Airborne Transmission

  • Researcher Turns Surgical Mask Into a Virus Killer
    A University of Alberta engineering researcher has developed a new way to treat common surgical masks so they are capable of trapping and killing airborne viruses. His research findings appear in the prestigious journal Scientific Reports, published by Nature Publishing ...More

  • Traces of Resistant Bacteria Found in Polluted Air
    Polluted city air has now been identified as a possible means of transmission for resistant bacteria. Researchers in Gothenburg have shown that air samples from Beijing contain DNA from genes that make bacteria resistant to the most powerful antibiotics we have. "This may ...More

  • Sneezing Produces Complex Fluid Cascade, Not a Simple Spray
    Here's some incentive to cover your mouth the next time you sneeze: New high-speed videos captured by MIT researchers show that as a person sneezes, they launch a sheet of fluid that balloons, then breaks apart in long filaments that destabilize, and finally disperses as a ...More

  • How Flu Viruses Gain the Ability to Spread
    Flu viruses come in many strains, and some are better equipped than others to spread from person to person. Scientists have now discovered that the soft palate -- the soft tissue at the back of the roof of the mouth -- plays a key role in viruses' ability to travel through ...More

  • Noroviruses Can Spread by Air
    Noroviruses, a group of viruses responsible for more than half of global gastroenteritis cases, can spread by air up to several meters from an infected person according to a new study by Université Laval researchers. The discovery, details of which are presented in ...More

  • Strength of Coughing May Forecast the Likelihood of Spread of Multidrug-Resistant Organisms
    Current recommendations indicate that patients who are coughing and have multidrug-resistant organisms (MDROs) in their sputum are considered to be shedders and should be cared for in single-room isolation at least until symptoms resolve. Airborne spread and subsequent ...More

  • Human Movement in an Airplane Cabin Can Affect Airborne Disease Transmission
    Airborne transmission of respiratory infectious disease in an indoor environment (such as an airplane cabin, conference room, hospital, isolated room and inpatient ward) may cause outbreaks of infectious diseases, which may lead to many infection cases and significantly ...More

  • Study Reports Germs Travel Farther Than Originally Thought
    Each sneeze or cough generates a cloud of invisible gas that propels droplets of infectious material farther than originally thought, and smaller droplets actually travel farther than larger ones. A new study from MIT researchers published in the Journal of Fluid Mechanics ...More

  • Study Examines the Way Droplets from Coughs and Sneezes Stay Airborne for Long Distances
    A novel study by MIT researchers shows that coughs and sneezes have associated gas clouds that keep their potentially infectious droplets aloft over much greater distances than previously realized. "When you cough or sneeze, you see the droplets, or feel them if someone ...More
