New study shows how long coronavirus can stay airborne

The University Of Wuhan’s study took samples of 30 sites across Wuhan where the virus first broke out.

It found levels of airborne virus particles in the majority of public areas was too low to be detectable.

The main exception was in two areas prone to crowding – including the entrance of a department store.

In open, public areas outside the hospitals such as residential buildings and supermarkets, the study said the concentrations of COVID-19 “aerosols” were generally low.

Meanwhile, in the hospitals, the number of virus particles detected in isolation wards and ventilated patient rooms were very low, but elevated in the patients’ toilet areas, which were not ventilated.
