Detailed Answer:
Hello,
Thanks for posting your query in HealthcareMagic,

I have read through your query and will try to explain you in the best way possible,

Throat is an open airway, which allows the passage of inhaled air to the lungs, and also the food particles to the esophagus. When any foreign materials travel along the throat, it may get lodged in and cause an infection.
Causative organisms can be bacterial, viral, environmental.
The modes of treatment varies according to the causative organisms.

If you get repetitive attacks of throat infection, it is worthwhile to get checked for allergic testing, presence of adenoids, hypersensitive airways, sinusitis etc. You may consider consulting with an ENT physician for further management.

Kindly update if you have any further symptoms,

Regards
