Common Cold - Causes, Symptoms And Treatment
The common cold is an infection of the upper respiratory tract caused by a virus. Cold weather does not cause colds, although most colds are caught in the fall and winter. This is because most cold viruses thrive better in colder temperatures, when there is less humidity in the atmosphere. There are over 200 viruses that can cause the common cold, an infection of the upper respiratory tract, but the most common ones are rhinoviruses.
Common cold symptoms
Symptoms of the common cold usually begin two to three days after infection and often starts with nasal discharge and obstruction of nasal breathing.
Causes of common cold
Most colds are caused by rhinoviruses (the name comes from "rhin," the Greek word for nose) that are in invisible droplets in the air we breathe or on things we touch. More than 100 different rhinoviruses can infiltrate the protective lining of the nose and throat, triggering an immune system reaction that can make your child's throat sore, his or her head ache, and can make it hard for your child to breathe through the nose.
The common cold is transmitted through person-to-person contact, typically when an infected person touches the eyes, mouth, or inside of the nose and spreads the virus to the hands. Poor hygiene promotes infection. It is estimated that healthy adults get an average of two colds per year. Children generally get many more because their immune systems are immature, and they have not yet developed immunity to many of the viruses that cause colds.

Are common cold contagious?
Common cold are the most contagious during the first 2 to 4 days after symptoms appear, and your child may be contagious for up to 3 weeks. Your child can catch a cold by breathing in virus particles spread through the air by sneezing or coughing or from person-to-person contact. The viruses are easily transmitted through contact with the secretions of infected people (e.g., handshakes, shared objects, kissing).
