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.
With some viruses, you're contagious for as long as you have symptoms or even beyond. With others, you continue to have symptoms after youâre no longer contagious. Adults who have the flu are contagious for five days after first developing symptoms, while kids can stay contagious even longer. If you have a cold, you're most likely to give it to someone else during the first few days of having a runny nose, sneezing, and coughing.
