In brief: 5-10 days

The incubation period (time from contracting virus to time of symptoms) about 18-72 hours and viral shedding (contagious) start just around enset of symptoms or a bit before and continue for about 5-10 days.
Young children may shed for longer period of time. With appropriate treatment/med, shedding should stop in about 72 hours. Preention is key--vaccination & handwashing.. Good luck.

In brief: ...

It’s possible you can spread the flu to someone else the day before you start having symptoms and feel sick.
Most adults may be able to infect others up to 5-7 days after becoming sick. Young kids and people with weakened immune systems could possibly be able to spread the flu for an even longer time. Prevention is best by getting the flu shot every year and washing your hands often.
