How is common cold spread?
With an estimated 1 billion cases of the common cold in the United States each year, it is important to know how the common cold is spread, according to the National Institute of Allergy and Infectious Diseases, or NIAID. According to MayoClinic.com, the common cold is an upper-respiratory infection that could be any of roughly 200 different viruses. Kids are more prone to catching a cold, about 10 a year, while adults catch around two to four annually. Knowing how the common cold is spread will help prevent the spread of the viruses.
