User: Pneumonia is caused by _____.

Weegy: Bacteria and viruses are the primary causes of pneumonia. [ When a person breathes pneumonia-causing germs into his lungs and his body's immune system cannot otherwise prevent entry, the organisms settle in small air sacs called alveoli and continue multiplying. As the body sends white blood cells to attack the infection, the sacs become filed with fluid and pus - causing pneumonia. ]
