Reason

Although many viruses can cause the common cold, rhinovirus is the most common culprit.

Cold viruses enter your body By means of your mouth, eyes, or nose. The virus can be spread through droplets that are released into the air when an infected person coughs, sneezes, or talks.

It is also spread by hand contact with someone who has a cold or by sharing contaminated objects, such as utensils, towels, toys, or phones. If you touch your eyes, nose, or mouth after such contact or exposure, you may catch a cold.

Risk factors

The following factors can increase your chances of catching a cold:

Age: Children under 6 are most at risk of catching a cold, especially if they spend time caring for children.
Weakened immune system: Having a chronic illness or weakened immune system increases your risk of getting sick.
Time of year: Both children and adults are more susceptible to colds in the fall and winter, but of course you can catch a cold at any time.
Smoking: You’re more likely to catch colds and get worse if you’re exposed to second hand smoke.
Exposure: If you are around a lot of people, such as at school or on an airplane, you may be at increased risk of being exposed to the virus that causes colds.
Complications
Acute ear infection (otitis media). This happens when bacteria or viruses get into the space behind the eardrum. Typical signs and symptoms include ear pain and, in some cases, a green or yellow runny nose or a fever that returns after the common cold.
Asthma. Colds can trigger an asthma attack.
Acute sinusitis. In adults or children, an unresolved common cold can lead to inflammation and infection of the sinuses (sinusitis).
Other secondary infections. These include strep throat (streptococcal pharyngitis), pneumonia, and pneumonia or bronchiolitis in children.

Prevent

There is no vaccine for the common cold, but you can take general precautions to slow the spread of cold viruses:

Wash hands: Wash your hands well and often with soap and water, and teach your children the importance of hand washing.

Use a tissue: Sneeze and cough into a tissue. Throw away used tissues immediately, then wash your hands carefully.
Teach your child to sneeze or cough into the bend of his elbow when he doesn’t have a tissue.

Do not share: Do not share cups or drinking utensils with other family members. Use your own glass when you or someone else is sick. Write the name of the person who has a cold on a cup or glass.
