What is a cold?

We use the term cold to refer to a group of very frequent ailments caused by one or several viruses.

We could, in fact, say that a cold is a minor infection of viral origin which generally affects the respiratory tract, that is, the nose and throat. Sometimes, however, the infection can spread to the trachea and the bronchi.

In principle, a cold is nothing more than that and usually lasts between three and seven days.

However, care must be taken when whoever has caught the cold is a small child, a pregnant woman or an elderly person, because a cold can open the door to other, more serious conditions.

When you catch a cold, up to a hundred viruses could be responsible, although the most usual ones are the rhinoviruses and coronaviruses.
