Traces of the SARS-CoV-2 coronavirus that causes COVID-19 can be detected in microscopically small fluid droplets exhaled during a very short time span. This is the finding of a new study from the University of Gothenburg. The measurement was carried out primarily with an advanced research instrument developed by the publishing research team.
Infection spread with exhaled air is well known, but now the researchers show that a few breaths are sufficient for detecting traces of viruses in microscopically small fluid droplets (i.e. particles) exhaled from small airways, at least early in the course of COVID-19.
