If inflammation affects both lungs, the infection is termed double pneumonia. If it affects one lung, it is termed single pneumonia. If it affects only a certain lobe of a lung it's termed lobar pneumonia. Most pneumonias are caused by bacteria and viruses, but some pneumonias are caused by inhaling toxic chemicals that damage lung tissue.
Laryngitis is an inflammation of the voice box (vocal cords). The most common cause of acute laryngitis is infection, which inflames the vocal cords. Symptoms may vary from degree of laryngitis and age of the person (laryngitis in infants and children is more commonly caused by croup). Common symptoms include
- a "barky" cough,
- a hoarse cough,
- runny nose,
- dry cough, and
- loss of voice.
Chronic laryngitis generally lasts more than three weeks. Causes other than infection include smoking, excess coughing, GERD, and more. Treatment depends on the cause of laryngitis.
