How You Get Infected
Contrary to popular belief, a cold is not caused by cold weather. It is caused by viruses transmitted through the air and close contact with the cold sufferer.
How Viruses Spread
They get inhaled through the nose and attach to the nasal lining where they multiply and spread.
What It Leads To
The viruses invade healthy cells in the nasal passages and cause symptoms such as stuffy and runny nose, sore throat, coughing, aches and pains, and fever.
