Therefore, it is particularly important for people to use good hand washing and other hygienic practices after they have recently recovered from norovirus illness. A person can be infected with norovirus more than once. Although there is a short period of time likely a few months immediately following infection with Norovirus that a person is protected from reinfection, it is only a temporary protection. Strict hand washing after using the bathroom and before handling food items is important in preventing the spread of the virus, because it continues to be present in the stool for as long as two to three weeks after the person feels better.
One excellent way to prevent spreading the virus to others is daily wiping of doorknobs, faucets and commodes with a mild bleach solution made of one cup of bleach in nine cups of water. Care should be used to keep the solution off your skin and away from fabrics that may be damaged by the bleach. Family members should use separate hand towels for two to three weeks after symptoms go away.
People should keep in mind that the virus is easy to avoid with careful and frequent hand washing. Refrain from chewing on your fingernails, pencils or pens.
Don't even unwrap a piece of candy or gum without first washing your hands. Inability to retain sufficient fluids is the most critical concern, especially with young children.
Monitor fluid intake and output, and seek immediate medical care to prevent complications from dehydration. Skip to main content. Close this alert. Home Current Page. What is gastroenteritis?
