How do you get a bacterial infection in your lungs?

Both viral and bacterial respiratory tract infections are contagious and spread from person to person through respiratory droplets emitted by coughing or sneezing. Transmission of these infections can also occur by touching the mouth or nose by hand, or by touching another object exposed to the virus or bacteria.
