An understanding of how viruses evolve and how they adapt to new hosts and their immune systems is important, especially if we are to prepare for new, potentially pandemic diseases.

To catch a cold, your child must come in contact with someone who is infected with one of the cold viruses. The cold virus can be spread:. Through the air. If a person with a cold sneezes or coughs, small amounts of the virus can go into the air. By direct contact. This means that your child touches an infected person. A cold is easy for children to spread.
This can spread the virus. All children are at risk for the common cold. They are more likely than adults to get a cold.
Here are some reasons why:. Less resistance. Winter season. Most respiratory illnesses happen in fall and winter, when children are indoors and around more germs. The humidity also drops during this season. This makes the passages in the nose drier and at greater risk for infection. Hand-to-mouth contact. Children are likely to touch their eyes, nose, or mouth without washing their hands.
This is the most common way germs are spread. Cold symptoms start from 1 to 3 days after your child has been in contact with the cold virus.
