Nonpharmaceutical Measures for Pandemic Influenza in Nonhealthcare Settings—Personal Protective and Environmental Measures
|Types of interventions||No. studies identified||Study designs included†||Main findings|
||The evidence from RCTs suggested that hand hygiene interventions do not have a substantial effect on influenza transmission.
||We did not identify research evaluating the effectiveness of respiratory etiquette on influenza transmission.
||The evidence from RCTs suggested that the use of face masks either by infected persons or by uninfected persons does not have a substantial effect on influenza transmission.
|Surface and object cleaning||3||RCT, observational studies||There was a limited amount of evidence suggesting that surface and object cleaning does not have a substantial effect on influenza transmission.|
*NA, not available; RCT randomized controlled trial.
†In these systematic reviews, we prioritized RCTs, and only considered observational studies if there were a small number of RCTs. Our rationale was that with evidence from a larger number of RCTs, additional evidence from observational studies would be unlikely to change overall conclusions.
