Difference Between Norovirus and Norwalk

Norovirus is a type of virus that causes a contagious gastrointestinal problem. Norwalk is the originally discovered strain of the norovirus.

What is Norovirus?


Norovirus is a virus that causes a contagious blazon of gastrointestinal illness.

Genome and strains:

Norovirus is a term used to describe several strains of virus that cause a astringent course of stomach upset. The term also includes the original strain of the virus, the Norwalk virus. The norovirus strains today are known to vary in the genes ORF1 and ORF2. These particular gene sequences are responsible for making proteins on the viral capsid. Equally the genes mutate, so the viral capsids change, resulting in new strains.

Causative factors and manual:

The virus is highly contagious and is caught from a person who is ill and actively shedding virus particles through airsickness and diarrhea. The virus spreads fast and people can apace and easily catch the virus from contaminated surfaces in the environment every bit well as from ill people. People living in shut contact are most likely to catch norovirus.


Ofttimes the symptoms suggest that the person has norovirus, especially if they are in shut contact with other individuals who are ill. The only definitive diagnosis is made with a molecular RT-PCR test where the genetic material of the virus is tested for in a stool specimen.

Symptoms and complications:

Symptoms of norovirus include painful breadbasket cramps, diarrhea and severe vomiting, which lasts for anywhere from ane mean solar day to about iii or four days. Complications include dehydration, which tin cause depression blood pressure and even decease. Information technology does cause about 200,000 deaths world-broad, and thus, information technology should be taken seriously.

The person may need to exist given medicine to stop diarrhea and vomiting. In astringent cases, intravenous fluids need to be given to replenish the fluids lost from the body and to contrary the dehydration that results.

What is Norwalk?


A virus that was discovered in 1968 in Norwalk, Ohio, which causes severe gastrointestinal illness.

Genome and strains:

The Norwalk virus had a genome of no smaller than 7.5 kilobases in size. This was the original strain effectually in the late 1960s and early 1970s.

Causative factors and manual:

Norwalk virus is a type of norovirus that was hands transmitted amid people, causing many to become ill with symptoms of gastrointestinal distress.


Diagnosis was based on the symptoms that people had. The original strain, Norwalk caused an outbreak that occurred earlier molecular biology techniques had been inventing, limiting diagnosis of the condition.

Symptoms and complications:

Symptoms were probable stomach upset including vomiting and diarrhea along with painful stomach cramps. Complications of Norwalk would be similar all noroviruses, namely dehydration, hypotension, and mayhap, expiry.


Handling was likely to have been rehydration because people would have become dehydrated from the stomach upset.

Departure betwixt Norovirus and Norwalk


Norovirus is a an extremely contagious virus that causes gastrointestinal upset. Norwalk is the original and kickoff strain of the norovirus that was discovered in Norwalk.


Norovirus is a proper name used to describe a group of viruses with the original virus called Norwalk virus; the name norovirus was adopted post-1972 afterward the discovery of more strains of the virus. The Norwalk virus was first noticed sometime between 1968  and 1972 in Norwalk, Ohio.

The norovirus is found causing outbreaks all over the world in several countries. The Norwalk virus was responsible for an outbreak in the city of Norwalk in the United States.


The genome of the norovirus consists of a single-strand of RNA and the size of the genome varies anywhere from seven.iv to vii.7 kilobases; there is variation in the genes ORF1 and ORF2, which lawmaking for the capsid proteins. The genome of the Norwalk virus consists of a single-strand of RNA with a genome of a minimum size of 7.5 kilobases.

Number of strains

At that place are several strains of the norovirus considering of changes in the genes ORF1 and ORF2, which influences the viral proteins of the capsid. In that location is one strain of the Norwalk virus.

Summary of Norovirus and Norwalk

  • The Norwalk virus is the original strain of the norovirus.
  • The norovirus is a very contagious pathogen that causes gastrointestinal upset.
  • There are several strains of the norovirus today, occurring worldwide.


Why is norovirus named after Norwalk?

This is considering the outset fourth dimension the virus was discovered was in Norwalk, Ohio, so the disease was named subsequently this city.

Is there some other proper noun for norovirus?

The other name that is not often used is Norwalk virus. Generally, this name is used for the first, original strain of the norovirus, which was discovered in the late 1960s.

What does the Norwalk virus mean?

This is the name used to draw the original norovirus strain that was found in Norwalk, Ohio.

How serious is the Norwalk virus?

It tin be serious because it puts the person at hazard of dehydration, which can be dangerous.
