¿What is a cold? What does catch a cold mean?

Did you know that each year millions and millions of people catch a cold? Why? Now we'll explain it to you.

When we talk of colds we are talking about a VIRUS.

A virus is a microscopic infectious agent (in other words, it is very tiny).

Colds in fact are produced by more than 100 different types of viruses that invade people through the airways (nose and mouth).

The most commonly involved viruses are known as rhinoviruses and coronaviruses.
