Can bacteria spread through phlegm?

If you spit out some phlegm, does the bacteria in it float in the air? Or does the bacteria only spread from the particles coughed out.

Can bacteria spread through phlegm?
Bacteria can be spread through air droplets, such as in tuberculosis. This happens with any exhalation such as coughing, talking, sneezing, that causes particles larger than 5 micrograms. The particles usually travel up to 3 feet away; but anyone entering the room should wear a mask.


Same goes for viruses, including chicken pox, flu, viral pneumonia, measles, etc.
Reply:both in the air and the phlegm
