Pneumonia is the infection of the lungs leading to the inflammation of the lungs. Pneumonia can occur in one or both of the lungs. Pneumonia is caused by certain bacteria, viruses, and fungi.
Pneumonia usually spreads through air (airborne disease) contaminated with Pneumonia-causing pathogens. Inhaling a foreign material (here, a material foreign or unusual to the lungs) such as food, liquid or drink, vomit, or saliva into the lungs can also cause Pneumonia, which is termed as Aspiration Pneumonia.
Common symptoms of Pneumonia include dry cough or cough with mucus / phlegm (productive cough or wet cough), fever, chills, and difficulty in breathing. Pneumonia caused by bacteria (Bacterial pneumonia) is treated with antibiotics. To treat Pneumonia caused by viruses (Viral Pneumonia), antiviral medicines may be prescribed by a physician. Antipyretics (medicines that reduce fever) are prescribed to reduce body temperature to normal. In severe cases, hospitalization is necessary.
