What is Norovirus?
Norovirus is the leading cause of foodborne illness in the United States, responsible for 58% of such infections acquired in the country each year, according to the Centers for Disease Control and Prevention (CDC).
Norovirus infections are caused by a group of viruses that spread easily, with as few as 10 viral particles having the ability to make someone sick, health experts say.
There are about 2,500 norovirus outbreaks reported annually in the United States. The outbreaks can occur throughout the year but are most common from November to April.
Symptoms
Along with vomiting and diarrhea, common symptoms include nausea, stomach pain, body ache, headache, and fever.
How Do You Get It?
Most norovirus outbreaks occur when people who are already infected spread the virus to others by direct means, such as through sharing food or eating utensils. Outbreaks can also be spread through food, water, or contaminated surfaces.
How Long Do You Stay Sick?
Illness caused by norovirus typically starts suddenly, with symptoms developing 12 to 48 hours following exposure to the virus. Most people get better within one to three days and recover fully.
However, norovirus nevertheless causes on average 900 deaths and 109,000 hospitalizations annually, mostly among adults aged 65 and older. It also leads to 465,000 emergency department visits, mostly involving young children.
Who’s at Risk?
People of all ages can get infected and fall sick from norovirus. Young children, older people, and those with weakened immune systems are most at risk, with dehydration from vomiting and diarrhea the top concern.
There is no medication to treat norovirus. Rehydration is recommended by drinking water and other liquids, with the exception of coffee, tea, and alcohol.
How Can I Protect Myself?
Rigorous and frequent handwashing is the best defense against norovirus during the peak winter season, scrubbing the hands with soap and warm water for 20 seconds before meals.
Scrubbing surfaces with household disinfectants can also help.
Conclusion
Norovirus is a highly contagious virus that causes vomiting and diarrhea. It is essential to take precautions to prevent the spread of the virus, especially during the peak winter season. By following proper hygiene practices, such as frequent handwashing and scrubbing surfaces, you can reduce your risk of getting infected.
