How can I prevent norovirus infection?

ANSWER

Good hygiene is the key to preventing a norovirus infection, especially when you are close to a lot of other people. Here are some specific tips:

If you have norovirus, don't prepare food for at least 2 to 3 days after you feel better -- and try not to eat food that has been prepared by someone else who is sick.

  • Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom or changing a baby's diaper, and before you prepare or eat food. Alcohol-based cleansers are not as effective as soap and water.
  • Carefully throw away any contaminated items (such as dirty diapers).
  • Wash raw fruits and vegetables thoroughly. Cook oysters and other shellfish before eating them.
  • Clean and disinfect surfaces with a mixture of detergent and chlorine bleach after someone gets sick.
