How to Help Prevent the Spread of Norovirus

Advice from our experts

Here are some tips to help prevent the spread of norovirus in your home.

Norovirus causes inflammation of the stomach, intestines or both. Common symptoms include diarrhea, vomiting, nausea and stomach pain. A person usually develops symptoms 12 to 48 hours after being exposed to norovirus. Most people with norovirus illness get better within 1 to 3 days.¹

Unfortunately, the spread of norovirus can happen quickly. It’s highly contagious and can infect anyone. According to the Centers for Disease Control and Prevention (CDC), there is no vaccine for norovirus, so taking measures to help prevent the spread of the virus is important.²

Prevention can start with simple cleaning measures at home, including the use of a disinfecting bleach to help disinfect surfaces at home. The CDC recommends disinfecting hard, nonporous surfaces with a U.S. Environmental Protection Agency (EPA)-registered disinfectant that is approved to kill norovirus, such as Clorox® Regular Bleach₂
