In this review authors searched for randomized trials comparing N95 respirators and surgical masks for preventing epidemic influenza in healthcare settings.Medical masks and N95 respirators reduce the risk of respiratory infection when worn by healthcare workers, but universal use of N95 respirators throughout a work shift is likely to be less acceptable because of greater discomfort Disposable, cotton or paper masks are not recommended for protecting healthcare workers from respiratory ...

The Corley systematic review found insufficient evidence to determine the effects of high-flow nasal cannula compared with other forms of respiratory support for adult patients in intensive care units. Agarwal et al. reported that high-flow nasal cannula may reduce the need for invasive ventilation and escalation of therapy when compared with conventional oxygen therapy in patients with acute hypoxemic respiratory failure. However, the relevance of the findings to COVID-19 patients is uncertain ...

Most systematic reviews showed that early identification and isolation of patients in hospital wards or at home can be effective in reducing the spread of respiratory viruses and may prevent transmssion in healthcare facilities and in the community. Isolating exposed individuals in addition of ill ones is also an effective intervention. However people were ambivalent about adopting isolation in some contexts. A rapid review showed that the main influencers of adherence to quarantine were a ...

Most reviews concluded that ward closures, border controls, and screening at ports of entry are effective at controlling outbreaks of infectious disease, yet it is uncertain due to the lack of controlled studies. On the other hand, no evidence has been found of a major effect of surface or object cleaning in the transmission of influenza.
