Estimates of the rate of infection and asymptomatic COVID-19 disease in a population sample from SE England	2020-10-15		.txt	text/plain	3730	197	51	METHODS: We undertook enzyme linked immunosorbent assay characterisation of IgM and IgG responses against SARS-CoV-2 spike glycoprotein and nucleocapsid protein of 431 unselected general-population participants of the TwinsUK cohort from South-East England, aged 19-86 (median age 48; 85% female). 382 participants completed prospective logging of 14 COVID-19 related symptoms via the COVID Symptom Study App, allowing consideration of serology alongside individual symptoms, and a predictive algorithm for estimated COVID-19 previously modelled on PCR positive individuals from a dataset of over 2 million. We undertook a population-based study of the humoral immune response to SARS-CoV-2, with regards to longitudinal clinical symptoms collected through a mobile phone app in a population-based sample of 431 TwinsUK volunteers. For three months prior to the visit, the majority of participants had completed regular logging of symptoms, via the C-19 Covid Symptom Study app 5 , enabling measurement of antibody response to COVID-19 with regards to clinical symptoms.	./cache/cord-322812-9u3ptqjs.txt	./txt/cord-322812-9u3ptqjs.txt
