How Common Cold Develops

A common cold is a viral infection of your nose and throat (upper respiratory tract). It’s usually harmless, although it might not feel that way. Many types of viruses can cause a common cold. These viruses can be spread through the air, personal contact, and respiratory secretions — things such as a handshake, touching contaminated objects, and exposure to an infected person’s sneezes or coughs.

A cold virus is deposited into the front of the nasal passages by contaminated fingers or by droplets from coughs and sneezes. Small doses of virus (1-30 particles) are sufficient to produce infection. The virus is then transported to the back of the nose and onto the adenoid area by the nose itself!

Although many types of viruses can cause a common cold, rhinoviruses are the most common culprit. A cold virus enters your body through your mouth, eyes or nose. The virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks.

It also spreads by hand-to-hand contact with someone who has a cold or by sharing contaminated objects, such as utensils, towels, toys or telephones. If you touch your eyes, nose or mouth after such contact or exposure, you’re likely to catch a cold.
