Diagnosis is often based on symptoms and physical examination.[8] Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis.[8] The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia.[17] Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, a poor ability to cough (such as following a stroke), and a weak immune system.[5][7] Vaccines to prevent certain types of pneumonia (such as those caused by Streptococcus pneumoniae bacteria or that linked to influenza) are available.[10] Other methods of prevention include hand washing to prevent infection, and not smoking.[10] Treatment depends on the underlying cause.[18] Pneumonia believed to be due to bacteria is treated with antibiotics.[11] If the pneumonia is severe, the affected person is generally hospitalized.[18] Oxygen therapy may be used if oxygen levels are low.[11]
