and older subgroups, and between health-care workers and\r\nnon-health-care workers. When used during different pandemic periods, the model was robust to changes in\r\npopulations.\r\nInterpretation Early detection of SARS-CoV-2 infection is feasible with our model. Such early detection is crucial to\r\ncontain the spread of COVID-19 and efficiently allocate medical resources.\r\nFunding ZOE, the UK Government Department of Health and Social Care, the Wellcome
