Coronavirus lingers in air longer than previously thought, Finland scientists claim

1. Researchers modelled the airborne movement of aerosol particles smaller than 20 micrometres.

2. For a dry cough, which is a typical symptom of COVID-19, the particle size is typically less than 15 micrometres.

3. Extremely small particles of this size do not sink on the floor, but instead, move along in the air currents or remain floating in the same place.
