DefinitionEdit

Pneumonia, is an inflammatory condition of the lung. It is most often caused, by an infection from bacteria.[1][2]


Onset of illnessEdit

Symptoms for pneumonia, typically include, cough, fatigue, chills, and shortness of breath. Each of the symptoms, occurs with different frequencies.[3]


ElderlyEdit

In the elderly, confusion, may be the most prominent sign,[3] and fever, is less likely to be present.


Children Early SymptomsEdit

In children, under the age of five, fever, cough, and fast or difficult breathing, are the most common symptoms.[4]


Children Severe PneumoniaEdit

More severe signs, and symptoms, in children may include, blue-tinged skin, unwillingness to drink, convulsions, ongoing vomiting, extremes of temperature, or a decreased level of consciousness.[4][5]


CausesEdit

Pneumonia, fills the lung's alveoli with fluid, limiting how much oxygen, can be absorbed. The alveolus, on the left, is normal, whereas, the one on the right, is full of fluid from pneumonia.


Bacterial PneumoniaEdit

Pneumonia, is usually caused by infection from bacteria, or viruses. It is less commonly caused by other microorganisms, certain medications, and conditions, such as autoimmune diseases.[1][6]


Risk factorsEdit

Risk factors for pneumonia, include smoking, a poor ability to cough, (such as after a stroke or surgery), and other lung diseases, such as cystic fibrosis,, COPD,, and asthma.[7]


DiagnosisEdit

Diagnosis, is often based on symptoms, and physical examination alone.[8]


Diagnosis - Other MethodsEdit

Chest X-ray, blood tests, and culture of the sputum, may help confirm the diagnosis.[8]


ClassificationEdit

Where, and how a pneumonia was acquired, can have a profound impact on survival. Examples are, community-acquired, or hospital-acquired pneumonia. [9]


PreventionEdit

Because, most pneumonias, are acquired from someone else that is infected, handwashing, and wearing surgical masks around the sick, are the most important preventative steps[10].


VaccineEdit

Vaccines, to prevent certain types of pneumonia, are available.[11]


Other MethodsEdit

Other methods of prevention, include smoking cessation, and treating underlying illnesses, (such as diabetes and HIV), properly.[11]


TreatmentEdit

Antibiotics by mouth, rest, and simple analgesics and fluids, are usually enough, to treat uncomplicated pneumonia.[12]


ChildrenEdit

In children, those with respiratory distress, should be hospitalized.[13]


PrognosisEdit

With treatment, most types of bacterial pneumonia, will stabilize in 3–6 days.[14] It often takes a few weeks before most symptoms resolve.[14].


Severe pneumoniaEdit

If the pneumonia is severe, the affected person is generally hospitalized, [15] and oxygen therapy may be necessary.[16]
