Norovirus describes a family of around 50 strains of virus that share one miserable conclusion: copious time in the bathroom. Annually, an estimated over half a billion persons across the globe contract it.

Norovirus is a form of infectious gastroenteritis, which is “a swelling of the intestines and the colon that often leads to diarrhea” as well as vomiting, as explained by a medical expert.

While it circulates year-round, it bears the nickname “winter vomiting bug” because its infections rise from December to early spring in the northern parts of the world.

Here is what you need to know.

How Does Norovirus Spread?

Norovirus is exceptionally infectious. Most often, it enters the gastrointestinal tract through tiny viral particles originating in an infected person's spit or feces. These particles may end up on your hands, or contaminate meals, eventually in your mouth – “known as fecal-oral transmission”.

The virus can stay infectious for up to 14 days upon non-porous surfaces like doorknobs or toilets, requiring very little amount to make you sick. “The infectious dose of this virus is under twenty viral particles.” In comparison, COVID-19 require roughly 100-400 virus particles for infection. “When a person, has an active norovirus infection, they shed countless numbers of virus particles for each gram of stool.”

There is also some risk of transmission through aerosolized particles, notably when you are around someone while they are experiencing symptoms such as severe diarrhea or vomiting.

Norovirus becomes infectious about 48 hours prior to the onset of illness, and people may stay contagious for several days or sometimes weeks once symptoms subside.

Confined spaces such as nursing homes, childcare centers and airports form a “ideal breeding ground for acquiring the infection”. Ocean liners are particularly bad history: health authorities note dozens of norovirus outbreaks aboard vessels on a regular basis.

What Are the Symptoms of Norovirus?

The beginning of symptoms often seems abrupt, starting with stomach cramps, sweating, shivering, nausea, vomiting along with “severe diarrhoea”. Most cases are considered “mild” in the medical sense, indicating they clear up in under 72 hours.

However, this is an extremely miserable illness. “Individuals often feel pretty wiped out; they may have a slight fever, headaches. In most cases, people are not able to continue doing their normal activities.”

Do I Need Medical Care Required for Norovirus?

Every year, the virus causes several hundred deaths as well as many thousands hospital stays in some countries, where people aged 65 and older facing the highest risk level. Those most likely to have serious norovirus are “young children under 5 years old, along with the elderly and those who are immunocompromised”.

Those in higher-risk age categories can also be especially susceptible to kidney injury due to severe fluid loss from profuse diarrhoea. If you or loved one is in a higher-risk age category and is unable to keep down liquids, medical advice recommends consulting a physician or visiting urgent care for intravenous hydration.

Most healthy adults and kids without chronic health issues get over the illness without hospital care. Although health agencies report thousands of outbreaks each year, the total number of infections is closer to many millions – the majority go unreported because people can “handle their infections at home”.

While there’s nothing you can do that cuts the length of an episode with norovirus, it’s vitally important to stay hydrated throughout. “Aim to drink an equivalent volume of sports drinks or water as you are losing.” “Crushed ice, ice lollies – really any fluid you can tolerated to keep you hydrated.”

Anti-nausea medication – a drug that prevents nausea and vomiting – like certain over-the-counter options could be needed if you cannot retain fluids. Do not, however, use medications for stopping diarrhea, including loperamide or bismuth subsalicylate. “Our body is trying to eliminate the virus, and should we keep it within … they stick around longer.”

How Can You Avoid Getting Norovirus?

At present, we don’t have a vaccine for norovirus. That’s because the virus is “notoriously hard” to grow and study in labs. It encompasses numerous strains, which mutate rapidly, rendering universal immunity challenging.

This makes fundamental hygiene.

Practice Thorough Handwashing:

“For preventing or control infections, proper hand hygiene is vital for all.” “Importantly, infected individuals must not prepare food, or care for other people when they are sick.”

Hand sanitizer and other alcohol-based disinfectants are ineffective on this particular virus, because of its viral makeup. “You can use hand sanitizers in addition to soap and water, sanitizer alone alone does not work well against norovirus and is not a replacement for washing with soap.”

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

Avoid Using an Infected Person's Bathroom:

Whenever feasible, set aside a separate bathroom for any sick person at home until after they are better, and limit other contact, is the advice.

Disinfect Contaminated Surfaces:

Clean surfaces using a bleach solution (one cup per gallon of water) alternatively undiluted 3% hydrogen peroxide, which {can kill|
