Runny nose, sneezing, sore throat and annoying cough, we all suffer at some time during a common cold. As children reach as many as eight or more colds per year, this contagious viral infection that affects the upper respiratory tract is the most common infectious disease in the United States and the main reason for consulting the doctor and from school.

What causes colds?
Most colds are caused by rhinoviruses (the name comes from the Greek word rhin, meaning “nose”) that are in invisible droplets in the air we breathe or on things we touch. There are over 100 different rhinoviruses ability to penetrate the protective lining of the nose and throat, triggering an immune reaction can cause sore throat, headache, or your child make it difficult breathe through the nose.

Dry air-inside or out – can lower your child’s resistance to infections caused by viruses that cause colds. Smoking or being around a smoker has the same effect. Smokers are more likely to catch a cold than nonsmokers, and it is possible that symptoms are more severe, longer lasting and more likely to lead to bronchitis or even pneumonia.

But while the old stories say otherwise, no one has a cold for not wearing a jacket or sweater when fresh, for sitting or sleeping in a drafty place, or out with wet hair.

What are the symptoms my son?
The first symptoms of a cold are often a scratchy throat, runny or stuffy nose and sneezing. Perhaps children with colds also have a sore throat, cough, headache, mild fever, fatigue, muscle aches and appetite loss. The secretions from the nose of your child may change from watery to thick yellow or green.
