The norovirus identifies a family of about 50 viral strains that all lead to one uncomfortable outcome: extended time in the the bathroom. Each year, some over half a billion persons worldwide are infected by this illness.

This virus is a form of infectious gastroenteritis, which is “irritation of the bowel and the colon that often leads to loose stools” and vomiting, as explained by a medical expert.

Norovirus circulates year-round, it has earned the nickname “winter vomiting bug” because its activity surge between December to early spring in the northern hemisphere.

Here is what you need to understand.

How Does Norovirus Propagate?

This pathogen is extremely transmissible. Usually, the virus invades the digestive system by way of tiny virus particles from an infected person's saliva or stool. These germs may end up on hands, or contaminate meals, and ultimately in your mouth – “what we call the fecal-oral route”.

Particles remain viable for as long as 14 days upon non-porous surfaces like doorknobs or faucets, with only an extremely small amount to make you sick. “The required exposure of this virus is under twenty particles.” By contrast, COVID-19 typically need roughly one to four hundred particles to infect. “When somebody, is suffering from norovirus infection, they shed countless numbers of virus particles in every gram of feces.”

One must also consider the possibility of spread through particles in the air, notably when you are near someone while they are experiencing active symptoms such as diarrhea or being sick.

A person becomes infectious approximately two days prior to the start of illness, and people may stay infectious for several days or sometimes a few weeks after symptoms subside.

Close quarters including nursing homes, childcare centers and travel hubs create a “prime location for spreading the infection”. Cruise ships have a notorious history: health authorities track numerous norovirus outbreaks on ships annually.

Which Are the Symptoms of Norovirus?

The onset of symptoms can feel rapid, initially involving stomach cramps, perspiration, chills, queasiness, vomiting along with “severe diarrhea”. Typically, the illness are “moderate” clinically speaking, which means they resolve within 72 hours.

However, this is a remarkably debilitating illness. “People may feel very fatigued; experiencing a low-grade fever, headaches. And in most cases, people are unable to continue doing daily tasks.”

Do I Need Medical Care Required for Norovirus?

Every year, the virus leads to several hundred deaths as well as tens of thousands of hospitalizations in some countries, where people the elderly facing the highest risk level. Those at greatest risk of experiencing severe infections are “young children less than five years old, and especially older individuals and people who are with weakened immune systems”.

People in these vulnerable age groups are also particularly at risk of kidney injury from dehydration caused by excessive diarrhoea. If you or loved one falls into a vulnerable group and cannot retain fluids, medical advice suggests consulting a physician or visiting a local emergency department for IV fluids.

The vast majority of adults and kids with no chronic health issues recover from the illness without hospital care. While authorities track thousands of norovirus outbreaks annually, the true figure of cases reaches millions – most cases are not reported since people are able to “manage their illness on their own”.

Although there is nothing one can do to reduce the length of a bout of norovirus, it’s vitally important to remain hydrated throughout. “Try drinking an equivalent volume of fluids like sports drinks or plain water as that comes out.” “Crushed ice, popsicles – essentially anything that can be keep down to maintain hydration.”

An antiemetic – a drug that prevents nausea and vomiting – such as Dramamine might be necessary if you cannot keep liquids down. Do not, however, take medications that stop diarrhea, including loperamide or bismuth subsalicylate. “The body is trying to eliminate the virus, and if we keep the viruses inside … they stick around longer.”

What are Ways to Avoid Getting Norovirus?

Right now, we don’t have a vaccine for norovirus. This is due to the fact norovirus is “very challenging” to grow and research in labs. The virus has many strains, mutating often, rendering a single vaccine challenging.

Therefore, prevention relies on the basics.

Practice Thorough Handwashing:

“To prevent or control outbreaks, proper hand hygiene is vital for all.” “Critically, infected individuals should not prepare food, or care for other people when they are ill.”

Hand sanitizer and other alcohol-based disinfectants do not work on norovirus, due to its structure. “You can use sanitizer in addition to handwashing, but hand sanitizer is not sufficient against it and is not a replacement for washing with soap.”

Wash your hands often well, using soap, for a minimum of twenty seconds.

Avoid Using an Infected Person's Bathroom:

If possible, designate a different restroom for any sick person at home until after they recover, and minimize close contact, is the advice.

Disinfect Contaminated Surfaces:

Clean surfaces using a bleach solution (one cup per gallon of water) alternatively undiluted three percent hydrogen peroxide, both of which {can kill|
