The signs and symptoms of pneumonia vary from mild to severe. Many factors affect how serious pneumonia is, including the type of germ causing the infection and your age and overall health.

Pneumonia Symptoms in Elderly Individuals. For most adults, infectious pneumonia first presents symptoms similar to those of the common cold: sneezing, coughing, and a sore throat. These relatively benign symptoms are soon followed by a high fever, chills, green or yellow sputum, and shortness of breath.Pain on inhalation is sometimes present. Pneumonia is common in patients who have difficulty swallowing. 2  Saliva and oral bacteria may be inhaled into the lungs, causing aspiration pneumonia or bacterial pneumonia. 3  In these patients, physical and feeding therapy, oral care, and maintaining an upright posture are all shown to decrease the incidence of pneumonia.
