Not only does mucus production increase during a lung infection, but the mucus itself undergoes changes, states About.com. It often changes color or becomes sticky and thick. Because of the mucus, a person also experiences a productive cough, or a cough that hacks up mucus. If the lung infection is bronchitis, the mucus might appear to be bloody, notes WebMD. Mucus as a result of pneumonia can appear reddish-brown or green.

Other bronchitis and pneumonia symptoms include a fever, chills and fatigue, according to WebMD. An individual with bronchitis has trouble breathing, suffering from chest tightness and wheezing. Someone with pneumonia experiences shallow breathing, shortness of breath and a rapid heartbeat. Some severe cases of pneumonia and bronchitis require medication and antibiotics.

If the infection is an acute respiratory infection, a virus infects not just the lungs, but the windpipe as well, states Healthline. This condition severely restricts breathing, limiting the flow of oxygen throughout the body and possibly causing death. Other than breathing problems, an individual also experiences a sore throat, congestion, a runny nose and body aches.
