The purpose of this study is to gain a better understanding of the production of infectious aerosols by patients with influenza, and to compare this to the levels of biomarkers in the blood of these patients. To do this, aerosols produced by volunteer subjects with influenza will be collected and tested for influenza virus, and the levels of influenza infection-associated microRNA molecules will be measured in blood samples from these subjects.
This is a reinstatement with change. Work under the previous approval showed that patients infected with influenza virus produce airborne particles containing viable airborne influenza virus during both breathing and coughing, but that breathing may generate more airborne infectious material than coughing over time. However, this work was hampered because the amounts of influenza virus in almost all of the aerosol samples were below the limit of quantification.
