Here’s some guidelines on how long you should stay home:
How long to stay to home
The Centers for Disease Control and Prevention recommends that you stay home for at least 24 hours after your fever is gone, except to get medical care or other necessities. Your fever should be gone for at least 24 hours without the use of a fever-reducing medicine, such as Tylenol. You should stay home from work, school, travel, shopping, social events, and public gatherings.
Check with your child's daycare or school before sending your child back. Many have rules and it’s generally at least a full day after they don't have any fever without medication.
In general, about a week. People with the flu may be able to infect others from 1 day before getting sick to 5 to 7 days after. However, children and people with weakened immune systems can infect others for longer periods of time, especially if they still have symptoms.
What should you do while while sick:
Stay away from others as much as possible to keep from infecting them. If you must leave home, for example to get medical care, wear a face mask if you have one, or cover coughs and sneezes with a tissue. Wash your hands often to keep from spreading flu to others.
