The contagious period for the flu begins about 1 day before symptoms start and can last as long as 5-7 days from when you first felt sick. You're generally contagious with a cold 1-2 days before your symptoms start, and you could be contagious as long as your symptoms are present—in rare cases, up to 2 weeks.

You're contagious before you have symptoms — during the incubation period, when the virus enters your system. And just because you feel better doesn't mean those around you are safe. In fact, you're still contagious after symptoms subside, carrying a bacterial or viral infection that can spread to others.

Symptoms of a cold can be felt about one to four 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 the most contagious, so it's best to stay home and rest.

It's usually not contagious, so you typically can't get it from another person or pass it onto someone else. People with this condition often have a phlegmy cough, but even if you are in close contact with them when they are coughing, if the illness is not caused by infection, you won't catch it.

Symptoms can begin about 2 days (but can range from 1 to 4 days) after the virus enters the body. That means that you may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Some people can be infected with the flu virus but have no symptoms.

Good hygiene. Although chest infections generally aren't as contagious as other common infections, like flu, you can pass them on to others through coughing and sneezing. Therefore, it's important to cover your mouth when you cough or sneeze, and to wash your hands regularly.
