CoVid can spread silently table to adjacent though distanced table within a poorly ventilated indoor restaurant.  Chinese engineers and epidemiologists now report their study of a Wuhan restaurant where one CoVid-infected person spread disease to 9 others at the same and 2 nearby tables.

 

Tracer gas and computational fluid dynamics defined spread of droplets and aerosols from the infected person to others 3 tables in one end of the dining hall without fresh outdoor air.  None of the other 68 diners at the other 15 tables nor the restaurant servers and staff became infected.

 

It is dangerous to spend time eating indoors without a mask in a space without fresh, outdoor air.
