Symptoms of a cold may appear between two and five days after exposure to and infection with the virus. People are most contagious for the first two to three days of a cold. A cold is most often not contagious after the first week. Colds can spread very quickly. After the symptoms are present, people can transmit the virus as long as their body is still producing mucus. During this period, anything people with a cold touch can also become infected with germs. Because a cold is caused by a virus, antibiotics will not help.
