Many children get nervous about school and about getting sick. For most of them, it's just a phase. With patience and encouragement they get through it.

Here are some ideas that might help you and your son:

• Talk to your child
  Make sure you understand everything as best you can. Did something happen at school? Worrying about getting sick might not be the real reason. If he's really worried about getting sick, try to understand why. Did someone he knows get very sick or die? Understanding exactly what he's thinking can help you help him.
• Talk to his teacher
  His teacher can give you more information and help decrease your child's anxiety while he's at school.
• Talk to your son about ways to keep him healthy
  Washing his hands can make a big difference. Buy him some alcohol-based hand sanitizer to carry with him. A healthy diet, plenty of exercise, and an early bedtime can also make a difference.
• Let your son know that if he gets sick you will take care of him
  Help him understand that most sick people get completely better.

If none of this makes a difference, your child may need to see a mental health professional. This doesn't mean he's crazy or you've done anything wrong. Sometimes all of us need help. Getting help will make your son feel better faster. Talk to your doctor about who would be the best person for your child.
