Cases of a Wretched Stomach Bug Surge in the United States
Cases of norovirus are surging in parts of the United States this winter, according to government data. The most recent numbers from the U.S. Centers for Disease Control and Prevention show there were 91 outbreaks of norovirus reported during the week of December 5, up from 69 outbreaks the last week of November. Numbers from the past few years show a maximum of 65 outbreaks reported during that first week of December.
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 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.
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.
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 common and highly contagious illness that can cause severe dehydration, especially in vulnerable populations. By understanding the causes, symptoms, and prevention methods, individuals can take steps to protect themselves and their loved ones from this wretched stomach bug.
