Lung Infections

A chest infection affects your lungs, either in the larger airways (bronchitis) or in the smaller air sacs (pneumonia). It is likely that your own immune system will deal with the infection, as most chest infections are caused by a virus. Lower respiratory infection can be caused by bronchitis, pneumonia, respiratory syncytial virus (RSV), severe flu, or tuberculosis.

Lower Respiratory Infection Symptoms

  • Severe cough that may produce mucus (phlegm)
  • Shortness of breath
  • Chest tightness
  • Wheezing when exhaling

These infections usually require medical treatment to overcome.
