• Check with your healthcare provider first, especially if you:

  • Have a weakened immune system

  • Have other health conditions

  • Still don't feel fully recovered

After Ending Isolation

For five days after ending isolation, you should:

• Wear a well-fitting mask when around others

• Wash your hands frequently

• Try to keep some distance from other people when possible

Important Tips

• Stay home during your isolation period to avoid spreading the flu to others

• Cover your coughs and sneezes with a tissue or your elbow

• Wash your hands often with soap and water

• Take extra care to avoid contact with:

  • Elderly people

  • Young children

  • People with weakened immune systems

Note: Some people, especially those with weakened immune systems, might need to stay isolated longer. Always follow your healthcare provider's specific advice for your situation.

This guidance helps ensure you can return to your normal activities while keeping others safe from getting the flu.
