Health care workers in Western countries do not regularly use any face masks, except when in theatre. <\/p>\n The study was conducted in China where face masks are commonplace in all health settings. Close to 1700 doctors and nurses in 19 Beijing hospitals were recruited for the study. Staff in respiratory and emergency departments, who are more likely to come across these sorts of infections, took part. <\/p>\n In a surprise finding, those who continuously used the N95 face masks had a protective effect not only against clinical respiratory infections, but bacterial ones too. <\/p>\n \"Outbreaks in hospitals tend to be viral. No-one has thought of bacterial diseases as being responsible for outbreaks,\" Professor MacIntyre says. \"In addition, bacterial co-infections commonly occur during influenza outbreaks. We suspect that if you have one infection it predisposes you to the other. There is a complex synergy between bacteria and viruses in the respiratory tract.\" <\/p>\n <\/p>\n Go here to see the original:<\/p>\n Protecting health care workers<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Public release date: 25-Feb-2013 [ | E-mail | Share ] Contact: Susi Hamilton susi.hamilton@unsw.edu.au<\/a> 61-422-934-024 University of New South Wales Health care workers who consistently wear special fitted face masks while on duty are much less likely to get clinical respiratory and bacterial infections, according to new research led by University of New South Wales (UNSW) academics.
