When you have the flu when are you most contagious?

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.

Moreover, how long is a person contagious with the flu while taking Tamiflu?

CDC guidelines recommend droplet precautions for seven days after illness onset or until 24 hours after the resolution of fever and respiratory symptoms, whichever is longer, and the fact that Tamiflu is being used does not change that.

How long does it take for Tamiflu to be effective?

Both adults and children may notice an improvement in their symptoms within two days of taking Tamiflu. However, Tamiflu only works if taken as directed, which means you must take Tamiflu within two days of noticing symptoms.
