cord-319504-jb455t9p	Suess, Thorsten	The role of facemasks and hand hygiene in the prevention of influenza transmission in households: results from a cluster randomised trial; Berlin, Germany, 2009-2011	2012-01-26		.txt	text/plain	6952	344	50	BACKGROUND: Previous controlled studies on the effect of non-pharmaceutical interventions (NPI) namely the use of facemasks and intensified hand hygiene in preventing household transmission of influenza have not produced definitive results. When analysing only households where intervention was implemented within 36 h after symptom onset of the index case, secondary infection in the pooled M and MH groups was significantly lower compared to the control group (adjusted odds ratio 0.16, 95% CI, 0.03-0.92). Since 2006, the World Health Organisation (WHO) and other organisations have highlighted the need for controlled trials to assist in formulating recommendations on the use of non-pharmaceutical interventions (NPI)such as facemasks or hand hygiene measures -as options to prevent influenza transmission, particularly in households [1, 2] . In intention-to-treat analysis, none of the four household based trials was able to show significant reductions in secondary attack rates (SAR) when comparing intervention to control groups.	./cache/cord-319504-jb455t9p.txt	./txt/cord-319504-jb455t9p.txt
