Norovirus Research Papers

Nipah virus, Arena Virus and Francisella tularensis are bioterrorism agents. They work in various ways to harm the host. Francisella tularenis is considered a Tier 1 bioterrorism agent and Nipah virus is an overlap select agent that affects humans and agriculture both. They have been harmful in the past. Though, Nipah virus is a newer virus than the other two. This review will focus on their emergence, pathogenicity and symptoms of the diseases they cause.

The outbreak started on January 11th when almost 550 people became sick. 542 of the report people who became sick ate from El Toro in Tacoma. The other 22 people were infected from chain restaurants near by. These people have gotten sick from a WA-area norovirus with the Tacoma area. Residents of separate households began to send reports to the health department of possible food poisoning on January 5. All of these residents have recently eaten at the Tacoma restaurant. Everyone who has come forward has been treated. There is no incite if anyone have died.

The virus has received its name from its birth in Norwalk Ohio. It was responsible for a short term outbreak of gastroenteritis occurring in the students of Bronson elementary school in November of 1968. It wasn’t until 1972 the virus was examined and received its name as the Norwalk virus. Since its known birth, there have been many outbreaks with similar symptoms reported. It is believed the virus may belong to the family Caliciviridae. The Norwalk virus is actually part of a group of single-stranded RNA, non-enveloped viruses. Once a person is infected with the virus it begins to copy itself within small intestines. The symptoms would develop between 12 and 48 hours and tend to last 1-3 days.

What is the Norovirus? It is a acute gastroenteritis that is highly contagious and can affect anyone of any age (CDC.gov). Basically, a relative of the stomach flu. It can be seen anywhere, but it is most commonly found on a Cruise ship because it can spread quickly in the tight spaces. It is also called the Norwalk virus, mainly because it was first identified as the cause of an outbreak at a school in Norwalk, Ohio (Disabilitytravel.com). There is no known cure, only certain treatments to relieve the symptoms that come with it (Disabilitytravel.com). It has been seen often in the media over the past few years that it is scaring people away from cruising, thinking if they cruise, they will get sick. This is a disease that has made cruise line companies cut

The general herpes virus has become very common in society today. However, there are many treatments to cure this virus, such as Acyclovir(Zovirax) and Valacyclovir(Valtrex). Although these treatments cannot completely cure this virus, it will prevent the spread of cold sores, genital herpes, chicken pox, and shingles. Even though there are plenty positives for these two drugs, unfortunately, there are irritating side effects for taking them; for example, some side effects of Acyclovir can be nausea, diarrhea, dizziness, and vomiting. On the other hand, side effects of Valacyclovir contains more severe symptoms such as bruising or bleeding, bloody diarrhea, and red spots on the skin. About forty-five million people of the United States over the age of twelve have been infected with HSV-2, or Herpes Simplex Virus, and deal with these symptoms(WebMD).

BK virus is a common infection that can cause a mild respiratory illness. BK virus is also called polyomavirus. After the first infection, the virus remains in the kidneys and other parts of the urinary tract but is inactive (latent). BK virus very rarely causes problems in healthy people. People may live with this inactive virus for years and never have any more symptoms.

This essay is about Norwalk virus. How to prevent it and what to do if you recieve this illness. This essat also informs you on the history and recent outbreaks. How to avoid the illness and how it is transmitted are told in this illness. Death is also a topic in this essay and how many people die from norwalk virus annually.

Norwalk virus is a spherical single-stranded RNA virus. This virus is alive and can stay on objects and surfaces and still infect people for days or weeks. It can survive some disinfectants which makes it even harder to get rid of. Anyone can get Norwalk virus. Each year, norovirus causes 56,000 to 71,000 hospitalizations and 570 to 800 deaths, mostly in young children and the elderly. This virus causes

Many people are affected each year by what is usually misdiagnosed as the “stomach flu”. The official medical term for this illness is Norovirus, but is also known as Norwalk Virus. It was first seen in 1968 at Bronson Elementary School in Norwalk, Ohio. The first outbreak occurred at the elementary school, infecting 116 of the 223 students and teachers. Norovirus is a contagious virus that can lead to an infection called acute gastroenteritis. Gastroenteritis is an inflammation of the stomach and intestines, which results in diarrhea, vomiting, and stomach pain. In the United States alone, 19-21 million cases, 56,000-71,000 hospitalizations, and 570-800 deaths are reported each year (CDC).

Describe two innate (nonspecific) immune responses that might prevent an influenza virus from causing any noticeable infection, even if the virus enters your respiratory passages.

Noroviruses are the most common cause of viral gastroenteritis in humans, and affect people of all ages. Norovirus infection is characterised by nausea, forceful vomiting, watery diarrhoea, abdominal pain, and in some cases, loss of taste. General lethargy, weakness, muscle aches, headache, and low-grade fever may occur. The disease is usually self-limiting,

Norovirus is the most common cause of gastroenteritis. Infection is characterized by diarrhea, vomiting, and stomach pain, and fever or headaches may also occur. This usually develops 12 to 48 hours after being exposed. Individuals with norovirus may vomit and have diarrhea many times a day, leading to extreme dehydration, especially in young children, older adults, and people with other illnesses. The recovery typically occurs within 1 to 3 days.

The Norovirus belongs to the family called Caliciviridae. The norovirus causes gastroenteritis which is a condition that causes irritation and inflammation of the stomach and intestines. The norovirus is actually the most common cause of acute gastroenteritis.1

Human norovirues (HuNoVs) are highly contagious and cause gastrointestinal illnesses in humans. This virus rapidly spreads amongst people through feces or the consumption of contaminated food or water, causing strain on the economy due to health care costs and the loss of productivity by infected workers. Healthy adults were studied, to prove the hypothesis regarding the replication of noroviruses in different environments. Tests were done to demonstrate that human intestinal enteroids (HIE), the group of cultures that compromise the inner surfaces the small and large intestine, do support HuNoV growth. The positive results of these tests suggests that HuNoVs do not require bacteria for infection. Further studies conclude that HuNoVs are able
