Norovirus Infections Surging in the US
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.
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.
Symptoms
Illness caused by norovirus typically starts suddenly, with symptoms developing 12 to 48 hours following exposure to the virus. Common symptoms include:
- Sudden vomiting and diarrhea
- Nausea
- Stomach pain
- Body ache
- Headache
- Fever
How Long Do You Stay Sick?
Most people get better within one to three days and recover fully. However, norovirus can lead to dehydration, which can be life-threatening, especially in vulnerable populations such as young children, older adults, and people with weakened immune systems.
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.
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 and widespread illness that can cause severe symptoms and even lead to dehydration and hospitalization. By understanding how the virus is spread, recognizing the symptoms, and taking steps to prevent infection, you can protect yourself and your loved ones from the risks associated with norovirus.
