What are the Major Causes of Lower Respiratory Infections?

Lower respiratory infections are a group of infectious diseases that affect the lungs and breathing passages. The major causes of lower respiratory infections are viruses, bacteria, fungi and parasites.

A virus is a microscopic infectious agent which can only replicate inside the living cells of an organism. Bacteria are a type of microorganism that can cause disease by colonizing tissues in the body, releasing toxins or invading body organs.
