Causes
A sore throat can be caused by many factors. It is estimated that up to 90 percent of reported cases are associated with viral infections, such as the common cold, mononucleosis, mumps, chickenpox, measles, and influenza. Some other common triggers include air pollution, dry air, allergies, and smoke from tobacco products.
On the other hand, most cases of strep throats are caused by bacteria known as group A Streptococcus or Streptococcus pyogenes. You would be infected when touching the mouth, nose, or eyes after being exposed to the microorganisms, which can be found in different areas in your house or office. [4.2] [4.3]
