The norovirus refers to a family of approximately fifty strains of virus that all lead to one uncomfortable result: significant periods spent in bathroom. Each year, an estimated over half a billion persons across the globe contract it.

This virus is a form of viral stomach flu, which is “irritation of the bowel and the large intestine that triggers diarrhea” and vomiting, according to an infectious disease physician.

Although it can spread in all seasons, it has earned the label “winter vomiting bug” because its cases peak from December and February in the northern parts of the world.

Here is essential details to understand.

How Does Norovirus Transmit?

Norovirus is highly infectious. Typically, it invades the digestive system through minute viral particles originating in an infected person's spit or stool. These germs can land on surfaces, or in food and beverages, and ultimately in your mouth – “termed fecal-oral transmission”.

The virus can stay infectious for about 14 days on hard surfaces such as doorknobs and toilets, requiring a minuscule exposure to make you sick. “The infectious dose of noroviruses is fewer than 20 viral particles.” In comparison, other viruses like Covid-19 typically need about one to four hundred virus particles for infection. “During infection, is suffering from the illness, there’s billions of the virus for each gram of feces.”

There is also some risk of transmission through particles in the air, particularly when you are around an individual while they have active symptoms like diarrhea or being sick.

A person becomes infectious approximately 48 hours before the beginning of symptoms, and individuals can remain infectious for several days or even a few weeks once they’re feeling better.

Crowded environments such as nursing homes, daycares and airports create a “prime location for spreading the infection”. Cruise ships have a bad history: health authorities track dozens of norovirus outbreaks on ships on a regular basis.

Tell-Tale Signs of Norovirus?

The start of norovirus symptoms often seems sudden, initially involving stomach cramps, sweating, shivering, nausea, vomiting and “profuse diarrhea”. Typically, the illness are considered “moderate” from a medical standpoint, which means they subside within three days.

However, it’s a very debilitating illness. “Individuals may feel pretty wiped out; experiencing a low-grade fever, headache. In many instances, people are not able to perform daily tasks.”

Do I Need Medical Care Required for Norovirus?

Each year, norovirus is responsible for hundreds of deaths as well as many thousands hospital stays in some countries, with individuals the elderly at greatest risk level. Those at greatest risk of experiencing serious norovirus include “children under five years old, and especially older individuals and people that are immunocompromised”.

Those in higher-risk age categories can also be particularly susceptible to kidney problems from dehydration caused by excessive diarrhea. If you or a family member is in a higher-risk age category and unable to keep down fluids, experts recommends seeing your doctor or visiting urgent care for fluids via IV.

Most adults and kids without chronic health issues get over norovirus with no need for doctor visits. Although health agencies track thousands of outbreaks each year, the true number of cases is closer to many millions – most cases go unreported since people are able to “deal with their infections at home”.

While there’s no specific treatment you can do to reduce the duration of an episode of norovirus, it’s crucial to stay well-hydrated the entire time. “Aim to drink the same amount of fluids like electrolyte solutions or water as the volume that comes out.” “Ice chips, popsicles – essentially any fluid that can be tolerated to maintain hydration.”

Anti-nausea medication – medication that reduces queasiness and vomiting – like certain over-the-counter options could be required in cases where one can’t keep liquids down. Do not, however, take medicines for stopping diarrhea, like loperamide or bismuth subsalicylate. “Our body is trying to eliminate the virus, and if we keep it within … they persist for longer periods of time.”

How Can You Avoid Getting Norovirus?

Currently, we don’t have a vaccine for norovirus. That’s because the virus is “very challenging” to grow and research in laboratory settings. The virus has many strains, mutating rapidly, rendering a single vaccine challenging.

Therefore, prevention relies on the basics.

Practice Thorough Handwashing:

“For preventing or control infections, proper hand hygiene is important for everyone.” “Importantly, infected individuals must not prepare food, or care for others when they are sick.”

Hand sanitizer and similar sanitizers do not work against norovirus, because of its structure. “While you may use sanitizer along with handwashing, sanitizer alone alone does not work well against norovirus and cannot serve as a substitute for washing with soap.”

Clean hands frequently well, using good-quality soap, for at least twenty seconds.

Avoid Using a Sick Person's Bathroom:

If possible, set aside a different restroom for any sick person in your household until they recover, and limit close contact, as suggested.

Disinfect Contaminated Surfaces:

Disinfect hard surfaces with a bleach solution (1 cup per gallon of water) alternatively full-strength three percent hydrogen peroxide, both of which {can kill|
