A 3D model is helping to illustrate how COVID-19 can spread indoors.

The model was created by researchers in Finland, and was designed to represent a grocery store with shelving and ventilation.

Researchers say the model shows that when someone coughs, their particles can spread outside of the immediate area and can take several minutes to dilute.
