Quote:

"Keep out of 'spray range,'" is the warning given to residents of Boston by Health Commissioner Woodward [...]

In explaining his meaning of the phrase "spray range," the commissioner said that by the operation of coughing and sneezing a person suffering from the epidemic can send germs into the air for a distance of from eight to 15 feet. A well person standing within this rage can be readily infected by breathing in these germs. For this reason he urges the public to be on guard against getting into crowds or even conversing in the open air with persons who may be infected.

It isn't even necessary for the infected person to cough or sneeze, according to the commissioner, in order to infect well persons within "spray range." The mere pronunciation of such letters as t, d, p and many others will send germs into the air for a considerable distance."
