Routine infection-control recommendations to decrease the risk for transmission of seasonal influenza to HCP include vaccination, isolation of infected patients in single rooms, and use of standard precautions and droplet precautions. For infections with the novel influenza A (H1N1) virus, because of the lack of a vaccine and little initial information regarding the severity and transmissibility of the virus, CDC’s interim infection-control recommendations for the care of patients with such infections have included the use of fit-tested N95 respirators, eye protection, and contact precautions in addition to routine infection-control practices applied to seasonal influenza. In addition, CDC has recommended that aerosol-generating procedures (e.g., bronchoscopy) should be performed in an airborne infection–isolation room with negative pressure air handling. In this analysis, among the 11 HCP infected because of probable or possible patient to HCP transmission for whom information was available, none adhered to these recommended practices completely.
