What Causes The Runny Nose in Children?

Runny nose is a disease happening frequently in children. This disease happens when an overabundance of fluid or mucous triggered by irritated nasal tissues and blood vessels exits the nose or drains from the nose into the throat. There are many reasons can lead to a runny nose in a child.

The common cold

This is the most typical cause of a runny nose and a chronic runny nose. This is usually a mild illness, and the child feels and looks well normally. Children with the common cold usually get better on their own around a week. The runny nose is usually followed by a mild fever. There could also be other symptoms such as sore throat, headache, coughing, watery eyes, sneezing, and fatigue.


Allergies are also a common cause of runny nose. They usually appears after 2 years of ages and after the child has had a lot of irritation to allergens (the substances that can produce allergic reaction in the body). They might happen during a particular season or after a particular exposure-for example, after being around grass or animals. The symptoms often seen with are watery and itchy eyes, asthma, sneezing, rubbing of the nose and a lot of clear mucus. One special thing, with allergies, the runny nose may not last for weeks or months and it seldom has a fever or can not spread disease to other people.

Bacterial infection

This is a kind of continuous illness, known as sinus infection.  Young children with sinusitis may have some or all of these symptoms: a runny nose lasting for a long time more than 10 to 14 days that may be clear or thick and green or yellow, postnasal drip, foul smelling breath, a daytime cough which might worsen at night, and swelling around the eyes. Remember that yellow or green mucus does not always mean that a child has a bacterial infection. It is normal for the mucus to get thick and change color as the common viral cold progresses.
