Information on lung infection

Lung infection encompasses several symptoms, such as cough, inflammation of the lungs, pneumonia, pulmonary congestion, bronchitis, pulmonary embolism and so on. One of the most common lung infections is pneumonia. Inflammation of the lungs, due to pus and infection, results in decrease in the oxygen uptake. Fatigue, sharp chest pain, rapid breathing, fever, cold, chills, abdominal pain and cough are the common symptoms. Tuberculosis is yet another commonly seen lung infection. Caused by Mycobacterium tuberculosis, it is transmitted through air. Tuberculosis is characteristic of repeated and severe coughing, fatigue, loss of weight, chills, night sweats and coughing up blood. Inflammation of the respiratory passages is referred to as bronchitis. Irritation of the mucosal lining is seen. Inhalation of fumes, smoke and chemical solvents are associated with bronchitis. Individuals with a weak immunity are more vulnerable. Asthma or wheezing is inflammation of the airway passage with increased sensitivity to certain triggers, like pollen, dust and dander. Symptoms of asthma include cough, speaking and breathing difficulty, wheezing and tightness of the chest. An asthmatic attack begins slowly and stays for a few hours to few days.
