The dispersion of airborne viruses can play an important role in the spread of a disease. Especially for short or moderate emission periods - such as emissions from farms or accidental releases from laboratories or industrial plants - indoor concentrations can be significantly lower than outdoor concentrations. The relationships between these two concentrations are analysed for continuous, temporary and instantaneous releases. The efficiency of sheltering as a protective measure for persons or animals is discussed.
