The Killeen Independent School District is in the midst of dealing with flu season among students and staff.
The district has released a list of precautions so parents can work with teachers to make sure students stay healthy and well.
At school, students and staff are being encouraged to wash hands often, use hand sanitizes and cough or sneeze into elbows or sleeves, or use a tissue.
Parents can help by keeping students home if they are ill and not allowing them to return until they have been fever-free for 24 hours.
Flu symptoms can include a new cough and fever, sore throat, headache, muscle aches, joint paint, weakness or extreme fatigue.
KISD had 124 students out last week with flu, according to Terry Abbott, chief communications officer. There have been 146 cases of flu reported in the district since December.
