The Origin of Allergies or Cold

The words allergies and cold have interesting histories.

The word allergy comes from Greek. It was first used by the Austrian doctor Clemens von Pirquet in 1906. The term combines two Greek words:

allos ; meaning “different”
ergon ; meaning “reaction”

So the word allergy means a different or unusual reaction by the immune system.

The word cold has been used for centuries to describe respiratory infections. In the past, people believed cold weather caused illness. That is why the infection became known as the common cold.

Over time, medical science discovered that colds are actually caused by viruses, especially rhinoviruses.
