From United States Youth Soccer:

We suggest that one of the best measures local volunteers can take at this time is to urge all parents to exercise good judgment regarding attendance at practices and games.  If their US Youth Soccer player or another family member appears to have flu-like symptoms (fever, cough, sore throat, body aches, headaches, chills, fatigue), they should stay home and schedule an appointment with their primary care physician.

What You Can Do to Stay Healthy*
There are everyday actions people can take to stay healthy:

• Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
• Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleansers are also effective.
• Avoid touching your eyes, nose or mouth as germs spread that way.
• Try to avoid close contact with ill people.
• Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.
• If you get sick, CDC recommends that you stay home from work and limit contact with others to keep from infecting them.
