Symptoms of a cold can be felt about 1-4 days after catching a cold virus. They start with a burning feeling in the nose or throat, followed by sneezing, a runny nose, and a feeling of being tired and unwell. This is the period when you are most contagious -- you can pass the cold to others -- so it's best to stay home and rest. For the first few days, the nose teems with watery nasal secretions. Later, these become thicker and darker. You may get a mild cough.
