Question

Why do some people get sick with the common cold more frequently than the others?​

Answer 1

Answer:

Our genetic make-up determines our immune system and immune deficiencies are an important contributory factor in why some people contract more colds than others. A genetic weakness in the lungs, such as cystic fibrosis for example, can put people at risk if they just catch a common cold.

Answer 2

People get common cold due to the changes in atmosphere but the reason why some get caught by it very easily is because of their week immune system.
