A cold is an upper respiratory infection characterized by a combination of coughing, sneezing, congestion, runny nose, headache, and/or sore throat. It is caused by one of a multitude of viruses and is very contagious. The period of contagiousness actually starts a day or two before you even feel sick. The most contagious period is when the virus first enters into your body and starts to make copies of itself. This is because your immune system has not yet had time to fight back. This period of maximum contagiousness lasts about 3 to 4 days and is when you are suffering the most. After this time your immune system starts to fight back and the viral level slowly drops and you become less and less contagious.
Most of the time you become contagious about One to three days after contracting the flu and stay contagious for up to 5 days after onset of symptoms. However, children and adults with weakened immune symptoms can be contagious to those around them up to 14 days. For colds, most people are contagious for a day before symptoms appear and remain contagious for up to 5-7 days. In rare cases, children can pass a cold for up 14 days. A cold is also known as an upper respiratory infection.
