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.
The cold and flu season lasts from September until May, but catching a cold has nothing to do with the temperature outside. The reason colds are so contagious has more to do with the amount of time people spend inside in close contact with each other. What Is a Contagious Cold? The common, contagious cold is a brief, mild illness. The early symptoms of headache, sneezing, chills, and sore throat start two to three days after you have been infected. The symptoms of nasal discharge and congestion increase quickly and then go away after about a week.
