Risk Factors of Pneumonia

Pneumonia is inflammation and infection of the lungs, causing difficulty breathing, cough and chest pain. Pneumonia can either affect one or both lungs and there are various forms of the disease. The most common causes of pneumonia are: pulmonary infection with viruses (influenza, herpes simplex virus, varicella-zoster, adenovirus, respiratory syncytial virus), gram positive bacteria (Streptococcus pneumoniae, Staphylococcus aureus, Streptococcus pyogenes) and gram negative bacteria (Haemophilus influenzae, Klebsiella pneumoniae, Neisseria meningitides, Pseudomonas aeruginosa). Pneumonia can also be caused by infection with mycoplasmas (Mycoplasma pneumoniae), small infectious agents that share the characteristics of both viruses and bacteria.
