Norovirus (cont.)

What Are Medical Treatments for a Norovirus Infection?

People with severe nausea and vomiting are often given medicine (for example, promethazine, prochlorperazine, or ondansetron) intravenously to reduce or stop vomiting. If this is effective, patients may later receive oral or rectal preparations of these drugs and monitored in the clinic by their physician. Individuals who become dehydrated may require intravenous fluids with electrolytes to avoid complications of dehydration. A few severely dehydrated patients may require hospitalization until their fluids and electrolytes are replenished.

Follow-up for Norovirus Infections

If the symptoms listed above for norovirus infection persist longer than three days or the person becomes dehydrated, medical help should be sought. Patients who are immunosuppressed, infants, and the elderly should follow up with their doctor to avoid getting dehydrated.

People with norovirus infection should not return to work until about three days after all symptoms have resolved. Strict hygiene with good hand washing needs to be emphasized for these individuals, as some people shed virus in their feces for two weeks after symptoms resolve.

A bland diet is recommended for children and adults as the symptoms of the norovirus infection diminish. Food items such as rice, bread, bananas, applesauce, pasta, and clear fluids are suggested.

What Is the Prognosis of a Norovirus Infection?

Norovirus infection typically resolves on its own without any adverse consequences in healthy people who receive adequate hydration and the prognosis is generally excellent. People with suppressed immune function, the elderly, or those with chronic medical conditions may have a higher risk of complications from the infection.
