Noroviruses are the most common cause of gastroenteritis in the United States,
affecting more than 20 million people each year. Infection with a norovirus can cause
nausea, vomiting, diarrhea,
stomach cramps, fatigue, and mild fever.
Noroviruses are highly contagious and often spread quickly in crowded, closed places
like cruise ships, childcare centers, schools, and nursing homes. Noroviruses are
spread through the vomit and feces of infected individuals. People can become infected
with a norovirus by eating contaminated food, drinking contaminated water, or coming
into contact with infected people or objects.
There is no specific treatment for norovirus infection. Although the condition
is rarely serious, it can cause dehydration,
which can lead to serious complications, especially in young children, the elderly,
and people with weakened immune systems.
Keep in Mind
In most cases, norovirus infections will get better in a few days without treatment.
People infected with a norovirus should make sure to drink plenty of fluids to prevent
hands well and often can help stop the spread of noroviruses.
