Flu spreads easier than previously thought: no coughing or sneezing necessary

The common believe is that the flu spreads by droplets generated by coughing or sneezing, or by contact with contaminated surfaces. A new study suggests spreading the flu virus (influenza) is actually much easier: breathing is enough! Infected persons contaminate the air with influenza viral particles just by breathing, especially during the initial phase of the flu. The droplets stay in the air for a long time and they can easily be taken in by other people. This may pave the way for improving ventilation systems in public spaces in order to minimize the risk of transmission.
