Health Care Workers and Patients as Trojan Horses: a COVID19 ward outbreak	2020-07-04		.txt	text/plain	3432	180	58	Subsequent investigation over a 14 day period revealed symptoms in 23 staff members and five linked cases in patients on the same ward. Staff members and patients can act as Trojan horses carrying infection into and around the hospital, setting up unexpected transmission events. An in house real time PCR assay for COVID-19 was carried out on dry throat swabs taken from symptomatic patients and staff members working on the ward. HCW cases were defined as (A) a member of staff from the affected ward and (B) compatible symptoms for COVID-19 (C) onset of infection during the outbreak period. Four of the five staff members with very early onset of infection were working with the index case during the likely infectious period ( Figure 3 ). In this case infection was most likely introduced by an asymptomatic or minimally symptomatic HCW and then transferred via a longstanding patient from ITU to a previously negative medical ward.	./cache/cord-262653-v1to1mrp.txt	./txt/cord-262653-v1to1mrp.txt
