What are infectious lung diseases?

The term lung disease refers to many disorders affecting the lungs, such as asthma, COPD, infections like influenza, pneumonia and tuberculosis, lung cancer, and many other breathing problems.

What causes bacterial lung infections?

The most common causes of bacterial lung infections in normal hosts include Streptococcus pneumoniae, Haemophilus species, Staphylococcus aureus and Mycobacterium tuberculosis. In compromised hosts, the bacterial causes of pneumonia are much broader, including species not usually considered of high virulence in humans.

Are lung infections infectious?

What are the top 5 lung diseases?

The most common lung diseases include:

  • Asthma.
  • Collapse of part or all of the lung (pneumothorax or atelectasis)
  • Swelling and inflammation in the main passages (bronchial tubes) that carry air to the lungs (bronchitis)
  • COPD.
  • Lung cancer.
  • Lung infection (pneumonia)
  • Abnormal buildup of fluid in the lungs (pulmonary edema)

How do I get rid of a bacterial infection in my lungs?


  1. Get lots of rest.
  2. Drink plenty of fluids (they’ll loosen up the gunk in your lungs so you can cough it out).

    Tuberculosis. A sufferer of TB looks sick with muscle wasting,weight loss,poor muscle tone and dry flaky skin.

  • SARS. The SARS virus spreads from person to person through droplet transmission from the infected person to the mucus membranes of another person.
  • Bronchitis.
  • Pneumonia.
  • What is contagious disease affecting the lungs?
