Људи у ризику 

•  Млада деца : Most children have a first cold before the age of 1 and remain particularly vulnerable until they are 6 years old, due to the immaturity of their immune system. The fact that they are in contact with other children (in kindergarten, daycare or nursery) also increases their risk of catching colds. With age, colds become less common.
• People whose immune system is weakened by medication or illness. In addition, the symptoms are more pronounced in these people.

Фактори ризика

• The stress. A meta-analysis of 27 prospective studies confirmed that stress was a very significant risk factor⁶¹.
• Smoking. Cigarettes produce a local irritant effect on the respiratory tract which decreases the local defenses and weakens the immune system.⁶².
• A recent plane trip is a possible risk factor. A questionnaire was administered to 1100 passengers on flights between San Francisco and Denver, Colorado. One in 5, 20%, reported having a cold within 5-7 days after the theft. Whether or not the air was recirculated in the cabin had no effect on the incidence of colds⁶³.
• Practice intense physical exercises. Athletes who train excessively are more prone to colds.
