Underdetection of COVID-19 cases in France in the exit phase following lockdown	2020-08-12		.txt	text/plain	5252	319	48	Using age-stratified transmission models parameterized to behavioral data and calibrated to regional hospital admissions, we estimated that 69,115 [58,072-77,449] COVID-19 symptomatic cases occurred, suggesting that 9 out of 10 cases with symptoms were not ascertained. In France, the surveillance strategy implemented by authorities to exit lockdown on May 11, 2020 was multifold 2,3 and based on an expanded case definition for COVID-19 suspect cases to guide clinical diagnosis 4 ; recommendations to the general population to seek healthcare even in presence of mild symptoms; prescription of diagnostic tests to suspect cases by general practitioners for systematic and comprehensive testing; isolation of confirmed cases and tracing of their contacts. Here we estimated the rate of detection of COVID-19 symptomatic cases in France in May-June 2020 after lockdown, through the use of virological and participatory syndromic surveillance data coupled with mathematical transmission models calibrated to regional hospitalizations.	./cache/cord-320636-mvtux07x.txt	./txt/cord-320636-mvtux07x.txt
