Also, children do not wash their hands as frequently as adults. They also put their fingers in their mouth, nose, and eyes too often, helping germs to spread quickly.

In case you suffer from problems with the heart or lungs, you are at more risk of experiencing an upper respiratory infection. People with weak immune systems might have severe infections. Most of the time, Antibiotic medicines are beneficial in treating respiratory Infections.
