A stomach bug.
  Everyday I,
  Wash my hands after using the toilet & coming in from outside, I sanitize my hands at school before eating. When I come home from school I wash my hands again before having a snack & removing my contact lenses.Am I at low risk? Really don't want to catch it.
  PS, can you catch a bug if no one at home/school has it? Many thanks, louise.
