How is the common cold spread?

The common cold is a highly contagious respiratory illness that is spread through contact with an infected person or through contact with surfaces or objects that have been contaminated with the virus. The virus can be transmitted through the air when an infected person coughs, sneezes, or talks. It can also be transmitted through direct contact with an infected person, such as through kissing or shaking hands, or through contact with objects or surfaces that have been contaminated with the virus, such as doorknobs, countertops, or toys.
