In addition, people may experience a low-grade fever, chills, headache, muscle aches, and fatigue. In most people, the illness is self-limiting with symptoms lasting for one to two days.

According to MDCH, norovirus is transmitted through touching virus-contaminated surfaces and objects, eating or drinking contaminated food, or by direct person-to-person contact.

It is highly transmittable and hand sanitizers are not effective against the virus. Good personal hygiene, including frequent hand washing with warm, soapy water for 20 seconds is crucial to preventing the spread of the disease.
