How does flu spread?
Flu viruses are thought to spread mainly by droplets made
when someone with flu coughs, sneezes or talks. These
droplets can land in the mouths or noses of people nearby.
A person also can get flu by touching something that has flu
virus on it and then touching their mouth, eyes, or nose. People infected with flu may be able to infect others beginning 1 day before symptoms develop and up to 5-7 days after becoming sick. That means you may be able to spread flu to someone else before you know you are sick as well as while you are sick.
When can my child go back to school after having flu?
Keep your child home from school, day care, or camp for at
least 24 hours after their fever is gone. (The fever should be
gone without the use of a fever-reducing medicine.) A fever
is defined as 100°F (37.8°C) or higher.
