What are the nose and throat infections?

An example of a nose infection is a sinus infection.

Yes, but the chance is not big.

It is actually the throat, but your tonsils get inflammed so nothing else can effect your throat.

Most throat infections are relatively benign, but some (strep throat is an example) can lead to other problems that could be life-threatening. If you have a high fever, or if your throat is too sore...

you probably just have a cold. if your super worried go see a doctor.
