Characteristics of COVID-19 in Homeless Shelters: A Community-Based Surveillance Study	2020-09-15		.txt	text/plain	4018	241	53	MEASUREMENTS: The primary outcome measure was test positivity rate of SARS-CoV-2 infection at shelters, determined by dividing the number of positive cases by the total number of participant encounters, regardless of symptoms. CONCLUSION: Active surveillance and surge testing were used to detect multiple cases of asymptomatic and symptomatic SARS-CoV-2 infection in homeless shelters. Surge testing was initiated on 30 March 2020 (and continued through 24 April) in collaboration with Public Health-Seattle & King County's Communicable Disease Epidemiology Team to conduct contact tracing at 6 shelters where cases of SARS-CoV-2 were previously detected ( Figure 2 ). We calculated the test positivity rate of SARS-CoV-2 infection at shelters by dividing the number of positive cases by the total number of participant encounters in the study period. Overall, 2% of participant encounters involved positive SARS-CoV-2 results, with most cases detected through surge testing events.	./cache/cord-309633-1cd74xdl.txt	./txt/cord-309633-1cd74xdl.txt
