A systematic review	2020-06-24		.txt	text/plain	2235	153	57	CONCLUSIONS: Although limited, current evidence suggests that viral carriage on the outer surface of surgical masks worn by HCW treating patients with clinical respiratory illness is low and there was not strong evidence to support the assumption that mask use may increase the risk of viral transmission. During the current novel coronavirus disease 2019 (SARS-CoV-2, COVID-19) pandemic, the Ministry of Health (MOH) and District Health Boards (DHB) have not recommended routine use of surgical masks for healthcare workers (HCW) in emergency departments (ED) in New Zealand (NZ). Articles were included if they were clinical studies that reported virus detection on masks worn by HCW. Systematic review evidence from a previous coronavirus pandemic suggests that general use of masks may be protective for HCW in this setting, 20 21 with a Number Needed to Treat (NNT) of six to prevent one HCW infection (meta-analysis of case control studies).	./cache/cord-316266-6m9g3bdr.txt	./txt/cord-316266-6m9g3bdr.txt
