A cold is typically acquired by touching one's eyes or nose after touching surfaces with cold germs on them, or by inhaling the germs. Symptoms usually begin 2 or 3 days after infection and last 2 to 14 days. Colds can be avoided by frequent handwashing and by staying away from infected individuals. | A cold is typically acquired by touching one's eyes or nose after touching surfaces with cold germs on them, or by inhaling the germs.
