Besides a runny nose and a terrible accent
The common cold is caused by any of the 200 viruses spread by person-to-person contact or via the air. The most common include rhinoviruses and adenoviruses. In 40% of the cases, however, no agent is identified. However, drugs that suppress the immune system can make a person more susceptible to infectious conditions, including the common cold.
Cold weather does not cause the common cold. It may, however, increase the frequency and level of risk of infection.
Being present in public places over an extended period of time. Children attending school most often contract colds this way.
Another household member with a cold (extremely contagious).
Crowded and/or unsanitary living conditions. This type of environment is conducive to harvesting cold viruses, and contaminated items facilitate the spread of the virus.
Direct contact with infected individuals. The common cold spreads through simple touch, such as kissing or merely shaking hands.
Stress, fatigue, and/or allergic disorders. These weaken the immune response and expedite infection.
Certain conditions that resemble the cold and can make you think you have one.
- The flu, another highly contagious viral infection.
- Epstein-Barr virus
- Seasonal allergies
