Possible SARS Coronavirus Transmission during Cardiopulmonary Resuscitation
Infection of healthcare workers with the severe acute respiratory syndrome-associated coronavirus (SARS-CoV) is thought to occur primarily by either contact or large respiratory droplet transmission. However, infrequent healthcare worker infections occurred despite the use of contact and droplet precautions, particularly during certain aerosol-generating medical procedures. We investigated a po...
متن کاملExposure to influenza virus aerosols during routine patient care.
BACKGROUND Defining dispersal of influenza virus via aerosol is essential for the development of prevention measures. METHODS During the 2010-2011 influenza season, subjects with influenza-like illness were enrolled in an emergency department and throughout a tertiary care hospital, nasopharyngeal swab specimens were obtained, and symptom severity, treatment, and medical history were recorded...
متن کاملNoninvasive ventilation and the potential risk of transmission of infection.
Noninvasive positive-pressure ventilation (NPPV) is becoming increasingly used in patients with acute respiratory failure caused by a wide range of infectious aetiologies such as human-adapted avian influenza, aspergillosis and varicella [2–4], in order to avoid intubation or as a bridge to invasive mechanical ventilation. Substantial exposure to exhaled air occurs within a 0.5-m radius of pati...
متن کاملInfection prevention and control measures for acute respiratory infections in healthcare settings: an update.
Viruses account for the majority of the acute respiratory tract infections (ARIs) globally with a mortality exceeding 4 million deaths per year. The most commonly encountered viruses, in order of frequency, include influenza, respiratory syncytial virus, parainfluenza and adenovirus. Current evidence suggests that the major mode of transmission of ARls is through large droplets, but transmissio...
متن کاملAerosol Generating Procedures and Risk of Transmission of Acute Respiratory Infections to Healthcare Workers: A Systematic Review
Aerosol generating procedures (AGPs) may expose health care workers (HCWs) to pathogens causing acute respiratory infections (ARIs), but the risk of transmission of ARIs from AGPs is not fully known. We sought to determine the clinical evidence for the risk of transmission of ARIs to HCWs caring for patients undergoing AGPs compared with the risk of transmission to HCWs caring for patients not ...
