Q: The Flu Is Contagious. Most healthy adults may be able to infect other people beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Children may pass the virus for longer than 7 days. Symptoms start 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. During this time, those persons may still spread the virus to others. The lymph nodes can swell making turning the head painful. The eyes can be sensitive to light. There can be a dry annoying cough. The flu is also contagious the day before the first symptoms begin. The person remains contagious for 5 to 7 days, as long as the body is producing new mucus, and they are also contagious as long as they have a fever. The Flu Is Contagious Most healthy adults may be able to infect other people beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Children may pass the virus for longer than 7 days. But just because you don't exhibit these symptoms, it doesn't mean you don't have the flu, researchers say. And you could be just as contagious. In fact, their study found that roughly three-quarters of people with seasonal or pandemic flu show either no symptoms or mild ones that aren't usually linked to flu. People with flu can spread it to others up to about 6 feet away. Most experts think that flu viruses are spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth or nose. Even If You Don't Have Symptoms, You May Still Have The Flu : Shots - Health News Roughly 1 in 5 unvaccinated people had the flu between 2006 and 2011, but only a quarter of them had symptoms, a study found. If you have already been exposed to the flu, but you don't have any symptoms, you can take Tamiflu for up to 6 weeks to help prevent you from getting sick. People often mistake the flu for the common cold, Hayward tells Shots. A lot of the time you may just have a runny nose, a bit of a cough, perhaps a sore throat, he says. But the classic flu symptoms of a sudden fever and muscle aches the study shows that that very often doesn't happen. And it's often a much more mild illness. Influenza's incubation period is 1-4 days with 2 days being the most common for showing symptoms. There are many viruses that cause cold and flu symptoms that are not the common cold or influenza. If you were exposed to one of those it may take up to 7 days before symptoms appear.
